漳平电厂10吨/时全沸腾炉自投产以来,已连续运行较长时间,操作技术也有了改进。但因飞灰损失严重,煤耗仍高达1.2公斤/度。为了解决这一问题,该厂进行加装小飞灰床的改进。小飞灰床的位置在主床后面而紧靠主床,其标高比主床略低。小飞灰床的布风板面积为2.3米~2,冷态风速为0.3～0.4米/秒。床内布置12米~2倾斜角为23.5度的全浸式受热面。风帽节距为120×120毫米,帽头直径为76毫米,风帽小孔直径为5.2毫米。小飞灰床采用单独鼓风,风量约5000米~3/时,风压450毫米水柱左右。由第二燃烧室和多管式除尘器落下汇集在集灰箱的飞灰,以二条绞龙输入小飞灰床底部
Zhangping Power Plant 10 tons / hour full boil-off furnace since its inception, has been running for a long time, the operation of technology has also been improved. However, due to serious loss of fly ash, coal consumption is still as high as 1.2 kg / degree. In order to solve this problem, the plant to improve the installation of small fly ash bed. Small ash bed position behind the main bed and close to the main bed, the elevation slightly lower than the main bed. Small fly ash bed cloth area of 2.3 m ~ 2, cold wind speed 0.3 ~ 0.4 m / s. Bed layout 12 meters ~ 2 tilt angle of 23.5 degrees immersed heating surface. Hood pitch 120 × 120 mm, the head diameter of 76 mm, hood hole diameter of 5.2 mm. Small fly ash bed with a separate blast, the air volume of about 5000 meters ~ 3 / hour, the pressure of about 450 mm water column. By the second combustion chamber and the multi-tube precipitator ash collection ash collected in the ash, with two auger input small fly ash bed at the bottom
