一台60t/h煤粉工业锅炉的设计和试运行

Design and Running Test of a 60 t/h Pulverized-coal-fired Industrial Boiler

以一台试运行的60 t/h煤粉工业锅炉为案例,介绍该煤粉工业锅炉的结构特点、燃烧器配置和试运行效果。经168小时试运行表明,该煤粉锅炉负荷调节能力强,可在30%~120%负荷范围内稳定运行;烟气排放环保,仅采用SNCR脱硝工艺,烟囱出口处的NO_(x)排放在100 mg/m^(3)(标态)以下,平均值为76.43 mg/m^(3)(标态)。

Taking a 60 t/h pulverized-coal fired industrial boiler as an example,the boiler structural characteristics,burner configuration and its operation effect were introduced.The 168-hour running test showed that the boiler has a strong adaptability of load variation from 30%to 120%of the rated load,and is environmentally friendly,NO_(x) emission at the outlet of the chimney was lower than 100 mg/m^(3)(standard state)with the average of 76.43 mg/m^(3)(standard state)when only SNCR technology was used in the period of 168-hour running test.
