The treatment of boiler water can be put into two parts. These are internal treatment and external treatment. (Sendelbach, p. 131) [4] The internal treatment is for boiler feed water and external treatment is for make-up feed water and the condensate part of the system. Internal treatment protects against feed water hardness by preventing ...
With oxygenated treatment, oxygen is injected into the feedwater to keep the oxygen level between 30 and 50 ppb. OT programs are most commonly used in supercritical (i.e. >3250psi) power boilers. The ability to change an existing sub-critical boiler over to an OT program is very limited.
Boiler water is liquid water within a boiler, or in associated piping, pumps and other equipment, that is intended for evaporation into steam.The term may also be applied to raw water intended for use in boilers, treated boiler feedwater, steam condensate being returned to a boiler, or boiler blowdown being removed from a boiler.
The boiler feedwater is sprayed into section where it is preheated by the rising steam from the sparger. The purpose of the feedwater spray nozzle and the preheat section is to heat the boiler feedwater to its saturation temperature to facilitate stripping out the dissolved gases in the following deaeration section. The preheated feedwater then ...
Electrodeionization (EDI) is a water treatment technology that utilizes DC power, ion exchange membranes, and ion exchange resin to deionize water. EDI is typically employed as a polishing treatment following reverse osmosis (RO), and is used in the production of ultrapure water. It differs from other RO polishing methods, like chemically ...
The forced circulation boiler begins the same as a natural circulation boiler, at the feed water pump. Water is introduced into the steam drum and is circulated around the boiler, leaving only as steam. What makes the forced circulation boiler different is its use of a secondary pump that circulates water through the boiler.
A boiler feedwater pump is a specific type of pump used to pump feedwater into a steam boiler.The water may be freshly supplied or returning condensate produced as a result of the condensation of the steam produced by the boiler.
in locomotive boilers, a feed water check valve placed on the top of the boiler drum. This encourages rapid mixing of the cold feedwater with the hot steam, reducing the risk of thermal shock to the heated parts of the boiler. Tubeplate a plate across the barrel of a fire-tube boiler, containing many small holes to receive the fire-tubes.
