The coal ash utilization project of Henan Coal Chemical Group Anhua produced the first batch of products at the end of the week. The product basically met the design requirements from the technical safety of the process to the production process and quality, which symbolized the successful trial production of the project. The Anhua fly ash utilization project can consume about 11 million tons of waste fly ash per year, with an annual output of 250,000 cubic meters of autoclaved aerated concrete block, and can save 151,000 tons of standard coal annually for the company's chemical production. 6.84 million tons, saving about 120 acres of land. For a long time, the company has adopted a large number of carbon-containing fly ash produced in chemical production in a landfill manner, which has resulted in waste of coal ash resources and pollution of the environment. The use of fly ash, boiler waste as raw material to produce autoclaved aerated concrete block new wall materials, can achieve comprehensive utilization of resources.
