广东粤华发电有限责任公司#1锅炉是上海锅炉厂设计制造的400t/h中间再热自然循环微正压箱式燃油锅炉。露天布置,炉膛深度和宽度均为8510mm,四周敷设膜式水冷壁,与4根大直径下降管构成12个循环回路,前后左右墙各3个。后水冷壁在标高23.5m处,将炉膛上方分为上行烟道和下行烟道2部分。上行烟道按烟气流向布置Ⅰ、Ⅱ、Ⅲ级过热器及高温过热器。下行烟道按烟气流向布置有低温再热器及省煤器。锅炉采用轻型敷管炉墙,除空气预热器外,锅炉采用全悬吊结构,全部重量由安装在炉顶的钢梁支承,受热面均匀向下自由膨胀。过热器集汽箱位于炉前炉外27m平台上,由5个
Guangdong Yuehua Power Generation Co., Ltd. # 1 Boiler is designed and manufactured by Shanghai Boiler Plant 400t / h intermediate reheat natural circulation micro-pressure tank-type oil-fired boilers. Open-air layout, the depth and width of the furnace are 8510mm, laying around the membrane wall, and four large diameter drop tube 12 loop, front and rear left and right walls of the three. After the water wall at the elevation of 23.5m, the upper part of the furnace is divided into upper and lower flue chimney 2 parts. Upstream flue gas flow direction set Ⅰ, Ⅱ, Ⅲ superheater and high temperature superheater. Downstream flue gas flow direction of the arrangement of a low temperature reheater and economizer. Boiler with light pipe wall furnace, in addition to air preheater, the boiler with full suspension structure, the total weight of the roof mounted by the steel beam support, the heating surface evenly downward downward expansion. Superheater set steam box is located in front of the stove 27m platform, from 5
