  • Patent number: 6784565
    Abstract: In an integrated turbogenerator system having an air intake for a compressor to supply combustion air to a combustor, an electric brake device such as a resistor is connected to the electrical power output of the turbogenerator and is situated in the air intake to be cooled by the stream of combustion air flowing into the intake. When load transients require unloading excess electrical power produced by the turbogenerator, the brake resistor is supplied with at least part of the excess electrical power to create heat energy and thereby heat the in-flowing combustion air to lower the combustor efficiency, turbogenerator power produced, and excess electric power to be unloaded. An algorithm may be provided for controlling the turbogenerator speed deceleration rate to maintain the brake resistor at or near a physical temperature limit.

  • Publication number: 20040160061
    Abstract: The present invention provides a gas-turbine engine and a combustion system that include a catalytic reactor and a turbine. The catalytic reactor oxidizes low BTU fuel to generate thermal energy. The turbine converts the thermal energy produced by the catalytic reactor into mechanical energy. This mechanical energy can be used, for example, to produce electricity. The gas-turbine engine and the catalytic combustion system are capable of oxidizing fuels having a higher heating value in a range of between 1000 and 5 BTU/scf.

  • Publication number: 20040148942
    Abstract: The present invention provides a method for sustained catalytic combustion of low BTU fuels in a gas-turbine engine, and applications thereof. The method comprises ingesting fuel and combustion air into a catalytic reactor to produce thermal energy and converting the thermal energy to mechanical energy with a turbine. The fuel and the combustion air are mixed to form a fuel-air mixture. The ingested combustion air is used to oxidize the ingested fuel. Fuels having a higher heating value in a range of between 1000 and 5 BTU/scf are mixed with the combustion air and oxidized using the catalytic reactor.

  • Publication number: 20040144098
    Abstract: A low emissions combustion method wherein, in an embodiment, a plurality of tangential fuel injectors introduce a fuel/air mixture at the combustor dome end of an annular combustion chamber in two spaced injector planes. Each of the spaced injector planes includes multiple tangential fuel injectors delivering premixed fuel and air into the annular combustor. A generally skirt-shaped flow control baffle extends from the tapered inner liner into the annular combustion chamber downstream of the fuel injector planes. A plurality of air dilution holes in the tapered inner liner underneath the flow control baffle introduce dilution air into the annular combustion chamber while another plurality of air dilution holes in the cylindrical outer liner introduces more dilution air downstream from the flow control baffle.

  • Publication number: 20020148229
    Abstract: A system and method for modular control of a multi-fuel turbogenerator include separate controllers for controlling fuel supplied to the combustor and power output from the generator. The power controller generates a fuel command based on the required turbine exhaust temperature, where the fuel command is independent of the particular fuel being used. Fuels may include natural gas, diesel, propane, waste gas, or gasoline, for example. The power controller communicates the fuel command and the airflow or calculated air/fuel ratio to the fuel controller which selects an appropriate mode of operation for the injectors. Injector operating modes include one or more pilot modes where fuel is not mixed with air prior to combustion, and one or more premix modes where fuel is highly mixed with air prior to combustion.

  • Publication number: 20020104316
    Abstract: A system and method resulting in a balanced minimization of detrimental hydrocarbon, CO and NOx emissions by regulating the air to fuel ratio in a combustor. The turbogenerator system includes a recuperator which separates air flow into a primary passage and a dilution passage. A combustor is connected to the recuperator. The cumbustor has a primary zone and a dilution zone. A controlled air valve is disposed in the air flow such that air to fuel ratio in the primary zone of the combustor is regulated at a predetermined level which minimizes the emissions.
