[0002] In the process of industrial production, a stable steam temperature is often required. However, in fact, the steam temperature sent from the thermal power plant is higher than the steam temperature required for chemical industry production. In this way, a tool is needed to reduce the steam temperature. The temperature reduction device is a tool that sprays low-temperature water into the superheated steam in the pipeline to reduce the temperature of the superheated steam. There are two commonly used desuperheaters. One is that the desuperheater is composed of a steam pipe, a nozzle, a desuperheating water pipe, a desuperheating water regulating valve, a stop valve and a check valve. The reheating steam system of the steam turbine in a thermal power plant has a desuperheating valve. In the actual operation process, its working medium is water. The reheater is essentially a steam superheater that heats the low-pressure steam that has done work and reaches a certain temperature. The reheater is a heater in the boiler that heats the water vapor coming out of the steam turbine into superheated steam. The reheater has two functions: one is to reduce the humidity of the water vapor, which is beneficial to protect the turbine blades; the other is to improve the relative internal efficiency and absolute internal efficiency of the steam turbine.
