power engineering; fluid-bed furnaces for burning solid fuels. SUBSTANCE: device has holes on checker half facing the drain chute their total flow section being 1.05- 2.00 of total flow section of other half of same checker. Such arrangement provides for reliable transport of fluidized-bed noncombustible particles and large lumps of fuel of high specific gravity easily settling on grate to drain chute. EFFECT: provision for eliminating clogging of grate. 3 cl, 5 dwg _
