FIELD: power engineering; municipal services.
SUBSTANCE: invention relates to the field of municipal energy, in particular to boiler equipment. Solid-fuel fire tube boiler comprises screw feeder-fuel mixer, horizontal cylindrical tank filled with boiler water, flame tube, cylindrical fire rotary chamber, slag shaft, a nozzle system for supply and distribution of air, smoke tubes and a pendulum-type shuffling plate system, wherein the fuel feeder-mixer is arranged in the boiler water volume under the flame tube horizontally with the unit for passage through the boiler rear wall and the slag shaft, it ends at front wall of flame tube by stoker (unloader) in form of reverse helical turn, and by its upper open part feeder-mixer communicates with fire space of flame tube along its lower generatrix.
EFFECT: invention is intended for forced combustion of solid lump fuel in a fire tube boiler, including for combustion of coal scabs, and also for operation in conditions of Far North.
