FIELD: mechanical engineering; combustion of solid fuel in dense layer. SUBSTANCE: invention can be used in furnaces of solid fuel heat generators, steam and water heating boilers, etc. Proposed fire grate contains plate made with spaces and through holes to pass air. Plate of fire grate is made with free cross-section area-ratio of summary area of all spaces and holes to pass air to entire area of grate (area of burning layer surface) equal to 0.3-3%.
