Filed: 1981-10-14
Abstract: In a power plant which includes a gas turbine unit and a steam turbine unit which units are supplied with gas and steam, respectively, from a common combustion chamber 1, 2 in which combustion takes place under pressure in a fluidized bed 3, the units of the plant are designed to operate efficiently with each other at an ambient temperature (To), which is usually about +30 DEG C. To enable the plant to be used to the maximum at ambient temperatures below To, when the flow of combustion air to the fluidized bed 3 increases and more fuel can be burnt, the fuel supply to the bed 3 from a container 50 via a conduit 33 is increased in dependence on the available quantity of combustion air, e.g. as measured at 53. Simultaneously the temperature of the fluidized bed 3 is regulated by injecting water or water vapour into the bed 3 from a container 34 via a conduit 35 e.g. by a transducer 38 in the combustion chamber which controls this injection of water or water vapour by regulating a control valve 36 in the conduit 35. The steam formed by the injected water or water vapour expands in the gas turbine unit together with the combustion gas and increases the power of the unit.   <IMAGE>
