    摘要: A system for supplying fuel to a gas turbine includes piping containing fuel at a pressure greater than approximately 500 psi. A pressure reducing valve connected downstream of the piping reduces the pressure of the fuel to less than approximately 200 psi. A heat exchanger connected downstream of the pressure reducing valve heats the wet saturated fuel or dry saturated fuel to produce a superheated fuel. A control valve connected downstream of the heat exchanger reduces the pressure of the superheated fuel to less than approximately 50 psi. A method for supplying superheated fuel to a gas turbine includes receiving fuel having a pressure greater than approximately 500 psi and reducing the pressure to less than approximately 200 psi. The method further includes separating gaseous fuel from liquid fuel, reducing the pressure of the gaseous fuel to less than approximately 50 psi, and flowing the superheated fuel to the gas turbine.

    摘要: A method for detecting and controlling the elemental sulfur deposition on pressure reducing gas fuel control valves in cases where the sulfur deposition results from a temperature drop during expansion across the control valve, such as that encountered in gas turbine engines. The control method and algorithm according to the invention uses measured parameters of gas flow rate, pressure and temperature, combined with known pressure reducing valve characteristics to first determine whether sulfur deposition has occurred, and thereafter to calculate a valve position control parameter used to control the gas temperature upstream of the control valve, thereby maintaining the sulfur in a vapor phase through the pressure reducing process and preventing subsequent sulfur deposition on the valve and downstream piping.

    摘要: An external combustion system for a stationary gas turbine engine includes a rich zone combustor, a water or steam quench stage, a lean zone combustor and a dilution stage. Fuel such as natural gas or liquid hydrocarbon, which forms no ash or slag, burns in a primary air supply in the rich zone combustor at an equivalence ratio exceeding 1 which inhibits rapid formation of of oxides of nitrogen. The effluent from the rich zone combustor is a stream of combustible gas including carbon monoxide and hydrogen. The combustible gas stream is quenched in the quench stage and mixed with a secondary supply of compressed air in the lean zone combustor. The combustible gas ignites spontaneously in the lean zone combustor and burns at an equivalence ratio of less than 1 and at a temperature below the range characterized by rapid formation of oxides of nitrogen. The discharge from the lean zone combustor is a stream of hot gas motive fluid which is diluted in the dilution stage and introduced into the turbine section of the engine.

    摘要: The quantity of NOx emissions generated by a combined gas turbine-steam boiler power plant is controlled by recycling a controlled amount of the steam boiler exhaust gas to the air compressor of the gas turbine such that the recycled gases constitutes up to about 30% of the fluid flowing through the air compressor and by cooling the recycled steam boiler exhaust gases to about the desired gas turbine compressor inlet temperature prior to its introduction into the air compressor.

    摘要: An improved dual stage-dual mode combustor capable of reduced emissions of nitrogen oxide from a combustion turbine is disclosed. The combustor includes two combustion chambers separated by a throat region. Fuel is initially introduced and ignited in the first chamber. Thereafter, fuel is introduced near the downstream end of the first chamber for ignition and burning in the second chamber. Burning in the first chamber is extinguished by shifting the fuel flow to burning in the second chamber and after termination of the flame in the first chamber, fuel is reintroduced into the first chamber for premixing only with burning in the second chamber. By selectively controlling the percentage of fuel introduced into the first stage, low emissions of nitrogen oxide are realized.

    摘要: A combustion system for gas turbines is disclosed which is capable of burning gaseous and liquid fuels. Excess air injected into the reaction zone of the combustor produces either a fuel-lean or fuel-rich mixture which lowers the temperature at which combustion occurs and thereby reduces the amount of nitrogen oxides in the turbine exhaust. Efficient combustion is maintained across a wide range of turbine loads by means of a control mechanism disposed externally of the combustor, which directs the airflow from the compressor to the reaction zone and to the downstream dilution zone respectively in a manner which permits variable, inverse proportioning of the air supplied to these zones. The variation in the pressure drop across the combustor is maintained within acceptable limits throughout the full load range.
