  • Patent number: 9091446
    Abstract: A combustion device used in gas turbine engines that produces propulsion or rotates a shaft for power generation includes an annular combustor with a system of fuel and air inlet passages and nozzles that results in a flameless combustor, such that there is not an anchored flame as in typical gas turbine combustors. The fuel and air inlets are placed at various longitudinal locations and circumferentially spaced, and take on several different configurations where some nozzles inject only air and others inject a rich fuel-air mixture. The combustion device provides an optimal mixing of fuel and air as well as creates an environment for combustion that reduces pollutant emissions reducing the need for costly pollution control devices, and enhances ignition and flame stability, reduces piloting issues and improves vibration reduction.

    Abstract: A thermal conductive heating and desorption system is disclosed, which provides superior results to other systems for the removal of pollutants from soil, groundwater and other affected medias using a novel enhanced gas fired recuperative heater and oxidation system. Pollutants in the affected, heated media are partially destroyed by hydrolysis, pyrolysis and/or oxidation processes. Remaining pollutants are extracted from the affected media, and pollutant off gas is then introduced into the heater system where it is both thermally and catalytically oxidized. Heat from combusted fuel and pollutant off gas in the heater system is used to preheat incoming combustion air through a recuperative heat exchanger, enabling significant reductions in fuel usage by the heater system. Combusted fuel and off gas discharged from the heater system may be further treated to achieve specified discharge standards.

  • Publication number: 20120276490
    Abstract: The burner (1) according to the invention comprises a main body (10) provided with an operating cavity (11) open at least on a first side. The burner also comprises first feed means (20) arranged to introduce a flow of a first reagent (for example combustion air) into said cavity and second feed means (31) are arranged to introduce a flow of a second reagent (for example fuel) into the same operating cavity. The first means are configured so as to introduce the first reagent according to a tangential direction, while the second means are configured to introduce the second reagent according to a direction parallel to the direction in which the cavity extends. According to the invention the operating cavity comprises a first portion between the intake position of the first reagent and the intake position of the second reagent. This first portion defines a stabilization chamber of the flow of the first reagent.
