Patent ID: 7363756

Claim:
A method for combustion of a fuel, in particular in a combustion chamber of a gas turboset, comprising: introducing a combustible fluid into a combustion space through at least one entry nozzle to form a combustible fluid open jet, the combustible fluid selected from the group consisting of a fuel and a combustible mixture; admixing recirculated flue gas from the combustion space to the combustible fluid open jet in order to dilute the open jet and increase temperature of the open jet; wherein the increase in temperature is such that the combustible fluid which has been diluted is brought to a temperature which leads to spontaneous ignition thereof; and wherein flow of the combustible fluid open jet has a flow velocity greater than a flame front velocity of the combustible fluid, such that formation of a stable flame front is avoided and the combustible fluid open jet will entrain flue gas surrounding the combustible fluid open jet in accordance with the jet pump principle, whereby at least part of the flue gas is admixed into the combustible fluid open jet through jet-induced recirculation internally within the combustion space.
