Description

technical field

[0001] The invention relates to the technical field of steam desuperheaters, in particular to a water spray desuperheater. Background technique

[0002] The water spray desuperheater is a desuperheating device that sprays cooling water directly into the superheated steam flow passing through the steam pipe. The principle is: when the cooling water is mixed into the superheated steam, it will absorb heat from the superheated steam and turn it into steam, and the superheated steam will reduce the temperature from the original high temperature point to a certain low temperature point due to the heat release, so as to achieve superheating. The purpose of steam desuperheating. If the cooling water is sprayed into the superheated steam pipe as very fine water droplets or mist, the cooling water and the superheated steam are mixed more uniformly by the steam flow. The water spray desuperheater is characterized by simple structure, large temperature adjustment rang...
