Boiler blowdownis water intentionally wasted from aboilerto avoid concentration of impurities during continuing evaporation of steam. The water is blown out of the boiler with some force by steam pressure within the boiler. Bottom blowdown used with early boilers caused abrupt downward adjustment of boiler water level and was customarily expelled downward to avoid the safety hazard of showering hot water on nearby individuals.

Some boiler water treatments cause precipitation of impurities as insoluble particles anticipating those particles will settle to the bottom of the boiler before they become entrained in water circulating past the heat exchange surfaces. These water treatments often include compounds forming a sludge to entrap such particles; and boilers intended for such water treatment include a structure called a mud drum at the lowest part of the boiler. Bottom blowdown involves periodically opening valves in the mud drum to allow boiler pressure to force accumulated sludge out of the boiler. Similar blowdown connections at the bottom of water wall headers are blown down less frequently. Several short blowdown events remove sludge more effectively than a single continuous blowdown. Shorter blowdown events cause less significant changes in boiler water level, and are safer during periods of high steam demand.

Bottom blowdown piping drains the lowest parts of the boiler so it can be used to drain the boiler for servicing. Bottom blowdown piping must be of a diameter large enough to minimize the risk of being plugged with baked sludge. Modern boilers discharge bottom blowdown to a blowoff tank where the blowdown can flash and vent steam upwards without entraining water which might cause burns. A pipe near the bottom of the blowoff tank maintains a water level below the blowdown entry point and allows cooler water remaining from earlier blowdown events to drain from the tank first.

The United Brass quick opening boiler blow off valve has been designed for the rugged service of boiler treatment and scale. The cast steel knife gate valve conforms to Class 300 of ANSI B16.34 and features a stainless steel seat and disc hardened to Rockwell 60. ASME Boiler and Pressure Vessel Code Sections 1 PG-42.1.12 and Power Piping Code ASME B 31.1 Table 126.1 reference steel valves to ANSI B16.34. The sliding disc provides a cleaning action that keeps the seating area clear of scale and debris.

Wizards of NOS developed the uniquenitrous Safe Pressure Relief Valve (SPRV) to provide our customers with an increased level of safety that’s not available from any other nitrous company. The SPRV also boasts improved performance and reliability to compliment the other advanced, high quality market leading nitrous components WON offer.

The SPRV is a direct replacement for the basic and potentially dangerous blow off/rupture discs supplied as standard on all other brands of nitrous oxide bottle valve. It is designed to release small amounts of nitrous should the pressure in the bottle try to exceed the desired safe level, rather than dump the whole contents at an elevated unsafe pressure, as is the case with a blow off/rupture disc.

This Race Spec version allows for the use of a blow down tube or use of 6AN hose coupled with bulkhead fittings. The blow down is used to vent any over pressure to atmosphere outside of the vehicle. These valves are designed not to release the full contents of a cylinder like blow-off discs in their explosive manner. The SPRV will bleed progressively as pressure rises above the threshold in a safe and un-alarming manner and therefore do not require this tubing for safe function. However due to numerous regulations being unchanged to accomodate this technology we have provided this version where regulation needs it.

A blow off/rupture disc is a small disk usually made of brass or copper, which is retained in the back of the bottle valve as a weak link, much like a fuse is a weak link in an electrical circuit. If the pressure in the bottle reaches a certain level (usually ‘intended’ to be around 100 bar) the disc will rupture allowing all the bottle contents to escape. The idea is that the disc ruptures before the pressure becomes great enough to rupture the bottle itself.

1) If you are close to the valve when the disc ruptures, it can result in a painful freeze burn because large volumes of liquid nitrous are rapidly dumped to atmosphere, in an a totally uncontrolled manner. To see a video demonstration of the results of this please CLICK HERE

ASTM A216 Gr. WCB Automatic Blowdown Valve is used for sludge removal in boiler systems. Suraj Metal Corporation is a leading manufacturer and supplier of the different types of blowdown valves such as the Cast Iron Steam Boiler Blowdown Valvesand others for various industrial applications.

The boiler applications boil the water and therefore the impurities in water become sludge and get deposited at the bottom of the tanks and boilers. The blowdown systems are designed with more than one valve and are controlled by the user or operator. The GG25 Cast Iron Angle Blowdown Valveis one of the most used due to the high temperature applications. The sludge is removed by the opening of the valve at certain point. Some of the systems use automated time intervals while some other use the amount of sludge that builds up during the operations. The GS-C25 cast steel Steam Blowdown Valveis available from us with other types and grades as well. The purging of the sludge is made easy with the blow down valves. Depending on the water quality, the use of different types of valves such as the Cast Steel Blowdown Valvesis decided. You can contact us for more detailed information on the different types and prices of these valves.

