  • Gas turbine apparatus
    Patent number: 5609655
    Abstract: A fuel and air mixing apparatus for a combustor and gas turbine generator. A primary portion of the fuel is injected into the mixing air at long distances from the combustor prechamber. The primary portion of the fuel is almost completely mixed with the mixing air. A secondary portion of fuel is injected into the mixing air in the boundary layer at a short distance form the combustor prechamber. This minimally mixed second portion provides some rich portions of fuel-air in the prechamber to improve stability and reduce the chances of blowout.
    Type: Grant
    Filed: December 19, 1994
    Date of Patent: March 11, 1997
    Assignee: Northern Research & Engineering Corp.
    Inventors: James B. Kesseli, Eric R. Norster

  • Means and method for preventing unwanted accumulation in heat exchangers
    Patent number: 4892139
    Abstract: A heat exchange element in the form of a tube, lies in a particulate laden gas flow and is charged with an electrostatic charge of the same polarity as an electrostatic charge on particles suspended in the gas flow, in order to prevent accumulation on any part of the heat exchange element which would interfere with the rate at which thermal energy can be transferred through the heat exchange element or restrict flow of gas through the heat exchanger.
