总结：粉煤灰是我国排放量较大的工业废弃物之一，随着电力工业的发展，燃煤粉煤灰排放量不断增加，

粉煤灰是我国排放量较大的工业废弃物之一。随着电力工业的发展，燃煤电厂粉煤灰排放量逐年增加，因此，粉煤灰的危害也威胁着社会生态环境的可持续发展。近日，笔者从媒体获悉，原本是废物、备受诟病的粉煤灰，在一座百万千瓦超超临界燃煤电厂的综合利用中，变垃圾为宝，不仅不再污染周边环境，还创造了良好的经济价值。

据了解，粉煤灰是煤在燃烧过程中产生的固体废弃物。在中国，由于煤电厂数量众多，粉煤灰已成为工业固废的单一污染源，年排放量超过3亿吨。然而，目前中国有许多方法和措施可以实现粉煤灰的再利用。例如，中国华能裕华电厂努力引进一批国际先进的生产设备，将粉煤灰转化为建筑材料。在过去两年中，华能裕华电厂对粉煤灰的综合利用量达到1,206,800吨，相当于节省了950,600吨水泥，节省了2.11亿元的原材料成本，向大气中排放了774,400吨二氧化碳，节约了301.7亩土地。取得了良好的社会和环境效益。

该系列磨机设备可以将飞灰加工成不同颗粒大小的细粉。特别是， 雷蒙磨 equipment has a three-dimensional structure, a small footprint, a complete set of products, uniform fineness of the finished powder, and a 99% pass-through rate. The fly ash can be processed into the building materials field. The processed fly ash can be blended with an appropriate amount of gypsum, and a certain amount of aggregates such as cinder or water quenched slag can be added, and formed after processing, stirring, digestion, wheel milling, compression molding, atmospheric pressure or high pressure steam curing. a wall material; sintered fly ash brick, using fly ash, clay and other industrial waste as raw materials, processed by raw materials, stirred, formed, dried, and fired to form bricks; autoclaved to produce foamed fly ash insulation Brick, a kind of new type of thermal insulation brick with fly ash as the main raw material, adding a certain amount of lime and foaming agent, after mixing, stirring, burning and autoclaving; using fly ash as raw material, adding appropriate amount of quicklime, cement, gypsum and aluminum powder, mixed with water and slurry, injected into the mold to form a porous lightweight building material; Fly ash ceramsite, with fly ash as the main raw material, mixed with a small amount of binder and solid fuel an artificial lightweight aggregate made by mixing, pelletizing, and high temperature cooking.
