SOLID FUEL COMBUSTION PLANT

摘要

industrial thermal engineering; water and steam boilers. SUBSTANCE: fuel is incompletely burned in precombustion chamber in inert-filler fluidized bed; gaseous products of gasification and carryover small particles are burned up in boiler furnace in secondary-blast jets; their ignition is effected in precombustion chamber; small unburned fuel particles separated in dry bottom hopper are burned up in bottom blast device. EFFECT: reduced heat loss with stack gases, mechanical and chemical incomplete burning. 3 cl 1 dwg
