Abstract Unlike traditional combustion concepts in which the flame is anchored via either swirl and/or bluff body stabilization techniques and the principal mode of heat transfer to the incoming cold charge is via conduction, within the porous ceramic flame holder, additional heat transfer mechanisms are at play to enhance the incoming enthalpy of the reactants to create "excess enthalpy burning" (Min, 1991; Hackert, 1999). Recirculating heat to the incoming mixture without more traditional means as external Flue Gas Recirculation (FGR) extends the flammability limits for superior turndown with emissions compliance, promotes greater flame stability and enables the burner to be a technology enabler for opportunity fuels (low BTU fuels or the like) which may exhibit wide fluctuations in Wobbe Index and other key chemical characteristics (chemical constituents, flame speed, autoignition delay times, etc.). Further and more importantly, the porous ceramic burner radiates more effectively than a conventional flame due to its ability to emit as a black body, rather than in distinct spectral regimes as with traditional flames. The net effect is a system with higher combustion and thermal efficiencies, wider operating envelops and ultra-low emissions performance, all in a highly compact and cost effective package. Seattle based ClearSign Combustion Corporation has pioneered and commercialized this innovative and disruptive technology, referred to as Duplex Technology and has routinely demonstrated sub-5ppm NOx and CO simultaneously in industrial applications and installations.
