BURNER FOR A COMBUSTION SYSTEM WITH A PREMIXING ELEMENT AND COOLING ELEMENT, COMBUSTION SYSTEM WITH THE BURNER AND USE OF THE COMBUSTION SYSTEM

摘要

A burner for combustion a combustion mixture is provided. The burner comprises at least one burner body with at least one cooling element for cooling the burner body and at least one premixing element for mixing a fluidic combustion component and at least one additional fluidic combustion component for providing the combustion mixture, wherein the cooling element and the premixing element are integrated in the burner body and the cooling of the burner body can be carried out by the fluidic combustion component and/or by the additional fluidic combustion component. The premixing element is developed for cooling the burner body. Thereby fuel and/or air (combustion reactants) can be used for the cooling of the burner body. In order to ensure a high thermal conductivity between cooling element and the burner body the cooling element is integrated into the burner body. Preferably the mixing element and the cooling element comprise open pores. In addition, a combustion system with at least one such burner is provided as well as use of the combustion system for producing electricity by combusting a combustion mixture. Exhaust gas of the combustion process drives a turbine with which the electricity is produced. The combustion system is preferably included into a gas turbine.
