  • Patent number: 8776528
    Abstract: The disclosure relates to a method for operating a gas turbine plant which is supplied with a fuel gas via a compressor station. The compressor station includes a compressor which compresses the fuel gas which is fed via a gas feed line and delivers it via at least one control valve to a combustion chamber of the gas turbine plant. A bypass system is arranged in parallel to the compressor via which fuel gas can be directed in a switchable manner past the compressor to the at least one control valve. An energy-saving operation can be achieved in a simple manner by continuously measuring the fuel gas pressure at the outlet of the at least one control valve. A minimum fuel gas pressure, which is desired (e.g., necessary) for operation of the gas turbine, at the inlet of the at least one control valve is determined from the measured pressure values in each case.

  • Patent number: 8579627
    Abstract: A method is provided for controlling the feed of a combustible gas by a valve device placed in a feed pipe which has a gas inlet section and a gas outlet section. The device includes a valve seat in the pipe associated with a membrane-operated plug and a device for returning the plug to a position in which the valve seat is shut off. The method includes the steps of creating a pressure difference in a section of the pipe downstream of the plug with respect to the direction of flow, by a constriction in the pipe having a predetermined cross section, the pressure difference being defined by a first pressure upstream of the constriction and a second pressure downstream of the constriction; collecting the signal formed by the second pressure downstream of the constriction and making the second pressure act on the side of the membrane opposite that on which the first pressure acts; and generating a regulatable load on the membrane of the membrane operating system.

  • Patent number: 7802984
    Abstract: A system and method for providing a gas-fired heating system with improved thermal efficiency includes modulating a quantity of combustion air flow to a combustion mixture in response to a measured change in fuel-gas pressure using a DC (e.g., brushless) motor to drive a combustion air blower. A pressure transducer in a manifold transporting fuel-gas into the combustion mixture outputs a signal proportional to the measured pressure to the motor. The motor speed and thus the resultant quantity of combustion air flow are modulated in proportion to the quantity of fuel-gas to the mixture. Accordingly, a constant fuel-gas to combustion air ratio is maintained. The system and method may further provide for adjusting the output signal to accommodate measured intake air temperature, and/or measured atmospheric pressure in order to maintain a constant, good thermal efficiency (preferably ?80%) regardless of air temperature and altitude at the system's installation location.

  • Publication number: 20020009685
    Abstract: The present invention provides a process of cooking foods using a hydro-fuel to produce super heated in-situ steam. The hydro-fuel is propelled at a regulated flow rate into a pre-heating tube situated near a burner that is used in cooking, but also heats the tube. The pre-heating hydro-fuel is mixed with air in a mixing chamber to form a fuel-air mixture that is then transported to a burner tip on the burner. The fuel-air mixture is ignited at said burner tip to cause combustion producing the release of hot gases and in-situ steam that rise to cook food supported above said burner.

  • Patent number: 4249885
    Abstract: An atomizing nozzle particularly suited for your use in compact combustion chambers. Successful combustion of liquid fuels having generally high viscosity and widely varying properties such as distillation temperatures, distillation rates and impurities, including "heavy" and waste oil. Improved combustion is accomplished through the use of viscosity control and improved fuel atomization. Use of a nozzle utilizing "shearing" of the fuel by an atomizing fluid stream which intersects the fuel at approximately right angles. Recombination of liquid fuel particles is prevented by the use of a controlled "exit orifice" in the burner nozzle. The nozzle also features continuous circulation of the fuel in the nozzle body which establishes orientation of impurities contained in the fuel relative to the exit orifice so that they are expelled through the orifice. Combustion of conventional distillate fuel oil such as API No. 1 and 2 is also provided.
