Latest Patents
One of Grahl's notable patents is the "Low NOx combustion system for fuel-fired heating appliances." This invention involves a fuel-fired, forced air, draft induced heating furnace equipped with NOx reduction apparatus associated with a plurality of combustor tubes. The design features in-shot type fuel burners that are strategically spaced apart from the open inlet ends of horizontal combustion sections of the combustor tubes. The NOx reduction apparatus includes metal mesh tubes that are significantly smaller in diameter than the combustion tubes. These mesh tubes are coaxially anchored to the burners and extend into the combustion tubes, enhancing the efficiency of the combustion process. During operation, the flames are forced through the mesh tubes, which reduces their cross-sections, increases their axial velocity, and minimizes the contact of secondary combustion air with the hottest zones of the flames.
