The air enters the air compressor from the air inlet channel is a pressure reduction and acceleration process, the temperature drop of 5 ℃ exists according to research, when the ambient temperature is low, water drops in the air are easy to freeze, so that the running air compressor is easy to have the danger of ice swallowing, and the vicious accident that the blades of the air compressor are damaged or interrupted is caused. Therefore, the air inlet heating system is arranged in the air inlet channel of the air compressor, so that water drops in the air can be prevented from freezing under the condition of low temperature in seasons, and the operation safety of the combined cycle unit is improved.
The output of the combined cycle unit is reduced along with the increase of the atmospheric temperature, so that the peak regulation capacity of the unit is insufficient in the peak period of power utilization in high-temperature seasons, and according to research, the rated power generation capacity of the gas turbine can be reduced by 1% when the environmental temperature is increased by 1 ℃ to the maximum. Therefore, it is necessary to take measures to reduce the inlet temperature of the gas turbine in high-temperature seasons to improve the output of the unit and the peak shaving performance of the unit.
The heat efficiency of the combined cycle unit is not good due to the fact that the atmospheric temperature is too low or too high, and therefore the air inlet temperature is increased in a low-temperature season and reduced in a high-temperature season by adopting appropriate measures, and the heat efficiency of the combined cycle unit is improved.

However, the high-grade steam source such as the steam extraction of a steam turbine or the main steam of a waste heat boiler is used as the heat medium, which can have adverse effects on the output and the heat efficiency of the unit.
The exhaust smoke of the combined cycle unit can take away a large amount of heat energy, if the exhaust smoke temperature of an F-stage combined cycle unit waste heat boiler can exceed 90 ℃, the exhaust smoke flow exceeds 2000t/h, the exhaust smoke waste heat not only has high utilization potential, but also can cause thermal pollution to the environment after being directly discharged; the acid dew point of the flue gas after the combustion of the natural gas is about 60-70 ℃, the dust content of the flue gas is small, and the corrosion and the blockage of a heat exchanger are not easy to cause, so that the flue gas waste heat utilization of the combined cycle unit has necessity and feasibility.
