METHOD OF PREPARATION FOR BURNING SOLID FUEL

摘要

FIELD: burning solid fuels, bark and waste lumber in industrial heat-power engineering. SUBSTANCE: fuel is subjected to heat to heat treatment in circulating aerofountain layer of reactor; gaseous products of thermal treatment are subjected to after- burning in boiler furnace together with fine particles of fuel entrapped with these products; separated coarse solid fractions of products of treatment of fuel are returned together with air to lower portion of reactor, starting fuel being fed to upper portion. EFFECT: enhanced efficiency.