The primary purpose of a blowdown valve is to regulate a constant flow of steam/fluid at an elevated differential pressure and also to remove dirt, sediment, and limescale.

Blowdown valves are used either continuously or intermittently depending on the service requirements and play an important role in fossil fuel boilers to remove dissolved solids from the boiler water. Generally, only one blowdown valve is used in a boiler. If more than one blowdown valve is used in a boiler, the two valves are often used in series to minimize erosion. In this design, one valve acts as the shutoff valve, and the other valve acts as the drain valve. The shutoff valve is usually opened first and closed last. To minimize erosion of the disc and seat, both valves are opened quickly and simultaneously. Most importantly, care should be taken to avoid trapping rust particles in the valve during the drainage process. This is accomplished by opening the valves again so that any remaining rust particles are flushed out with the next passage of steam through the piping. Whenever a boiler is taken out of service for maintenance, the bottom drain valve is usually rebuilt or replaced.

Generally, we classify blowdown valves into two categories, continuous blowdown(CBD) valves, and intermittent blowdown (IBD) valves, since the intermittent blowdown valve works close to the bottom of the boiler, we also call it a bottom blowdown valve.

The continuous blowdown valve (CBD) is designed to operate in a constant open position to maintain the TDS level in the boiler ladle by continuously releasing water from the boiler water surface through the blowdown tap. Some engineers also name this valve a surface blowdown valve.

The purpose of the bottom blowdown valve is to remove boiler sediment to keep the boiler water in compliance with manufacturing standards to improve the efficiency and performance of the boiler.

The function of the intermittent blowdown valve is to release accumulated sludge and sewage through a drain near the bottom of the boiler at regular periods, usually with a predetermined time cycle. There is a special requirement for the bottom blowdown valve to ensure that the valve can be tightly closed after repeated draining actions.

In boiler operation, the deposition of impurities is highest at the point where liquid water is converted to steam. The resulting scale forms an insulating layer, impeding the flow of heat through the equipment. As the thickness of the formed scale increases, the rate of steam generation decreases, as does the rate of heat flow. In addition, due to the accumulation of heat, the temperature of the metal surface may increase to the point where the metal surface itself may be damaged. Generally, drain valves are installed on equipment in processes where the working fluid is water. If the water contains solid impurities and some of the water continues to evaporate through some mechanism, such as drafting in a cooling tower or vaporization in a boiler, then the concentration of solid impurities in other water that accumulates in the equipment increases. Drain valves are used to drain a certain amount of liquid from equipment that contains solid impurities that by their nature are insoluble in the working fluid and may be deposited on the surface of the equipment, causing problems with the operation of the equipment.

If the water in the boiler is not well treated in the preparation stage, the density of insoluble substances (TDS) will increase due to steam generation. If the determined limit is exceeded, it can cause damage to the boiler and piping, and eventually lead to equipment failure. Insoluble materials are carried along with steam, and they can increase the conductivity of condensate and cause energy loss. Insoluble materials typically include calcium and magnesium salts, and these insoluble substances are deposited during the steam production process, and we need to remove them through a number of techniques to achieve optimum TDS levels. This operation is known as blowdown, and the valve used for this purpose is known as a blowdown valve.

Continuous blowdown: Also called surface blowdown, it is a continuous process of draining the most concentrated furnace water from the surface layer of the steam ladle furnace water. The purpose is to reduce the salinity and alkalinity of the boiler water to prevent the concentration of the furnace water from being too high and affecting the quality of steam. Continuous drain is generally installed in the steam ladle normal water level (i.e. “0” level) 80-100mm below. Furnace water is continuously evaporated and concentrated so that the highest concentration of salt is near the water surface. Therefore, the continuous drainage orifice should be installed in the area with the highest density of furnace water, in order to continuously discharge high-density furnace water and supplement it with clean feed water, so as to improve the quality of boiler water, and the drainage rate is generally about 1% of the evaporation volume.

The drain valve usually uses a gate valve or globe valve. The nominal diameter of the drain valve is DN25~50, rated evaporation ≥1t/h or working pressure ≥0.7Mpa boiler, the drain pipe should be installed with two drain valves in series.

The traditional design is a combination of 1 slow drain (with gate valve) + 1 fast drain (high-temperature ball valve), but due to the PTFE soft seal inside the ball valve, the valve seat is easily deformed by aging due to the long-term high temperature above 140℃, which eventually leads to valve leakage. And the gate valve sealing groove is easy to accumulate impurities, the gate does not close tightly and leaks. So this design service life is short.

Use one slow discharge (with bellows shut off globe valve S25FGB) + one fast discharge (quick-opening bellows shut-off valve S25F). The quick opening bellows globe valve S25FGB-1 is a special replacement for the high-temperature ball valve.

