摘要
火力发电厂烟气脱硝系统是电力生产系统中重要的环境治理设施,脱硝系统运行的稳定性对于周边区域的大气环境保护作用十分巨大。本实例为技术改造,对尿素水解制氨系统产品气管道的保温伴热进行改造,以彻底消除因管路较长,保温伴热效果较差而导致冷凝堵塞的隐患,提高脱硝系统运行的稳定性,降低烟气氮氧化物排放量。
The thermal power plant flue gas denitrification system was an important environmental treatment facility in the power production system. The stability of the denitrification system was very significant for the environmental protection of the surrounding area. This case was technological transformation of reforming the thermal insulation heat tracing of the gas pipeline of the urea hydrolysis and ammonia plant system for completely eliminating the hidden dangers of condensation jam due to the long pipeline and poor thermal insulation heating performance, improving the stability of the denitrification system operation, and reducing the emission of nitrogen oxides from flue gas.
