Technical Field

[0002] A gas turbine is an internal combustion power machine that uses continuously flowing gas as the working medium to drive the impeller to rotate at high speed, converting the energy of fuel into useful work. It is a rotating impeller type heat engine. In the main processes of air and gas, the gas turbine cycle composed of only three major components, namely a compressor, a combustor, and a gas turbine, is generally referred to as a simple cycle.
[0003] The compressor sucks in air from the external atmospheric environment and compresses it step by step through an axial flow compressor to increase its pressure. At the same time, the air temperature also increases accordingly. The compressed air is sent to the combustor to be mixed with the injected fuel and burned to generate high-temperature and high-pressure gas. Then, it enters the turbine to expand and do work, driving the turbine to drive the compressor and the external load rotor to rotate at high speed together, realizing the partial conversion of the chemical energy of gas or liquid fuel into mechanical work and outputting electric work. The exhaust gas discharged from the turbine is discharged to the atmosphere to release heat naturally. In this way, the gas turbine converts the chemical energy of fuel into heat energy and then converts part of the heat energy into mechanical energy.
[0004] Specifically, when the weather is dry and the relative humidity of the air is lower than 30%, the nitrogen oxides in the flue gas emissions of the gas turbine exceed the standard. To reduce the nitrogen oxide emissions in the flue gas emissions of the gas turbine, it is necessary to humidify the air at the compressor inlet.
