ABSTRACT:
Subject of the invention is a process for the realization of cogenerative supply of electricity and heat, and in given case for their combination with waste heat recovery, particularly in case of combined (gas-steam) cycle industrial power plants.
The essential feature of the invention is that during the season without heat demand the condenser with heating capacity N is operated by cooling with cooling tower, and during the heat-intensive season it is operated at a higher temperature required for the heat supplying operation mode, while the cooling tower (7) is disconnected partially or completely, and the resultant reduction of the specific expansion and heating capacity of the steam turbine (4) is compensated by increasing the steam parameters and steam output of the waste heat recovery boiler (3) with supplementary firing (11).
