炉下灰是热电厂排出的一种废渣,处于电厂锅炉炉底及排灰道的前部,故又称为炉底灰,它比粉煤灰的颗粒粗,其颗粒组成类似于天然砂。用它代替人造轻砂配制全轻混凝士,不仅能获得较好的技术经济效果,而且变废为宝,对保护环境、保持生态平衡起到积极作用。我们曾用辽宁电 Furnace ash is a kind of waste residue discharged from a thermal power plant. It is located at the bottom of power plant boilers and the front of the ash discharge path. It is also called bottom ash, which is coarser than fly ash particles and its particle composition is similar to that of natural sand. Using it instead of man-made light sand to formulate full-light condensors, not only can obtain better technical and economic results, but also turn waste into treasure, playing a positive role in protecting the environment and maintaining ecological balance.
