The goal of this project, funded by the German Federal Ministry of Economics and Technology (BMWi), is the development and targeted optimization of a reliable, efficient, and low-pollutant micro gas turbine-based exhaust air decontamination system for decentralized electricity production. The process involves oxidizing loaded exhaust air with volatile hydrocarbons (VOC; Volatile Organic Compounds) while combusting natural gas. These hydrocarbons can be found in the chemical industry but also in technical processes such as in paintshops. The VOC-loaded air is sucked into the MGT, compressed, pre-heated and subsequently cleaned in a combustion chamber system which has been developed specially for this purpose. The hot combustion chamber exhaust gases are fed into a turbine, which drives the compressor as well as an electric generator. The thermal energy contained in the clean turbine exhaust gases can finally be used, e.g. for the supply of process heat.
The design of the combustion chamber system and the MGT plant cycle is being carried out in close cooperation with the Company Dürr. The main tasks of the DLR are the development, characterization and testing of a reliable, fuel-flexible and low-pollutant FLOX®-based combustion chamber system . Using parameter studies, the relevant combustion processes in atmospheric tests are analyzed and optimized. This also forms the basis for future operation in a testing plant.
