  • Publication number: 20100330518
    Abstract: A heat engine can have a fuel selector valve for selecting between a first fuel and a second fuel. Making the selection with the fuel selector valve can also determine a flow path through the heat engine, there being two different paths, each configured for a different fuel. A burner nozzle can form a single unit with the fuel selector valve. In some embodiments the burner nozzle can also form a single unit with an outlet valve.

  • Patent number: 7815875
    Abstract: The invention relates to a device for the reactive conversion of gaseous streams at high temperatures in excess of 1000° C. Said device comprises a reaction chamber (8) with an inlet opening for the gaseous streams to be converted, in particular a burner head (2) and an outlet opening for the converted gaseous streams. In order to guarantee the highest possible conversion performance, the reaction chamber (8) has a narrow construction, extending longitudinally from the inlet opening to the outlet opening to form a controlled gaseous flow, thus preventing a circulatory flow in the reaction chamber (8). To achieve reaction conditions that are as adiabatic as possible, the reaction chamber (8) is thermally insulated with a layer (7) that has a porous foam and/or fiber structure. In the simplest embodiment, the reaction chamber (8) is cylindrical, thus achieving a tubular flow reactor construction for the entire device.

An outlet direction (R) of the fuel/air jets from the burner and the direction (A) of the exhaust gas channel cross each other. Hence, the burner introduces fuel parallel or at an angle to the wall into the furnace chamber where the burner is mounted for flameless oxidation of the fuel.

  • Patent number: 6887073
    Abstract: A damper for a burner includes a gate plate that moves generally parallel to the inlet of a blower housing of the burner. The gate plate rotates parallel to the inlet and is sized and positioned so that it can rotate between a position completely covering the inlet and a position leaving the inlet completely uncovered. A seal assembly between the gate plate and the inlet substantially seals a gap between the gate plate and the inlet. An actuator moves the gate plate automatically to close the damper or open the damper to any of a plurality of open damper positions.

  • Publication number: 20040209212
    Abstract: A low gas flow in-line orifice assembly adapted for use with a gas-fueled device is disclosed. The orifice assembly comprises an elongate body formed about a longitudinal axis with a first end and a spaced second end. A bore is defined within and extends in the lengthwise direction of the body. An orifice is positioned within the bore, and is sized and shaped to meter the gas flow passed therethrough and to also at least partially induce the condensation of any condensates, vapors, aerosols, or entrained particulates that may be present in the gas flow, upstream of the orifice. The body of the orifice assembly is constructed and arranged to be removably placed in fluid communication with a gas supply line feeding the device. A removable filter cartridge may also be positioned within the bore upstream of the orifice, as desired.

    Abstract: A method of combustion and a burner assembly wherein at least one fuel and at least one oxidizer are injected separately. The oxidizer comprises a primary oxidizer stream and a secondary oxidizer stream. The primary oxidizer stream is divided into at least two portions. One portion is injected close to the fuel whereby generating a first incomplete combustion. The second portion is injected downstream of the first injection point with the fuel source consisting of the remaining uncombusted fuel of the first incomplete combustion in addition to the fuel. The secondary oxidizer stream is injected downstream from the primary oxidizer stream, whereby resulting in combustion with the unreactive fuel gases remaining from the first combustion.

  • Patent number: 6767205
    Abstract: A torch and mount assembly wherein the torch, which has a plurality of gas receiving nipples is carried in a housing through which it extends. The housing has a plurality of walls forming a substantially air tight enclosure. In at least one wall of the housing are one or more leakproof fittings which are connected to similar leakproof fittings for the nipples by means of preferably flexible gas conduits within the housing. In the system, gaseous mixtures are applied from a source or sources to the fittings in the housing wall remote from the high temperatures of the torch, while the conduits within the housing are protected from mechanical and thermal stresses. An inert gas from a suitable source is introduced under pressure into the interior of the housing to reduce leakage from the torch into the housing. The atmosphere within the housing is heated, and the constituents of the housing atmosphere are monitored to aid in detecting leakage.

  • Patent number: 6755355
    Abstract: A coal gasification nozzle is disclosed having a barrier, integral with the face of the injector, that fits into a groove of a heat shield attached to the nozzle face. The barrier prevents oxidative corrosion of the shield, and subsequent damage to the underlying face of the feed injector, by preventing diffusion of corrosive species to the threaded ring by which the heat shield is attached to the face of the nozzle. The life of the injector, and thus the length of any single gasification campaign, is thereby extended.

  • Patent number: 6688881
    Abstract: A torch and mounting system therefor has a cylindrical main glass tube surrounded by a tough and rigid tube. The metallic tube is threaded at each end for receiving compression nuts, each having a ferrule such as an O-ring or a tapered ring inside. Each ferrule is a slip fit over the main glass tube and has an angled surface that butts against the end of the metallic tube. When the nuts are tightened, the sloped surfaces of the ferrules force the ferrules against the main glass tube, thereby fixing it in place within the metal tube. The metal tube in turn is clamped by a mounting clamp which is, in turn, mounted to an adjustment stage for optimum positioning of the torch. A support rail has adjustably mounted thereon one or more strain relieving clamps for holding gas or vapor delivery tubes in place to insure proper delivery of gases and vapors to the torch.
