摘要： A method of operating a multi-fuel combustion system is provided. The method includes a first phase and a second phase, wherein the first phase includes providing ignition to a combustor basket to ignite a first type of fuel, where the first type of fuel is supplied to the combustor basket through a first conduit. Also in first phase steam is also supplied to the first conduit in addition to the first type of fuel and steam is supplied to the second conduit after the ignition. In the second phase a second type of fuel is supplied to the combustor basket through the second conduit after ignition of the first fuel through the first conduit, while stopping the supply of the first fuel, and continuing to supply steam through both the first and second conduits.

摘要： The invention is based on a gas turbine burner comprising a combustion zone for burning a mixture consisting of combustion exhaust gas to which fuel gas is added, and comprising a fuel intermixing arrangement having a fuel nozzle for spraying the fuel gas into the combustion exhaust gas. In order to achieve low-pollutant and uniform combustion, it is proposed that the fuel intermixing arrangement be designed for spraying the fuel gas into the combustion exhaust gas at at least 0.2 times the speed of sound.

摘要： A gas turbo set including a first turbine, a second turbine, and a combustion chamber connected between the first and second turbines and operated by auto-ignition is provided. The turbines and the combustion chamber are located on a common shaft that may be rotated about an axis. To increase the efficiency of the gas turbo set, the outer periphery of the second turbine is at a greater distance from the axis than that of the first turbine, leading to a reduction in the size and/or the number of turbine blades.
