Burner, in particular burner for the combustion of liquid fuel in the gaseous state
First Claim
1. A burner comprising a motor (11) to drive a fan (15) and a fuel pump (13);
- a gasification chamber (25) formed by a housing (75), said gasification chamber (25) being provided with at least one heatable wall;
rotatable means (17) located in the gasification chamber (25), said rotatable means (17) having a drive shaft (19) coupled to the motor (11); and
a sleeve (23) enclosing the drive shaft (19) and serving as fuel supply means into the gasification chamber (25);
characterized in that a first axial bearing surface (51) is provided by the end of the sleeve (23) located proximate to the gasification chamber (25), that the rotatable means (17) provides a second axial bearing surface (53), and that actuating means (55,
57) are provided to move the two axial bearing surfaces (51,
53) apart from each other or toward each other to supply fuel into the gasification chamber (25) according to the heating requirements, or to stop fuel supply.

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).
