Device for improved combustion

摘要

A device for improved combustion of gaseous fuel and air includes a tubular housing and has a combustion chamber disposed about the tubular housing. A first conduit extends from one end of the tubular housing for the passage of air therethrough. A second conduit extends coaxially through the first conduit and tubular housing and has a circular baffle cooperative therewith so as to retard the passage of air. A circular opening in the second end of the tubular housing has an annular baffle disposed therein to assist in retarding flow of air. A series of curvilinear fins are disposed in a spiral configuration between the circular baffle and the annular baffle so as to effect a swirling motion of air passing therethrough. An end cap is attached to the end of the second conduit with a circular baffle at one end of the end cap, an annular baffle at the other end and fins disposed therebetween. Gaseous fuel passes through the second conduit and the end cap. The end cap imparts a swirling turbulence to the gaseous fuel passing therethrough. As a result, a stream of turbulent gaseous fuel is emitted from the end cap and a stream of turbulent air is emitted from the tubular housing. The turbulent air circumferentially surrounds the turbulent gaseous fuel and intermixes therewith so as to form a mushroom shaped flame within the combustion chamber. Substantially complete oxidation of the gaseous fuel is thereby accomplished and noxious waste gases are substantially eliminated.
