Properties and Pulverized Coal Combustion of Low-Reactivity Fuels. Part I. Fuel Properties and Preparation for Combustion

Abstract

Low-reactivity properties of anthracite, lean coals, and petroleum coke are determined by a combination of factors, including not only a low heating value of the volatile matter, but also an increase in the volatile yield and ignition temperatures, as well as decrease in reactivity properties of a non-volatile residue. The fuel preparation activities intended to increase the stability of the fuel ignition and burnout include the improvement of heat balance of the air-fuel mixture flow and favorable adjustment of the reactivity properties of the fuel supplied to the furnace.
