Latest Patents
One of Mullens' latest patents is a low NOx combustion system for fuel-fired heating appliances. This invention features a fuel-fired, forced air, draft induced heating furnace equipped with NOx reduction apparatus associated with multiple combustor tubes. The design includes in-shot type fuel burners that are strategically spaced apart from the open inlet ends of the horizontal combustion sections of the combustor tubes. The NOx reduction apparatus consists of several metal mesh tubes that have diameters significantly smaller than the internal diameters of the combustion tubes. These mesh tubes are coaxially anchored to the outlet ends of the burners and extend into the combustion tubes. During operation, the flames from the burners are forced through the mesh tubes, which reduces the cross-sections of the flames, increases their axial velocity, and minimizes the contact of secondary combustion air with the hottest zones of the flames.
