Abstract
The invention discloses a gas turbine intake heating control system which comprises a heat exchanger, a hot water circulation pump, a water feed tank and an air heat exchanger. The heat exchanger, the hot water circulation pump, the water feed tank and the air heat exchanger are sequentially connected through hot water supply pipes. An electric adjusting valve is further installed between the water feed tank and the air heat exchanger. The air heat exchanger is further connected with the heat exchanger through a hot water return pipe. The gas turbine intake heating control system further comprises a control cabinet. The control cabinet is connected with the hot water supply pipes, the hot water return pipe and the air heat exchanger. The water flow in the hot water supply pipes and the hot water return pipe is controlled. The gas turbine intake heating control system is high in safety; once a problem or a breakdown happens to a certain position, alarming is started through the corresponding alarming function, the system is cut off at the same time, and the safety of the whole is ensured; the automation degree is high, and automatic control is achieved through the control cabinet; and the hot water flow of a pipeline is adjusted by monitoring the temperature of an air outlet of the surface type air heat exchanger, and therefore it is ensured that a unit runs in an interval with the optimal performance.
