Heat Recovery Steam Generators (HRSGs), Part 3: Predicting

Supplementary firing is an efficient method of generating additional steam in HRSGs. The additional boiler duty is nearly equal to the fuel input, which suggests that supplementary firing is 100% efficient. Compare this to conventional boilers, where fuel efficiency is about 90-93%.

Heat Recovery Steam Generators (HRSG) | Boilers - Product

A heat recovery steam generator (HRSG) is one of the major pieces of equipment in a gas turbine combined cycle power plant that boasts a high thermal efficiency and produces minimal CO 2 emissions. An HRSG is a kind of heat exchanger that recovers heat from the exhaust gases of a gas turbine to an extreme degree.

The HRSG forms a major part of the steam system. In the combined -cycle mode, the efficiency of the combined gas - turbine-plus-HRSG system can reach 55 - 60% (LHV basis) with today's ad vanced machines, while in the cogenera tion mode, system efficiency can be as high as 75-85%.

The resulting unit looks very similar to a conventional fired packaged boiler, such as this O-type boiler that sits behind a Taurus 60 at a military base and produces 80,000 lb/hr of 250-psig saturated steam.

In fact it can be shown that in a cogeneration plant, it makes more sense to generate additional steam in the HRSG rather than in the package boiler, as the efficiency of steam generation is only about 92 to 93 % (LHV) in a boiler versus 100 % in a HRSG.
