The invention relates to a humidification and emission reduction device for a gas turbine and a control method thereof. A gas inlet chamber of the gas turbine comprises a fan-shaped atomizing chamber and a rectangular filtering chamber, wherein the arc-shaped side wall of the fan-shaped atomizing chamber is a gas inlet face; multiple arc-shaped supports parallel to the arc-shaped side wall are installed on an indoor top plate of the fan-shaped atomizing chamber; an arc-shaped water supply branch pipe is installed on each arc-shaped support; and multiple uniformly arranged atomizing nozzles are installed on the arc-shaped water supply branch pipes. According to the humidification and emission reduction device for the gas turbine and the control method thereof provided by the invention, the fan-shaped atomizing chamber and the arc-shaped water supply branch pipes arranged in parallel are adopted, and the working pressure of the atomizing nozzles on the arc-shaped water supply branch pipes is sequentially increased in the gas flowing direction, so that the spray particle sizes of the atomizing nozzles in the gas flowing direction are sequentially reduced, the gas is atomized step by step in the gas flowing process, atomization parameters can be accurately controlled, atomization water can be saved, the atomization effect can be improved at the same time, and nitrogen oxide emission can be reduced by humidifying intake gas of the gas turbine.
Description
technical field [0001] The invention relates to gas power generation technology, in particular to a gas turbine humidification and emission reduction device and its control method. Background technique [0002] The national standard "Emission Standards of Air Pollutants for Thermal Power Plants" stipulates that the maximum emission limit of nitrogen oxides in the flue gas of large gas turbines is 50 mg per cubic meter. There are two main sources of nitrogen oxides emitted by gas turbines, namely thermal nitrogen oxides and fuel nitrogen oxides; because the nitrogen content in natural gas is extremely low, fuel nitrogen oxides in flue gas can be ignored; natural gas is burning The amount of thermal nitrogen oxides produced during chamber combustion is related to factors such as combustion temperature, air-fuel ratio, and combustion residence time. [0003] When the intake air temperature of the gas turbine is high, the performance will decrease. There are many ways to reduce...
