  • Patent number: 8370044
    Abstract: A gas turbine comprises a plurality of target exhaust temperature determination modules, the plurality of target exhaust temperature modules comprising a nitrogen oxide (NOx) compliance module configured to determine an exhaust temperature at which an exhaust of the gas turbine complies with a maximum permitted level of NOx; at least one bias module, the at least one bias module configured to apply a bias to an output of at least one of the plurality of target exhaust temperature determination modules; and a controller configured to operate the gas turbine to produce the exhaust temperature determined by the NOx compliance module.
    Type: Grant

  • Patent number: 5138959
    Abstract: Hazardous waste treatment method and apparatus are disclosed in the preferred and illustrated embodiment. A feedstock of solid or liquid hazardous waste material is combusted in a plasma generator in the absence of oxygen and converted into non-hazardous components which are collected in a reactor chamber. The non-hazardous components are further converted into a gaseous outflow which is cooled and separated into selected constituents which are collected in storage vessels.

  • Patent number: 4729891
    Abstract: Hydrogen generating method and apparatus are disclosed in the preferred and illustrated embodiment. A feedstock of methane from heated coal and steam or methane obtained by any other means is delivered into a furnace. The furnace (free of oxygen) heats to about 950.degree. F. in vacuum conditions, and converts the methane into elemental carbon and hydrogen gas. The preferred embodiment utilizes an inductive furnace for heating.

  • Patent number: 4602991
    Abstract: A liquefaction process for coal or lignite is set forth. In the preferred and illustrated embodiment, coal or lignite is ground to a suitable particle size and placed in a reactor vessel. The reactor vessel is located within a pressure vessel. Pressure in the vessel is reduced to about 10.sup.-2 torr.Heat is applied. One procedure is to convert the carbon (in the coal or lignite) at an elevated temperature (600.degree.-900.degree. F.) in the presence of hydrogen (at pressures as high as 2,000 psi) into a hydrocarbon mix; depressurization avoids making various oxides and nitrides, and also can be optionally carried out in the presence of iron or iron ore in particulate form acting as a catalyst.
