Boiler blowdown is required to prevent corrosion by removing impurities that contribute to its formation in a steam boiler and to facilitate the generation of pure steam by preventing the carryover of impurities. Why Boiler Blowdown is Required? Proper blowdown procedures are necessary to maintain the solids content of the boiler water within specific limits and to quickly eliminate contaminants if the water becomes contaminated.

What is blow down?

The blow down valves are needle valves designed for operation in open position. Their function is mainly to control a continuous flow of steam and/or water under high differential pressure. For that reason the design and materials must be such as to minimize the effects of a fluid stream in condition of flashing or made of water containing sometimes abrasive particles. They are used in Boilers mostly cases. There are two types of boiler blowdowns - continuous and manual. A continuous blowdown utilizes a calibrated valve and a blowdown tap near the boiler water surface. As the name implies, it continuously takes water from the top of the boiler at a predetermined rate A continuous blowdown is an optional feature and may not be included on your steam boiler. However, all steam boilers should include a means for manual blowdown as standard equipment. Manual blowdowns are accomplished through tapings at the bottom of the boiler. These openings allow for the removal of solids that settle at the bottom of the boiler. Manual blowdown is also used to keep water level control devices and cutoffs clean of any solids that would interfere with their operation. All steam boilers require manual blowdown whether or not they are supplied with continuous blowdowns.

What is the cycle of the boiler?

Cycles are a measure of the dissolved solids in the boiler water in relation to the dissolved solids in the feedwater. For instance, if the measure of chlorides in the feedwater sample is 5 ppm and the chlorides in the boiler water sample is 50 ppm then the boiler water has been cycled ten times, 50/5 =10. That means that all of the water in the boiler (plus all the water that has been blown down) has been evaporated completely ten times, and replaced by the same amount of feedwater. Steam does not carry the dissolved solids out of the boiler, they remain behind, these are controlled with water treatment and a continuous blowdown (bottom blowoffs control or remove suspended solids).

What is a blow down header?

Blowdown is the process of pulling off of the bottom of a vessel like a drum to remove contaminants. Blowdown is also a method of reducing or controlling level in a vessel such as drum level. These blowdowns could be to a contained system or to sewer and can be continous or intermittent. Blowdown Header collects blowdown fluids from all source and transport it to the related handling, treatment or disposal system.

What is the difference between the operation of a automatic boiler and manual boiler?

boiler are working on same principal but automatic and manual boiler has difference that manual boiler working at single element loop and automatic boiler work at three element loop.single loop means when fuel increase mean load increase on boiler by adjusting fuel operator has to adjust steam drum level manualy , while automatic means when load increas, fuel increase steam drum level adjust automaticaly by watching fuel consumption.
