    Abstract: This invention describes a furnace system for the reduction of nitrogen oxide containing gases which utilizes a two-chambered refractory lined furnace. Fuel gas and stoichiometric air is introduced into the first chamber to provide an ambient temperature sufficient for the reaction of steam and hydrocarbon gases which are introduced into the first chamber to provide a reducing atmosphere. The nitrogen oxide (NOx) containing gases are also introduced into the first chamber where the NOx is reduced. The gases then pass into the second chamber where they are rapidly cooled to a temperature below that at which there is thermo-regeneration of nitrogen oxides. Additional air is supplied to the second chamber for the combustion of combustible gases remaining therein after reduction, care being taken that the temperature never rises above the temperature at which there is substantial regeneration of nitrogen oxides.

    Abstract: This abstract describes a burner system in which gas is flowed into a combustion chamber through a water barrier in such a way that the gas is forced to bubble up through the overlying water through perforations in a horizontal plate. The gas proceeds as a series of isolated bubbles without having a continuous flow channel, thread or column of gas, so as to prevent the flash back of a flame front from the combustion chamber to the source of gas. The apparatus comprises essentially three parts. In the lower part is the water seal structure which comprises a shallow tank of water communicating through its bottom plate to a source tank of water. The gas is introduced under pressure through the water seal by passing downward through an annular passage surrounding the water seal tank. The gas enters the water seal tank through a series of perforations on the circumference near the bottom of the tank and is forced to bubble up through perforations in a horizontal plate, and up to the surface of the water. The gas then passes upwardly through a central cylindrical passage where it meets air at the top of the passage. The air is drawn into the bottom of a cylindrical column or tower which supports the water lock apparatus and permits air to enter the bottom of the tower and pass through an annular space around the combustion chamber apparatus, and to meet and mix with the rising gas column. The mixture is ignited by a pilot flame. The gas mixture then burns and passes upwardly through ceramic covered portion of the tower to whatever apparatus to utilize the hot gases or to the atmosphere.
