| 摘 要： | 北仑电厂2号锅炉低负荷时省煤器出口烟温过低,不能保证机组的脱硝投运率,通过省煤器的分级改造,提高了SCR入口烟气温度,既满足了脱硝设备的烟温要求,又不影响锅炉热效率,为国内同类机组脱硝改造提供了借鉴.

| Abstract: | At low load, the oulet gas temperature in Beilun 2# boiler economizer is too low to guaran- tee the denitration commissioning rate of the unit. Whereas, classification and reconstruction of econ- omizer is able to enhance SCR inlet gas temperature and meet gas temperature requirement of deni- tration equipment, which can provide references for denitration reconstruction of similar unit in China without influences of boiler thermal efficiency. |
