Low pollutant-high thermal efficiency burner
Abstract
Abstract A liquid-fired burner in which the combustion space is defined by a cylinder which includes a screen heated by radiation from the combustion flame and by convection from the combustion gases flowing through the screen. The screen loses heat to the ambient volume principally by radiation and maintains an equilibrium temperature equal to or lower than the gases within the combustion space. Complete combustion with minimum excess air and low pressure drop is thus achieved resulting in operation at high thermal efficiency with minimal pollutant production. The radiant screen is so woven that very few optical paths exist from the interior combustion space to the ambient volume. Substantially all radiant energy originating in the combustion flames is intercepted by the screen, and the woven pattern serves also to enhance the transfer of heat to the screen from combustion gases passing therethrough. The screen may be made of an oxidationresistant alloy or may in some instances be coated with high temperature ceramic.
