某电厂1#机组锅炉为北京巴威公司设计的超临界参数锅炉。锅炉型号为:B&WB-1903/25.40-M,螺旋炉膛、一次中间再热、平衡通风、固态排渣、全钢构架、露天布置的直流锅炉,锅炉配有带循环泵的内置式启动系统。1#机组已运行超过4年时间。上次检修期间对该锅炉结垢量进行了检测,检测结果水冷壁管向火侧结垢量达276g/m～2,背火测垢量198g/m～2,省煤器管垢量354g/m～2。据此估算,目前水冷壁结垢量将超过300g/m～2,达到《火力发电厂锅炉化学清洗导则》规定的
A power plant boiler unit # 1 for the Beijing Bayei company designed supercritical boiler parameters. The boiler models are: B & WB-1903 / 25.40-M, a spiral hearth, an intermediate reheat, balanced ventilation, solid slagging, all-steel frame, open-air boiler with built-in start-up system with circulation pump. Unit 1 has been in operation for more than 4 years. During the last overhaul, the amount of fouling of the boiler was tested. The test results showed that the amount of scale fouling on the fireside reached 276g / m 2, that of backfire was 198g / m 2, and that of economizer 354g / m ~ 2. Based on this estimate, the current scale of water wall fouling will exceed 300g / m ~ 2, to “thermal power plant boiler chemical cleaning guidelines” provisions
