Abstract

The invention belongs to the technical field of cogeneration and waste heat utilization and particularly relates to a combined system and method of flue gas waste heat recovery and inlet-gas cooling of a gas turbine cycle. The combined system comprises an inlet-gas cooler, a flue gas-water heat exchanger, a refrigeration device and a cooling tower. The refrigeration device is connected with the inlet-gas cooler through a first chilled water cycle pipeline, connected with the flue gas-water heat exchanger through a second chilled water cycle pipeline, connected with the cooling tower through afirst cooling pipe cycle pipeline and connected with a heating network pipeline through a second cooling water cycle pipeline. Inlet-gas cooling and flue gas waste heat recovery and utilization of a gas turbine are achieved, output force of the gas turbine in summer can reach the rated load, the energy utilization efficiency of the gas turbine combined cycle is improved, the defects that the gas engine is poor in inlet-gas cooling investment economical efficiency and limited in cooling effect are completely overcome, and the economical efficiency of a whole unit is improved.

Description

technical field [0001] The invention belongs to the technical field of cogeneration of heat and power and utilization of waste heat, and in particular relates to a combined system and method for waste heat recovery of gas turbine circulating flue gas and intake air cooling. Background technique [0002] Gas turbine combined cycle refers to gas-steam turbine combined cycle. The air is compressed by the compressor driven by the gas turbine and enters the combustion chamber of the gas turbine. After being mixed with fuel, the high-temperature and high-pressure flue gas formed drives the gas turbine to do work. Part of the work is used to drive the compressor, and the other part drives the generator to generate electricity. The high-temperature flue gas discharged from the gas turbine heats the water in the waste heat boiler to generate high-temperature and high-pressure steam, which is used to drive the steam turbine to generate electricity. The above-mentioned gas turbine and...
