Definitions

  • This invention relates to a solide fuel burner according to the first part of claim 1 and has particular, application to burners utilising low grade fuels such as unprocessed peat and pelleted municipal waste.
  • burners there are a number of burners currently available that are capable of burning certain low grade fuels, such burners commonly being of the flat bed type and incorporating moving grates to attempt to avoid the build-up of clinker which inevitably forms an combustion of such fuels. Thus it will be appreciated that such burners are of relatively complex and therefore expensive construction.
  • burners in the form of rotating drums, as for example in GB-A-376491 and GB-A-154353, and to provide means within the drum to feed the fuel along the drum as it rotates, as for example in EP-A-0126619.
  • a solid fuel burner comprising a substantially tubular housing mounted for rotation about a substantially horizontal axis, a source of fuel comprising a hopper supplying fuel to a feeder having an output end, said output end of the feeder supplying fuel to one end of the tubular housing, a source of air under pressure for supplying air to the interior of the tubular housing (12), and means within the housing (12) which, on rotation of the housing, feed the fuel and products of combustion thereof from the one end of the housing towards the other end thereof, characterised in that the fuel is supplied at a controlled rate to the interior of one end region of the tubular housing at a point substantially centrally of the transverse section of the housing, the source of fuel being movable relative to the housing in a direction substantially axially of the housing whereby the position of the output end of the feeder can be varied axially between one end of the housing and a region within the housing axially displaced from said one end such that, in use, the degree of preheating of the fuel within said one end of the
  • the fuel supplied to the burner housing is first of all ignited and combustion air is then fed to the housing to maintain the flame.
  • the rotation of the housing together with the action of the feed means within the housing ensure continuous movement and agitation of the fuel and combustion products thereof within the burner in such a manner as to prevent any clogging of the bed whilst at the same time providing an efficient output therefrom.
  • the degree of preheating of the fuel can be varied to suit the particular fuel, very moist fuel being fed further into the tubular housing than drier fuel.
  • Such a burner is in fact particularly suited to the burning of unprocessed peat which has a high moisture content of up to 60%, sawdust, coal slurry from colliery washing plants and pelleted municipal waste material even with high plastic content, none of which can be burned satisfactorily in convention burners.
  • the walls of the tubular housing have a plurality of apertures therethrough, the burner further comprising an outer sleeve surrounding said tubular member to define an annular chamber between the sleeve and the tubular member, air under pressure being supplied to said chamber and entering the interior of the housing, substantially radially thereof, through the apertures in the tubular member.
  • air under pressure is also supplied through the one end of the housing in a direction substantially axially thereof.
  • the housing comprises a plurality of axially aligned, tubular portions of increasing diameters, adjacent ends of which are located one within the other to provide a substantially continuous housing with annular gaps between said adjacent ends through which air under pressure can be supplied to the interior of the housing.
  • the housing may comprise a spirally wound strip of material with the edge regions of adjacent windings overlapping one another but being slightly spaced from one another in a substantially radial direction, air under pressure being supplied to the interior of the housing through said radial spacings between adjacent windings.
  • the feed means within the tubular housing may comprise one or more helical bars secured to the inner wall of the housing.
  • said feed means may comprise a plurality of fins secured to the inner wall of the housing and spaced substantially helically therearound.
  • the feeder of the source of fuel comprises a rotary screw feeder, the output end of said feeder being positioned at said region substantially centrally of the tubular housing, the rotary screw feeder and the tubular housing being movable relative to one another in a direction substantially axially of the housing whereby the position of the output end of the feeder can be varied axially within the housing.
  • the solid fuel burner comprises drive means for rotating the tubular housing, which drive means conveniently comprises a D.C. motor which may rotate the housing continuously or periodically through predetermined angular steps.
  • said drive means for the tubular housing also drives the rotary screw feeder, control means being provided whereby the drive to the housing and the'drive to the feeder can be varied independently of one another.
  • the illustrated burner comprises a fuel hopper 2 provided in its lower regions with a rotary screw feeder 4 having an output end 6 projecting from the hopper 2.
  • the feeder 4 is driven by a D.C. motor 8 as will be described in more detail below whereby fuel in the hopper 2 can be fed along the feeder 4 to the output end 6 thereof in a controlled manner.
  • the burner further comprises a burner assembly indicated generally at 10 and including a tubular housing 12 or combustion chamber mounted for rotation about a horizontal axis. More particularly, the one end of the housing 12 comprises a gearwheel 14 inwardly of which is provided a plate 16 whereby a chamber 18 is defined between said plate 16 and the gearwheel 14. A plurality of axial apertures 20 are formed through the plate 16 to interconnect the chamber 18 with the interior of the housing 12.
  • a tubular sleeve 22 surrounds the housing 12 to define an annular chamber 24 between said sleeve 22 and the housing 12, the housing 12 being rotatable in substantially sealing relationship within the fixed sleeve 22.
  • a plurality of radial apertures 26 are formed in the wall of the housing 12 to interconnect the chamber 24 with the interior of the housing 12 and with the chamber 18.
  • a fan 28 is connected to an inlet 30 in the sleeve 22 feeding into the chamber 24 whereby air under pressure can be supplied by said fan 28 through said inlet 30 into the chamber 24. Said air under pressure then flows through the radial apertures 26 into the interior of the housing 12 as well as into the chamber 18 and through the axial apertures 20 into the interior of the housing 12 as will be described in more detail below.
