SNCR PROTECTION GUARD OF REDUCING AGENT INJECTIONNOZZLE

摘要

The present utility model relates to a device to solve the problem generated when applying the SNCR process to reduce nitrogen oxides in a CFBC boiler. A CFBC boiler is a device with an increased heat delivery efficiency and combustion efficiency by circulating a medium such as fluid sand, and has various advantage. However, the medium circulating at a high speed causes erosion of the external wall and a water pipe of the boiler, and causes erosion of a reducing agent injection nozzle mounted for the SNCR process to deform and to change the injection form. The present utility model relates to an SNCR injection nozzle protective device in order to prevent the erosion of the reducing agent injection nozzle due to the high speed medium.
