Combined Heat and Power Technology Fact Sheets Series

A steam turbine is driven with high pressure steam produced by a boiler or heat recovery steam generator (HRSG). Unlike gas turbines or microturbines, steam turbines do not directly consume fuel. Rather, the fuel driving the process is the fired boiler or plant equipment that produces heat for the HRSG (e.g., a gas turbine).

Aug 26, 2011· Heat recovery steam generators behind gas turbines are either unfired or fired. In the fired category, depending on the firing temperature, HRSGs are classified as supplementary fired or furnace fired. Typically, turbine exhaust gases have 14% to 15% by volume of oxygen in the exhaust, which can be used as combustion air.

Heat recovery steam generators. A heat recovery steam generator (HRSG) is a steam boiler that uses hot exhaust gases from the gas turbines or reciprocating engines in a CHP plant to heat up water and generate steam. The steam, in turn, drives a steam turbine or is used in industrial processes that require heat.
