Abstract

The invention discloses a boiler flue and a denitrification system. The boiler flue comprises a vertical flue part and a turning flue part, wherein the vertical flue part is connected with the turningflue part, an ash damper and a straight plate are obliquely installed on the inner side wall of the vertical flue part, and an arc-shaped plate is installed on the turning flue part. According to theboiler flue, the ash damper and the straight plate are obliquely installed on the vertical flue part, so that the speed and distribution of smoke in the vertical flue part are adjusted; the arc-shaped plate is arranged on the turning flue part, so that the speed and distribution of smoke in the turning flue part are adjusted, the flow speed and distribution of the smoke in the whole boiler flue are homogenized, and the technical problem of uneven flow distribution in the boiler flue of an existing denitrification system is solved.

Description

technical field [0001] This application relates to the technical field of environmental protection, in particular to a flue and a denitrification system. Background technique [0002] With the increasingly severe environmental situation, all walks of life have begun to pay attention to environmental protection. In the power grid, the combustion flue gas of power plants contains a large amount of nitrogen oxides, which seriously affect the environment. Therefore, denitrification technology has emerged as the times require. [0003] Since the denitrification system was added to the existing power plant, after several optimization tests, preliminary results have been achieved, but it was found that there was a serious uneven flow field in the boiler flue of the existing denitrification system, and the uneven flow field affected the denitrification efficiency. , and the ammonia escape is serious. [0004] Therefore, improving the boiler flue of the existing denitrification syst...