  • a pair of helical bars 32 are welded to the interior wall of the housing 12 in the form of an Archimedean screw again for reasons which will become apparent.
  • a horizontal drive shaft 34 extends through the hopper as shown, one end of said shaft carrying a gearwheel 36.
  • a chain 38 interconnects said gearwheel 36 with the output from the variable speed D.C. motor 8 whereby said shaft 34 is driven by said motor 8.
  • An adjustable, eccentric indexing pawl 40 is mounted on the other end of, to be rotatable with, the shaft 34, said pawl 40 co-operating with the teeth of the gearwheel 14 integral with the housing 12.
  • the pawl 40 engages with the gearwheel 14 to effect a predetermined degree of rotation of the housing 12 dependent upon the precise setting of the pawl 40.
  • a further gearwheel 42 is mounted on the one end of the shaft 34 adjacent said gearwheel 36, a chain 44 interconnecting said gearwheel 42 with a gearwheel 46 mounted on the end of, to be rotatable with, the feeder 4 whereby said feeder 4 is driven by the motor 8.
  • a plurality of removable flails or agitators 48 are axially spaced along the shaft 34 to be rotatable with the shaft 34 to agitate the fuel in the hopper 2 as and when necessary.
  • the described burner is conveniently mounted on wheels such as 50 so that the overall apparatus can be mounted on rails and be readily presented to an aperture in the door 52 of a furnace or boiler to which the burner is to be applied.
  • the burner assembly 10 and associated equipment is movable axially relative to the hopper 2 and feeder 4 so that the axial position of the output end 6 of the feeder within the housing 12 can be varied.
  • the described apparatus operates as follows. With fuel in the hopper 2 and with the motor 8 actuated, the feeder 4 delivers fuel from its output end 6 into the interior of the housing 12. This fuel is ignited by applying a flame thereto, and, once established, the fan 28 is actuated to deliver air to the housing 12 to maintain the combustion in the housing.
  • the flame so formed extends from the open end of the housing 12, the air under pressure entering said housing 12 axially thereof through the apertures 20 serving to direct the flame in blow-torch manner from said open end of the housing 12.
  • the rotation of the housing effected by the drive pawl 40 serves to agitate the fuel and products of combustion thereof within the housing 12 thus exposing any unburnt fuel to the incoming combustion air which totally envelopes the fuel and ensures complete combustion thereof.
  • the configuration of the bars 32 is such that the fuel and products of combustion thereof are continuously moved forwards within the housing 12 towards the open end thereof, an ash disposal unit (not shown) being provided below said open end of the housing to collect and dispose of the ash so formed.
  • the type of fuel being used determines the settings of the variable features of the apparatus. If the fuel is very moist, such as unprocessed peat which may have up to 60% moisture content, the output end of the feeder 4 is positioned as shown in the drawing ⁇ i.e. as far into the combustion chamber as possible ⁇ so that the fuel can be preheated and dried prior to ignition.
  • the speed of rotation of the housing 12 is chosen dependent upon the combustion time of the fuel being supplied thereto. Peat, for example, needs time to burn and the housing is therefore rotated relatively slowly, typically one revolution per hour, while coal, being more volatile, needs more agitation and the housing is therefore rotated faster, typically three revolutions per hour.
  • the rotational speed of the feeder 4 supplying the fuel to the housing 12, for a given output from the burner is substantially inversely proportional to the rate of combustion, being slower for volatile fuels such as coal and faster for less-combustible fuels such as peat.
  • the agitators 48 are particularly useful when dust-type fuels such as sawdust and the like are used, the agitators serving to prevent caking of the fuel and bridging of the feeder 4 by the fuel.
  • a burner according to the invention may provide a thermal output equivalent to between 50 and 300 kilowatts.
  • burners according to the invention are particularly suited to low grade fuels that, in conventional flat-bed burners, would produce substantial clinker and clog the grates.
  • fuels include unprocessed peat, rice husks, pelleted municipal waste, lignite, coal washery slurry, straw, wood chips and sawdust.
  • the burner may include an automatic control system to provide optimum operating conditions for the various fuels at the required heat loads, said control system governing the rate of feed of fuel to the burner assembly, the rate of rotation of the housing 12 and the flow of combustion air from the fan 28.
  • the housing 12 may be other than a continuous tubular member and may comprise a plurality of axially aligned, tubular portions of increasing diameters the adjacent ends of which are located one within the other to provide a substantially continuous housing with annular gaps between the adjacent ends of the tubular portions permitting air under pressure to be supplied therethrough to the interior of the housing.
  • the housing may comprise a spirally wound strip of material with the edge regions of adjacent windings overlapping one another but being slightly spaced from one another to enable air under pressure to be supplied to the interior of the housing through the radial spacings between adjacent windings.
  • the feed means within the housing 12 may be other than helical bars and may comprise, for example, a plurality of fins secured to the inner wall of the housing and spaced substantially helically therearound.
  • the helical bars or fins may be replaced by a pair of continuous hollow helical tubes within the housing 12 or by a plurality of hollow tubes spaced substantially helically around the inner wall of the housing, these tubes being provided with a plurality of holes therein.
  • said air is emitted through the holes in the tubes, substantially radially of the housing 12 to improve combustion within said housing, such an arrangement being particularly useful in larger burners with deeper beds therein.
  • the sleeve 22 may be arranged to rotate with the housing 12, while, instead of being index driven in step-like manner by the eccentric pawl 40, the housing 12 may be continuously rotated by a variable speed motor such as 8.
