Abstract

The invention discloses an industrial solid waste constant energy environmental-protection fuel containing calcium carbide furnace dust, calcium carbide slag, fly ash and a reductant-oxidant, wherein based on 100 parts by weight of the calcium carbide furnace dust, the content of the calcium carbide slag is 72-200 parts by weight, the content of the fly ash is 35-85 parts by weight, and the content of the reductant-oxidant is 30-85 parts by weight. A large amount of industrial solid wastes can be consumed per year, the prepared industrial solid waste constant energy environmental-protection fuel has the advantages of full combustion and high calorific value, and the calorific value is more than 40 MJ / kg and is obviously increased compared with that of standard fire coal. At the same time, the fuel also has the characteristics of cleanness, environmental protection and low cost, can be used as a fire coal substitute for use in coal-fired boilers, overcomes the recycling problem of a large amount of industrial solid wastes in the prior art, and besides, creates economic benefits.

Description

technical field [0001] The invention relates to the field of environmentally friendly fuels, in particular to an environmentally friendly industrial solid waste solid energy fuel. Background technique [0002] Industrial solid waste refers to solid waste such as mining waste rock, mineral processing tailings, fuel waste residue, smelting and chemical process waste residue discharged during industrial production, including tailings, coal gangue, fly ash, mirabilite, calcium carbide slag, smelting slag, Solid wastes such as by-product gypsum and red mud are listed as bulk industrial solid wastes. During the "Twelfth Five-Year Plan" period, the total volume of bulk industrial solid waste in my country is expected to reach 15 billion tons, with a net increase of 8 billion tons in stockpiling, and a total stockpiling of 27 billion tons. 400,000 mu of land. A large amount of industrial solid waste that has been accumulated in our country and is newly generated every year not only...
