利用烟灰内燃烧砖,可节约很多粘土和煤炭,且使热电厂排出的废料-烟灰得到充分利用。北京市太平庄砖瓦厂双桥车间利用北京热电厂烟灰内燃烧砖获得了较好的效果,现介绍于下:一、烟灰脱水和发热量的测定热电厂的烟灰颗粒细而松散,含水量较高(约18～29%),因此,必须经过脱水。双桥车间将进厂烟灰堆放数日,经自然干燥,使水分降至17～18%以后才用于 The use of internal combustion bricks in soot can save a lot of clay and coal, and make full use of the waste - soot discharged from thermal power plants. The double-bridge workshop of Beijing Taipingzhuang Brick and Tile Factory has obtained good results from the use of internal combustion bricks in the thermal power plant of Beijing Thermal Power Plant. The results are as follows: I. Determination of soot dehydration and heat generation Soot particles in thermal power plants are fine and loose, with high moisture content. (About 18 to 29%), therefore, must be dehydrated. The Shuangqiao workshop puts the soot into the plant for several days, and it is naturally dried to reduce the moisture to 17 to 18% before it is used.