Advantages The switch is fast and convenient, only needs to make within 180 ℃ rotation, you can achieve from fully open to fully closed or fully closed to fully open, and the sealing performance of the globe valve, as well as the quick switching performance of the ball valve.

When discharging, the blowdown valve is subjected to high-temperature liquid flushing and dirt wear and will be cooled to room temperature after it stops draining. In order to improve the drain valve’s frequent poor working conditions such as pressure difference (large differential pressure drop), scale corrosion and wear vibration, and thermal shock,the series drain valve has a certain operation procedure: when discharging, valve 1 (slow opening blowdown valve) is opened first, then valve 2 (quick opening blowdown valve) is opened; when stopping discharging, valve 2 is closed first, then valve 1 is closed.

Valve 1 is a slow-opening blowdown valve, which should have the ability to resist alkaline corrosion of furnace water; valve 2 is a fast-opening blowdown valve, which should meet the action and time requirements of drainage.

The blowdown valves are a very popular category of pipe valves, used in a wide variety of applications. They are used for operation in open position. The main function of blowdown valve is mainly to control a continuous flow of steam /fluid under high differential pressure. The outstanding feature of this type of valve is that it can maintain fluid tightness and it is easily operated without the help of any wedging action.

At shut-down the valve opens to bleed the air-oil separator to atmosphere. This is when a pressure is applied. The valve can also be used as a by-pass valve to bleed air with the help of the compressor at start-up.

The design and materials of blow down valves must be such as to minimize the effects of a fluid stream in conditions where water contains sometimes abrasive particles.

Surface blowdown valve: This is supposed to be the best choice for blowdown valves. It is used for removing dissolved solids. It helps in removing solids at those points where they are most concentrated.

Bottom blowdown valve: This is another type of valve for controlling dissolved solids. The function of this type of valve is to remove sludge which gathers in the bottom of the boiler.

• Single Stage Valve in Angle Pattern Block Body design with replaceable seat bush feature available for high pressure drop application and handling high flow.

• Multi stage Valve in Angle Pattern Block Body design with replaceable seat bush feature available for high pressure drop application and high flow.

• Single piece stem and plug assembly: No vibration of plug when the valve is kept semi open position. Cracking of Stellited seat due to High frequency vibration of plug when handling high pressure drop across valve seat is a common occurrence. Can be avoided by considering this feature.

• Non Rotating along with Single Piece Stem and Plug Design feature ensures that the plug does not rotate when it sits on the valve seats. It also prevents damage to seat due to entrapped solid such as pipe scales or entrapped solid when the valve operator puts excess effort on handwheel to ensure tightness at seat.

• Roller Burnishing in Gland packing section gives a mirror finish to the spindle and helps reduce ware and tare of the gland packing. Effort required to operate the valve reduces due to reduced friction at the gland packing section due to this feature.

• Control Cone feature (SN 46) with slots machined as per the valve discharge capacity. Valve plug specially designed such that there is no real flow till the plug seating area has move a minimum of 10% of the total lift away from the valve seat. This helps to separate the seating area from the throttling of High pressure reduction area. As a result the harmful effects of cavitation and flashing do not affect the seating area of the valve enhancing the seat life .

Relief and safety Valves are used in high pressure systems to control the pressure and keep balance of the system. The different between safety valves and relief valves is that the safety valves fully open or close under a certain pressure while the relief valves can open in proportion to the pressure in front of them. The safety and pressure relief valves are used automatically. They both operate under similar conditions. When the pressure builds up in a system, it has to be managed by releasing the material to flow through. These valves have a threshold pressure at which they open. The consolidated safety and safety relief valves comprise of a bonnet vent and bellow with springs.

The springs are set up for the threshold pressure and when the pressure exceeds the threshold, the spring is pushed into the bonnet vent and the bellow opens the valve. The Safety Relief Valves can be open and shut valves. They either open or shut off at any given pressure. This is mostly for the safety of an application not to explode under high pressure. The Pressure Relief Valve on the other hand releases the material after the threshold pressure, but not fully. If the pressure is slightly higher the threshold, then the valve opens slightly. If the pressure is very high above the threshold, it opens wider. It also functions in the same manner when the pressure drops down. The valve closes in proportion to the pressure. The safety valve shuts down at once only when the pressure is below the threshold.

Relief Valves are designed to control pressure in a system While Safety Valves are used for controlling the pressure in a system they release pressure immediately in the event of an emergency or system failure

The Setpoint of relief valve is usually set at 10 Percent above working pressure limit while safety valve is usually set at 3% above working pressure limit.

If you are operating systems that can only be off for short periods of time, it is sensible to keep a spare valve to swap over and then the removed valve can be inspected and recertified.
