Waste heat recovery boiler

The low exhaust gas temperature from gas turbines, typically ranging from 900 to 1050F, generates less steam on unit gas mass basis in the HRSG evaporator compared to a package boiler. On the other hand, in a steam generator or package boiler, the flue gas stream is cooled from adiabatic combustion temperature of 3300 F and hence generates a large amount of steam on unit gas mass basis.

Boiler feedwater economizers are placed in the boiler exhaust stack and heat boiler feedwater after the deaerator and before the boiler. Condensing economizers will have exhaust gas temperatures of between 70°F and 130°F (roughly between 20°C and 60°C), whereas feedwater economizers typically exhaust at well over 200°F (over 100°C).
