Boiler feedwater - Wikipedia

Boiler feedwater. Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank.

Power Boiler Feedwater and Steam - Convergence Training

Course Details. The water supplied to the boiler, which is converted to steam, is called feedwater. This feedwater system removes any impurities in the condensate, which is steam converted back to water, preheats and pressurizes it then returns it to the power boiler steam drum. The power boiler control system maintains the proper flow of feedwater to the boiler.

Boiler feedwater control valve leakage - what to do to

Given that there are up to eight critical boiler feedwater valves per HRSG, maintenance or replacement of these valves can be very expensive. The cost of feedwater valves for a two-on-one combined cycle can run more than $100,000. While many problems can be traced to frequent cycling, there are other reasons for valve damage as detailed above.
