3.6 Heat recovery boiler. The heat recovery boiler serves to cool the SO2 -bearing product gas and produce steam for electricity generation. Cooling occurs by feeding low-temperature boiler feed water around the fire tubes ( Fig. 3.4 ). The boiler feed water is condensed steam after electricity generation that has been conditioned in a deaerator.

Similarly, a steam boiler where combustion gases give up their heat to water in order to achieve evaporation, may be described as a fired heat exchanger. However, the term is often more specifically applied to shell and tube heat exchangers or plate heat exchangers, where a primary fluid such as steam is used to heat a process fluid.

2021/6/24 · Gas condensing boiler is a steam boiler that condenses the vapor in the flue gas into water by condenser. It recovers the latent heat released during condensation process, and reuses such heat to achieve or above thermal efficiency. The flue gas temperature of conventional gas fired boilers is generally 160~250℃.

2022/1/4 · 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 …

In a steam boiler the heat from the flue gas is transferred to the water, which then turns into steam. Downstream of the boiler the flue gases are still high in temperature and are typically 50ºC or more above the steam temperature. Flue gas heat exchangers downstream the boiler can recover this waste heat and improve the boiler fuel efficiency.
