Investigation for a Sustainable Use of Fossil Coal through the Dynamics of Interaction of Smokeless Solid Fuel with Oxygen

Abstract

One of the ways to solve the problem of environmental protection in the fuel/metallurgical sectors of the economy is the introduction of new complex technological processes, which can be implemented by the principle of energy-chemical-technological processing of carbon raw materials. It involves the extraction of valuable chemical components in the form of coke oven gas, benzene hydrocarbons, hydrogen sulphide, coal tar, ammonia, as well as the production of solid product with new properties.

A technology for the production of smokeless solid fuel from a mixture of gas coal (80%) and coal wastes (20%) has been developed. Comparative studies of the kinetics of combustion have been carried; the dependence of the rate of interaction of coke residues of anthracite, highly metamorphosed coal (Vdaf=11.1%), low-metamorphosed coal (Vdaf =41.6%) and smokeless solid fuel (Vdaf=2.7%) with oxygen of air was obtained. The characteristics of anthracite, high-metamorphosed coal, low-metamorphosed coal and smokeless solid fuel combustion dynamics are obtained, which allow further determination of the reactivity of the carbonaceous substance of the fuel.

The developed technology of production of smokeless carbon fuel offers the opportunity to use carbon wastes and improve environmental performance. According to the results of industrial experiments, the optimal quality indicators of smokeless solid fuels recommended for ferroalloy industries were established at ferroalloy enterprises.
