Abstract
A burner, particularly for use in thermophotovoltaic (TPV) applications, is provided having a fuel distribution tube with integrated swirl vanes adjacent exit holes in the sides of the fuel distribution tube, a ceramic burner cap attached the top end of the fuel distribution tube and a liquid fuel being provided through a fuel feed tube protruding through the bottom end of the fuel distribution tube, thereby forming a burner assembly. The burner assembly fits slidably into a cylindrical burner sleeve which forces primary combustion air through a passage formed between the sleeve and the swirl vanes. The primary combustion air mixes with the fuel in the vanes and burner slot formed between the burner cap and sleeve. The fuel feed tube used to supply fuel to the burner is a heated tube having a small orifice at the burner end. The tube is heated using an internal heater that vaporizes the fuel and can also use recuperated heat from the burner combustion process. The fuel feed tube can include a cleaning needle and a thermocouple for determining the fuel temperature at the orifice for regulation of the heater.Gaseous fuel would merely be introduced through an open-ended tube at the bo…
