Mechanical or electrical energy and heat producing method, involves supplying hot water to heat recuperation unit, and preheating cold water by heat exchange with hot water before cold water is preheated by degasser

摘要

The method involves producing mechanical or electrical energy (3) and hot combustion gas (4) by a gas turbine (1) of a cogeneration unit (A). Hot water (6) is supplied to a heat recuperation unit (5) and vaporized by recuperating the heat from the combustion gas. Hot water (11) preheated by a degasser (10) of a thermal power plant (B) is supplied to the plant. Cold water (9) is supplied to the degasser, where the temperature of the water (9) is lower than that of the water (6). The cold water is preheated by heat exchange with the water (6) before the water (9) is preheated by the degasser.
