Abstract

The invention discloses an air intake temperature regulating system of a gas turbine. The air intake temperature regulating system of the gas turbine comprises a low-pressure gas compressor, a high-pressure gas compressor, an air compressor of the gas turbine, the gas turbine, an air heat exchanger, a hot-water-type absorption-type refrigerator and a gas heat exchanger, wherein a hot side air discharge pipe of the air heat exchanger is connected with the air compressor of the gas turbine; a water inlet and a water outlet at the cold side of the air heat exchanger are respectively communicated with a water outlet and a water inlet of the hot-water-type absorption-type refrigerator through pipelines; an air intake pipe at the hot side of the gas heat exchanger is connected with the lower-pressure gas compressor; an air exhaust pipe at the hot side of the gas heat exchanger is connected with the high-pressure gas compressor connected with the gas turbine; and a water inlet and a water outlet at the cold side of the gas heat exchanger are respectively connected with a water outlet and a water inlet of the hot-water-type absorption-type refrigerator through pipelines. The air intake temperature regulating system of the gas turbine provided by the invention is simple in system, and low in investment and running maintaining expense, and can be widely applied to a power generating technology of the gas turbine.

Description

technical field [0001] The invention relates to a temperature regulating system, in particular to a gas turbine air inlet temperature regulating system. Background technique [0002] In recent years, in the iron and steel industry, the gas-steam combined cycle power generation process using the remaining gas (high, coke, and converted coal gas) of the iron and steel plant to generate electricity has become quite large. It can efficiently utilize the waste energy and waste heat of the iron and steel plant. [0003] When the gas turbine is running, the power generation output is greatly affected by the temperature of the external atmospheric environment. For the same production site, the ambient temperature in winter is low, the air density is high, the atmospheric pressure is high, and the relative humidity is low. The power generation output of the gas turbine is high, even higher than the design condition value (the design working condition is ISO working condition, air in...
