FIELD: heat power engineering. ^ SUBSTANCE: boiler plant comprises furnace with fluidized layer of fuel and inert filler above the air distributing grate and separating space provided with evaporating shielded heating surfaces and downwelling and upwelling convective gas ducts with an air heater. The boiler plant is made of two-row members separated from each other by a shield and comprising bottom and top furnace sections. Additional evaporating surfaces and surfaces for heating vapor are arranged in the layer of the fuel and inert filler above the air distributing grate. The upwelling convective gas duct receive an economizer. The separating spaces of the bottom and top furnace sections of the unit are interconnected with the upwelling and downwelling convective gas ducts which are connected through the intermediate gas duct with the downwelling convective well provided with the air heater. ^ EFFECT: expanded functional capabilities. ^ 1 cl, 1 dwg |
