Claim:
A combustor ( 10 ) employable for performing a mainly convection heating function in serving as thermo kinetic energiser comprising a combustion chamber ( 12 ) extending regularly about a central axis ( 14 ) and having an axially extending side wall ( 26 , 64 , 66 ) of which at least part of is formed with an array ( 22 ) of fuel charging orifices ( 28 . 1 ) and an array ( 24 ) of air charging orifices ( 28 . 2 ) each facing inwardly at a similar slanted angle to supply fuel and air into a common combustion zone along the combustion chamber ( 12 ) with the openings of the fuel charging orifices ( 28 . 1 ) standing in the side wall in an opposing relationship to those of the air charging orifices ( 28 . 2 ) to achieve an effective combustion reaction, a progressively constricted combusted medium discharge nozzle ( 16 ) at the discharge end for accelerating the discharge velocity of combusted medium, and a combustion fuel supply chamber ( 20 ) and air supply chamber ( 18 ) opening respectively into the fuel charging orifice array ( 22 ) and the air charging orifice array ( 24 ) each being connected to a cooperating fuel supply orifice array ( 50 ) and an air supply orifice array ( 60 ) of the relevant medium, whether fuel or air, while the combustion chamber ( 12 ) is exposable to igniting means ( 34 ) for igniting a combustible mixture once the combustor is in use; said combustor further characterised in that the effective cross sectional orifice area of the plurality of cooperating orifices ( 28 ) of the orifice arrays ( 22 , 24 ) is adjusted by means of an adjustment mechanism ( 30 , 44 , 46 , 48 , 58 , 68 , 70 , 76 ) including a slideable cover ( 58 , 30 ) disposed intermediate the side wall ( 26 , 64 , 66 ) of the combustion chamber ( 12 ) and at least one of the fuel supply chamber ( 20 ) and air supply chamber ( 18 ), said cover formed with an array of fuel supply orifices and an array of air supply orifices, said orifices having an array pattern similar to the respective combustion chamber fuel and air supply arrays, whereby slidably adjusting the extent of the overlap of the respective orifice arrays of the appropriate medium charging orifice array ( 22 , 24 ) though the independent adjustment of the fuel or air supply cover arrays in the relevant cover.
