我厂6号锅炉是上海锅炉厂1959年制造.1965年安装投产的65t/h单汽鼓自然循环水管抛煤链条炉。1980年5月首次改为中间储仓式煤粉炉.燃烧方式为两侧墙对冲旋流喷燃悬浮燃烧,额定汽压为3.82MPa,过热汽温为450℃。因煤质多变,无法满足旋流式燃烧器所需要的煤种,加之原结构不合理,运行中燃烧不稳,负荷带不足,热损失较大,运行热经济性极差。因上列原因,1991年中报退役改造。改造后的锅炉额定蒸发量为70t/h,最大蒸发量为
Our No. 6 boilers are manufactured by Shanghai Boiler Works in 1959. The 65t / h single-booster natural circulation water pipes thrown into coal-fired chain furnaces were put into operation in 1965. It was first converted to an intermediate storage pulverized coal fired furnace in May 1980. The combustion mode was a two-side wall hedge-swirling combustion suspension combustion with a rated steam pressure of 3.82 MPa and a superheated steam temperature of 450 ° C. Due to the variety of coal quality, it is unable to meet the requirements of the cyclone type of coal, combined with unreasonable original structure, unstable combustion during operation, insufficient load belt, large heat loss and poor thermal economy. Due to the above reasons, the mid-year report retired in 1991. After the transformation of the boiler rated evaporation of 70t / h, the maximum evaporation
