Abstract: An apparatus senses the pressure changes in a collector box or relief box of a furnace due to changing wind conditions, and adjusts the gas flow accordingly. The apparatus controls the main gas valve of the furnace through a regulator loop. The regulator loop has a first port that communicates with a chamber below the main diaphragm of the valve, and a second port that communicates with a chamber above the main diaphragm. The regulator includes two diaphragms linked rigidly. A feedback pressure channel is connected to the collector box or the relief box, at one end, and to a feedback pressure tap at the other end. An increase in wind at the furnace vent causes changes in pressure in the collector box and the relief box. This change in pressure is delivered to the feedback pressure tap. When the pressure at the feedback pressure tap increases, the top diaphragm and the bottom diaphragm both move upward.

A nozzle (103), arranged on the head side and on the burner axis (60), for the injection of a fuel is offset upstream at a distance relative to the start of the swirl generator.

Abstract: Method and apparatus for reducing NOx production during air-oxygen-fuel combustion by providing a central core of fuel surrounded by a sheath of oxygen at a combustion end of an air-oxygen-fuel burner. Diametrically opposed air passages are provided on either side of the oxygen sheath to permit entrainment of furnace gases into a flame zone created by primary combustion of fuel and oxygen. Oxygen can be introduced into each air passage to enhance combustion with low NOx emissions.

Abstract: A cooking machine control system for controlling the consumption of fuel by cooking machines, including cooking machines of the type used in restaurant kitchens, such as gas/barbecue broilers, and home cooking machines such as grills, and gas flow valves usable in such cooking machine control systems. The cooking machine control system controls the flow of gas to the burners of the cooking machine to maintain the cooking surface of the cooking machine at an appropriate standby temperature when no food is being cooked, to bring the cooking surface to an appropriate cooking temperature for a predetermined period of time when food is being cooked, and then to return the cooking surface to the standby temperature. In one embodiment, a valve in the gas pipe controls the flow of the gas to provide the desired cooking levels.

Abstract: A furnace control apparatus is described wherein a flow of gas into a burner assembly is directly dependent on an indicia of burner combustion air airflow, such as heat exchanger pressure drop. According to one embodiment of the invention, a first communication fluid line is interposed between a gas valve regulator and a heat exchanger at a first point, and a second communication fluid line is interposed between a gas valve regulator a heat exchanger at a second point. The main valve of the gas valve is responsive to the pressure differential between the first and second points so that a flow of gas into a furnace burner assembly is commensurate with a present flow level of combustion air.
