Abstract
An electric power generating system employing a gas turbine (1) and a steam turbine (5) and a gasifier (9) supplying fuel-gas to the gas turbine (1) and to a steam generating fluidized bed combustor (37), the latter providing steam for the steam turbine (5). An auxiliary steam turbine (21), driving an electric generator (22), is also supplied by the circulating fluidized bed combustor steam generator (37). Since the gasifier (9) cannot be reversibly turned down easily, on a fall in load on the main steam turbine (5), the excess steam generated is diverted to the auxiliary steam generator (21) and the gasifier (9) kept running efficiently.
