我厂于1984年安装投运了一台SHL10-25/400一A型链条锅炉,长期以来,运行状况差,燃烧热效率低,出力不足,锅炉正压运行。这些年来,厂里针对燃烧不良和正压运行状况将立式空气预热器改为卧式空气预热器、尾部烟道多弯地方改为少弯较直而且短的烟道,旋风除尘器改为水膜除尘器,炉膛内粘贴硅酸铝耐火纤维板等,但结果仅正压运行稍有改善,而燃烧状况基本保持原样。 1改进措施为了保证全厂缫丝、织绸及生活用汽和自发电需
Our factory installed and put into operation a SHL10-25 / 400-A type chain boiler in 1984. For a long time, it has poor operating conditions, low thermal efficiency of combustion, insufficient output and positive pressure operation of boilers. Over the years, the factory has changed the vertical air preheater to a horizontal air preheater for poor combustion and positive pressure operation. The multi-bend area at the tail flue was changed to a straight and short flue with less bend. The cyclone Change to the water membrane dust collector, the furnace paste aluminum silicate refractory fiber board, etc., but the results only a slight positive pressure operation to improve, while the combustion remains unchanged. 1 improvement measures In order to ensure the whole plant reeling, woven silk and household steam and self-generating needs
