Overview:

A heat recovery boiler is the main equipment needed to recover the heat in a combined cycle. Most of the power plants use the exhaust heat of the gas turbine to produce steam. A combined cycle power plant includes a Brayton cycle (gas turbine) and a Rankin cycle (steam turbine) which is one of the most optimal cycles available for power generating systems.

In combined cycle power plants, the smoke from the gas turbine enters the boiler (HRSG) of the steam plant. Methods used for directing differ based on various types of boilers. The difference lies with the coils’ design of different parts of the boiler such as economizer, preheater, and superheater; if the coils’ arrangement is vertical, the exhaust smoke will go through HRSG coils horizontally and vice versa.

Sepahan MAPNA Engineering & Equipment Manufacturing Company produces the body of heat recovery boiler.
