炉底煤灰的生产和品种美国用煤作燃料的发电厂生产出两种不同的炉底煤灰(以下简称“底灰”——译注)。一种是湿底灰或称湿炉渣,是在溶融状态下从炉内排出进入水箱里产生的。炉渣经水淬后形成一种玻璃状的多角形材料,粒径大都为0.5～5毫米。另外,由于炉内的结渣作用(或固结作用),还生产出一种蜂窝状的粗粒料(大于或等于5厘米)。 Bottom Ash Production and Variants Coal fired power plants in the United States produce two different furnace bottom ash (hereinafter referred to as “bottom ash”). One is wet bottom ash or wet slag, which is discharged from the furnace into the tank in a molten state. Slag by water quenching to form a glassy polygonal material, most of the particle size of 0.5 to 5 mm. In addition, a honeycomb-like coarse aggregate (greater than or equal to 5 cm) is also produced due to slagging (or consolidation) in the furnace.
