TWI257994B - Flame generator - Google Patents

Abstract

A flame generator includes a nozzle layer, a flow conduction layer, a diffusion layer, and a flame aperture layer. The flow conduction layer includes a flow conduction blade structure so that air enters in a vortex pattern from the side face for effectively mixing fuel and primary air. The flame aperture layer includes a plurality of vortex units. Each vortex unit includes a plurality of flame apertures interleaved in a ring shape. Furthermore, each flame aperture has an inclination angle so that the fuel/air mixture is sprayed out in a vortex manner to form a vortex combustion type flame and further include secondary air in a vortex effect in order to produce a complete combustion to reduce the formation of CO and hydrocarbons. Meanwhile, a large amount of secondary air entered in a vortex effect for mixing can effectively reduce the local temperature in order to avoid the occurrence of a localized high temperature from damaging the flame generator body, while reducing the formation of nitrogen oxides.
