Abstract RU 2343347 C1

FIELD: heating systems.

SUBSTANCE: invention refers to heat engineering and can be used at thermal power stations in slag-tap removal boilers. Furnace consists of a central combustion chamber and at least one periphery combustion chamber with a burner device lead inside periphery combustion chamber through the walls. Burner device consists of coaxial nozzles which supply fines and air and are lead coaxially inside coaxial circulating pipe and burner tip, thus forming annular gaps which form a turning assembly arranged behind external walls of periphery combustion chamber in a cold zone. At that circulating pipe and burner tip have the possibility of synchronous axial turning and longitudinal axial displacement relative to fines and air supplying nozzles as well as periphery combustion chamber walls wherethrough they are lead, at that between circulating pipe and burner tip there installed are radial plate inserts, and circulating pipe and burner tip are knee- and arc-shaped.

EFFECT: providing the boiler lighting-up, and after that the possibility of back up firing of the above-bottom space of central combustion chamber in order to improve efficiency of molten slag flow.
