Both the flue gas of a coal-fired power plant and the coal gas in the combined cycle (for use in a gas turbine) have a common task: denitrification and denitrification (and, of course, dust removal).
The flue gas discharged from the power plant without denitrification directly pollutes the atmosphere, while the combined cycle gas without purification will harm the hot end components of the gas turbine. Its exhaust also pollutes the environment. Therefore, in these industrial fields, we must use ammonia spray guns to solve these environmental problems.
Denitration spray nozzle is one of the important components of thermal power generation, large boiler, denitration dust removal complete set of equipment, it has high strength, high hardness, strong corrosion resistance, wear resistance, high temperature resistance and other excellent properties. However, in the process of use, it is inevitable that the nozzle of denitration spray gun will leak. This article will answer the solution of denitration nozzle drip, so that we can better solve the problem of denitration nozzle drip.
Drip of denitration nozzle is one of the most common problems in the application process, and the presence of drip doubt will obviously directly affect the pressure generated by the denitration nozzle during industrial operation, resulting in the effect of the denitration nozzle is not ideal. So what are we going to do about that?
The following is the factors and solutions of denitration nozzle dripping:
1, the denitration nozzle drip damage or needle deformation. Treatment: Replace nozzle set (nozzle, hood and needle).2. There are foreign bodies inside the port of the denitration nozzle. Treatment method: clean the nozzle and hood, and keep the internal cleaning of the nozzle.
3, the denitration nozzle needle seal nut is too tight. Treatment method: loosen the gun needle sealing nut.
4, gun needle return spring cracking or no device treatment: denitration nozzle replace or install gun needle return spring can be.
5, the needle and nozzle do not match. Treatment method: the denitration nozzle can be replaced by the appropriate needle.
