The heat recovery steam generator (HRSG) provides the thermodynamic link between the gas turbines and steam turbines in a combined-cycle power plant. Each HRSG solution is custom-engineered to meet your desired operating flexibility and performance requirements.
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. Boiler blowdown
The HRSG can recover the heat from the gas turbine to produce steam/hot water for district heating or cooling. Large ocean vessels (e.g. Emma Maersk ) make use of heat recovery so that their oil-fired boilers can be shut down while underway.
Waste heat boilers are the significant energy saving equipment, utilize the heat in flue gases from combustion processes or hot extract air from industrial processes to generate hot water or saturated steam Otherwise, the waste heat boiler could be used in oil gas fired combined cycle units, and take advantage of the high temperature flue gas heat discharged by gas turbine
