Abstract

The invention relates to the technical field of industrial energy conservation and emission reduction and particularly discloses a waste heat utilization system of a gas-steam combined cycle generator set. The waste heat utilization system of the gas-steam combined cycle generator set comprises steam coming out of the gas-steam combined cycle generator set and entering a condenser and is characterized in that a water outlet pipe of the condenser is connected with a circulating water pump, a water cooling tower, a heat supply network water return pipe and an initial heat supply station in parallel, the initial heat supply station is communicated through a heat supply network circulating water pump, and the initial heat supply station is connected with a steam turbine. Steam exhausted by the steam turbine is totally recovered to prevent loss, zero cold source loss is achieved, the thermal efficiency of the whole system in the heat supply period reaches more than 90 percent, and the national requirements for energy conservation and emission reduction are met.

Description

(1) Technical field [0001] The invention relates to the technical field of industrial energy saving and emission reduction, in particular to a waste heat utilization system of a gas-steam combined cycle generator set. (2) Background technology [0002] In a conventional large-scale gas-steam combined cycle generator set, the working process is that the air is compressed by the gas turbine compressor and then enters the combustion chamber and is mixed with natural gas for combustion. The boiler absorbs the waste heat of the high-temperature flue gas to generate steam, which enters the steam turbine coaxial with the gas turbine to do work, and drives the generator together to generate electricity. . [0003] Although the gas-steam combined cycle improves the thermal efficiency of the system, the exhaust steam after work is released, and a large amount of latent heat of vaporization is released during the condensation process of the condenser, causing heat waste and reducing t...
