Abstract
The utilization of flammable wastes in composite fuels for boiler combustion is discussed. The combustible materials considered are coal flotation wastes, long-flame coal, sawdust, and cardboard. These components undergo combustion in the form of a bed of dry mixture or as aqueous suspensions. The following characteristics are determined: the minimum ignition temperature, the delay time of gaseous or heterogeneous ignition, the maximum temperature in the combustion zone, and the calorific value of the fuels. Sawdust-based compositions may be recommended for kindling and to minimize the ignition time. The heat liberation in the combustion chamber may be significantly increased by using mixtures of sawdust, coal slurry or filter cake, and coal dust. The use of such wastes as industrial fuels is very promising.
