The invention relates to a method of increasing the total efficiency of a PFBC power plant with a gas turbine cycle and a steam turbine cycle. Low grade heat is utilized for generation of steam which is injected into the combustor (10) and increases the mass flow through the gas turbine (30) and hence the gas turbine power generated. Preferably, waste gases from the gas turbine (30) of the plant are utilized for generation of steam in a steam generator (84) separate from the main steam cycle (38, 40). The invention also relates to a PFBC power plant, in which low grade steam is injected into the combustor (10). |
