As part of the collaborative project funded by the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety, a micro gas turbine-based cogeneration system is being developed in connection with a wood gas plant for the production of decentralized electricity and heat. The first phase of this process involves analyzing the wood gas generator and the micro gas turbine separately and then modifying them in preparation for subsequent connection. The second phase is the actual implementation in a pilot plant, involving the connection of the micro gas turbine-based cogeneration system to an atmospheric fixed-bed cocurrent gasifier. The goals of the pilot phase involve the experimental characterization of the operating behavior, the identification of optimization potential and observation of the entire system from a commercial point of view.
Research Tasks at the Institute of Combustion Technology
The most important tasks in this project at the DLR Institute of Combustion Technology are the numerical plant design and the development of a new combustion system for the combustion of wood gas in micro gas turbines. Plant concepts are being created and evaluated for the connection of micro gas turbines to an atmospheric fixed-bed gasifier. An analysis of the micro gas turbine’s stationary operating behavior is carried out using the simulation program for micro gas turbine plants, developed at the DLR. The thermodynamic and control process variables ascertained during analysis help in the design of necessary plant components and of the combustion chamber. In order to use wood gas in the micro gas turbine, a new combustion system is being developed which will guarantee efficient and reliable combustion and produce only low emissions. The DLR continues to coordinate the project as a whole.
