1. A burner for fluid fuel comprising:
- a body defining a bore open at both ends, said bore having, sequentially in the direction from one of said open ends to the other of said open ends, a first frusto-conical portion of increasing cross sectional area in said direction, a cylindrical portion and a second frusto-conical portion of decreasing cross sectional area in said direction, said body further defining an annular chamber surrounding said bore;
inlet means to said chamber, and outlet means from said chamber surrounding said bore and opening into said bore in the region of the junction of said cylindrical portion with said first frusto-conical portion and arranged to discharge fuel along the surface of said first frusto-conical portion to its open end;
means for supplying fluid fuel to said inlet means to said chamber; and
air guide means in said bore comprising a body having a cylindrical mid-portion and tapering end portions extending co-axially of said bore with a tapering portion being in said first and second frusto-conical portions and said cylindrical mid-portion being in said cylindrical portion of said bore;
wherein, in operation, fluid fuel and air mixture is burnt adjacent said one end of said bore, air being drawn into said bore from said other end, and drawing fluid fuel from said chamber through the opening of said outlet means.

Abstract
A burner for burning crude or contaminated oil comprises a body defining a bore open at both ends, at one of which the oil is burnt, air being drawn into the flame through the bore, and an annular oil inlet in the bore wall such that air flowing through the bore to the flame will draw oil from the inlet in atomised form, will mix with it and will carry it into the flame. The burner is surrounded by an annular water ring provided with nozzles for spraying water into the flame.

17. A burner for fluid fuel comprising:
-
a body having a bore open at both ends through which air flows and adjacent one of which fluid fuel will be burnt, said body comprising a first part in part defining said bore and a second part which in part defines said bore and is axially slidable relative to said first part of said body, said body further including a chamber for fluid fuel defined between said first and second parts, said chamber having an inlet for fluid fuel and an outlet opening into said bore between said first and second parts, and a radial wall provided by a radially outwardly extending surface on said second part such that the pressure of fluid in said chamber will exert on said radial wall a force urging the second part of said body relative to the first part of said body in a direction to increase the axial extent of said outlet opening;
biasing means for moving said second part in a direction to decrease said axial extent of said outlet opening; andair guide means in said bore; said bore immediately upstream relative to the direction of air flowing therethrough of said outlet opening being cylindrical and immediately downstream of said outlet opening being gradually reduced in diameter, and said air guide means comprising a body co-axial with said bore and extending into said cylindrical and reduced portions of said bore, said body of the air guide means having a tapering portion extending into said gradually reduced portion of said bore. - View Dependent Claims (18, 19, 20, 21)
