or secondary fuel processor fuel thereafter enters into the main processing chamber 18 as it enters into main processing chamber 18 the air fuel mixture is already experiencing a vortical flow and will rotate about cone shaped member 34 additional ambient air a is also allowed to flow into the secondary or main processing chamber 18 by passing initially through apertures 41 in the housing and subsequently through exterior tangential apertures 42 which extend through the housing wall 40 the initially processed fuel air mixture is further processed in the primary fuel processing chamber 18 the fuel is processed in the secondary or main fuel processing chambers 1 8 substantially the same as it is with respect to the initial fuel processing chamber 16 indeed it is to be understood that one of the fuel processors may be utilized alone without additional fuel processors alternatively more than two fuel processors may be utilized in a series to achieve the desired fuel air breakdown or homogenization ultimately fuel passes through outlet 50 fig5 and into the combustion chamber 20 fig2 where an igniter 21 such as a spark plug ignites the processed fuel and a flame results which is held by the flame holder 22 heat is allowed to escape via apertures 52 formed in the cone shaped flame holder 22 the fuel air mixture passing through outlet 50.
