Abstract

The invention designs a water inlet and ice prevention detection system of a gas turbine. The water inlet and ice prevention detection system is used for improving safety and efficiency of a gas turbine device running under a low-temperature environment. A frozen state of an air inlet system is accurately monitored and judged by the gas turbine device by the proposed water inlet and ice preventiondetection system of the gas turbine, and the purposes of energy saving and efficiency improvement are achieved on the premise that an air inlet condition is enabled to conform to safety running of the gas turbine by controlling an air inlet heating device to start and close within reasonable time. The water inlet and ice prevention detection system has the characteristics of high frozen detectionaccuracy, rapid response, simple structure and arrangement flexibility, and the detection function demand of the air inlet and ice prevention detection system of a land gas turbine and a ship gas turbine can be satisfied.

Description

technical field [0001] The invention belongs to the technical field of safe operation and energy saving and efficiency enhancement of a gas turbine device, and in particular relates to a gas turbine intake air anti-icing detection system. Background technique [0002] A gas turbine is a power device that uses air as the main medium and continuously compresses, heats up, and expands through impeller machinery to perform work. The gas turbine compressor is continuously rotating at high speed, and the blade tip speed is very high, so any fine particles entrained in the air may cause great harm to the safe operation of the blades. In a cold and high-humidity environment, the water vapor in the air may condense into ice or frost, which will adhere to the air intake system pipes, filter screens, etc., causing the air intake system to be blocked, or broken ice cubes will be sucked into the compressor. Both situations will bring huge potential safety hazards to the operation of gas...
