Abstract
A method and apparatus for combustion of fuel wherein in two mutually perdicular air swirls are used. In the cylindrical section of the combustor, a horizontal swirl with respect to the combustor is set in motion. The conical section in conjunction with the cylindrical section forms a vertical swirl with respect to the combustor. Notably, the combustor is not dependent upon orientation in a gravity field.
Claims9
A combustion chamber comprising a lower cylindrical section having an end wall including means to provide a tornado swirl of air axially of the cylindrical section, and a contiguous upper frusto conical section wherein the frusto conical section is fitted with air inlet means spaced about the periphery of the frusto conical section to direct air along the inner wall of the frusto conical section and toward the lower cylindrical section, and the said cylindrical section has air inlet means spaced about its periphery for directing air along the inner wall of the cylindrical section and toward the conical section, and where the larger end of the frusto-conical section is connected to the cylindrical section and where the conical section is open at the smaller end and where a fuel nozzle means is located in the cylindrical section and centrally of the means to provide a tornado swirl of air.
The method of operating a combustion chamber chamber with a fuel burner means and where the combustion chamber has a lower cylindrical base section and an upper frusto conical section comprising the steps of:
- (a) introducing inlet air at the base of the chamber so as to form a tornado swirling effect and (b) introducing inlet air around the circumference of the base of the chamber in an upward direction along the inner wall of the chamber and (c) introducing and forcing inlet air downward along the inner wall of the frusto-conical section so as to form a doughnut swirling effect, and (d) introducing fuel from the fuel burner means axially of the combustion chamber at the base of the combustion chamber.
