The component unit (27) has a drive shaft (33), supported in an adaptor sleeve (37), for driving the gasifier (17).

Particularly in the mixing head (29), the evaporated fuel mixes with the combustion air flowing in through the opening (77) and is directed radially to the outside by a deflector (31, 31').

Abstract: Burner for a suspension of fine-grained coal in a liquid, particularly water, which burner operates according to a combination of the rotary burner and toroidal burner principles. The fuel is supplied axially behind a transverse distribution baffle within a conical rotary body. At least the outer rim portion of the inner side of the rotary body forms an angle of 35.degree.-80.degree. with the axis of the burner. At the outer edge of the rotary body there is an annular air supply nozzle for supplying a conically diverging outwardly directed air stream. Outside the air supply nozzle and at a radial distance from it, there is a conical guide baffle (18, 48) which at its outer end may be curved inwardly and which, together with the diverging air stream, serves to produce a positive recirculation of combustion gases, non-combusted coal particles and ash particles in a direction back towards the rotary body in accordance with the toroidal burner principle.

Abstract: The burner has a motor (11), a fuel pump (13) and a fan (15). In the flame tube (81) is a gasification chamber having a gasification chamber housing (75) coaxially located to the flame tube (81), and a housing (75) located at a distance therefrom. The rotor (17) located in the housing (75) can be axially moved with respect to the bearing (29), thereby causing a slot between the axial bearing surfaces (51, 53). Through this slot fuel is ejected into the gasification chamber by the rotation of the rotor (17). The opening of the slot between the axial bearing surfaces (51, 53) depends on the oil pressure which is determined by signals of the heating control 24. The fuel throughput may be controlled in steps or continuously according to the heat requirements. The electric heating (77) is only used during the start phase. In operation of the burner the heat requirements for the gasifying chamber (25) are covered by the recirculation of hot combustion gases through the recirculation gas inlet (73).

Abstract: An improved fuel burning assembly particularly adapted for use with a boiler having a fire box situated below an array of boiler tubes. The assembly discharges a number of spaced rotating streams of minute droplets of a flowable fuel both laterally and longitudinally into the fire box to intermix with a stream of air that is moving rearwardly therein. The fuel air mixture when burning blankets substantially all the boiler tubes with a sheet of flame. Due to such flame contacts substantially all of the boiler tubes are heated uniformly thereby, rather than only a portion of the boiler tubes being contacted by the flame as occurs in a boiler when a conventional burner assembly is used. As a result of the flame distribution and uniform heating of the boiler tubes, an increased thermal efficiency is attained in the operation of the boiler on which the burner assembly of the present invention is used.
