SOLID FUEL COMBUSTION PROCESS Russian patent published in 1998 - IPC

FIELD: thermal engineering; combustion of solid fuels including vegetable wastes. SUBSTANCE: process involves feeding primary and secondary air streams to combustion zone as well as secondary air to inlet and outlet of combustion zone in proportion of (0.8-1.42):1.0; proportion of masses of primary and total air is 1;(3.0-68). In addition, heated air is fed to inlet of combustion zone; bin and conveyer are cooled down by some portion of secondary air. Vegetable wastes are burned in furnaces assembled with farm-purpose driers. EFFECT: improved reliability and completeness of fuel combustion, increased service life. 3 cl, 2 dwg, 3 tbl
