       12 . A method of reducing carbon monoxide (CO) and oxides of nitrogen NOx emissions, comprising the steps of:
 positioning a burner head nearer a first open end of a combustion cylinder surrounding said burner head than a second open end, so that a naturally aspirated, unregulated, turbulent forced air effect develops;   combusting an air/fuel mixture exiting from said burner head between said burner head and an inner wall of said combustion cylinder;   discharging the combusted fuel from said second end of said cylinder;   using the forced air effect to increase a pressure at air inlets of said burner head to reduce CO and NOx emissions due to the increased pressure.
