New combustion systems for gas turbines (NGT)

Objective

Objectives and Problems to be solved:
The objective of this project is to show that the new combustion systems FLOX(r) and COSTAIR are economically and ecologically more efficient than the premixed combustion systems currently used in gas turbines. The following main improvements are sought:· Elimination of pulsation in gas turbine combustion chambers· Increase in the combustion stability in a wide range of excess air ratio · Suppression of high pollutant emissions in the part load operating mode* Increase in the efficiency of gas turbine systems * Replacement of premix burners by the new combustion technology Description of the work: In order to achieve the objectives, the FLOX(r) and COSTAIR combustion systems will be investigated in depth. Their advantages will be defined, quantified and used to modify existing burners or to design a new generation of burners .The advantages of the new systems will be evaluated at two test rigs at the end of the project. The tools to achieve these results will be experimental investigations at the relevant pressure levels and associated CFD simulation work, fundamental studies and model enhancements as well as process and combustion chamber design by the manufacturers involved. The main steps will be as follows:· Experimental and mathematical investigations under atmospheric pressure- Burner and combustion chamber modifications for the operation under gas turbine conditions- Mathematical modelling of the modified burners- Tests of the modified burners under gas turbine conditions - Tests of reliable operation at gas turbine test rigs Expected results and exploitation plans: Expected major results are:
- safe and reliable operation of gas turbines by improving the stability of the combustion process and the avoidance of flame flash back under all operating conditions
- protection of the environment by achieving ultra low emissions of NOx, CO and UHC under part load and reducing CO2 emissions
- increase in the energy efficiency of gas turbines Exploitation of the research results will be - in-house through the industrial project partners,
* by offering licences to third parties and- by publications in journals as well as by student teaching by the universities involved.(r) Registered Trademark of the firm WS Wärmeprozesstechnik GmbH
