The project focuses on the optimization of a wood gasification plant as well as on its coupling to a micro gas turbine for decentralized heat and power generation. In the project’s first period the subsystems, wood gasification and micro gas turbine, will be considered as virtually connected. Hence, each component will be separately analyzed, purposefully optimized and modified in order to prepare the subsystems for their actual coupling. For future development of the gasification technology, detailed measurements will provide information for the assessment of operating behaviour and product gas composition. Another main topic is the examination of various biogenic substrates from residual biomass/biomass from landscape, comprised in the biomass ordinance. Analyzing biogenetic substrates will give further information about substrates’ influence on product gas composition and requirements for product gas cleaning and conditioning. A fuel-flexible, low emission combustion system will be developed and tested for the combustion of product gases.
Furthermore, various power plant and operating concepts will be examined by the use of numerical models and extensively analyzed in terms of their economic efficiencies. Technological transfer between the project partners and the implementation of the pilot power plant will take place in the second period which is the demonstration phase of the project. The demonstration power plant will be operated to characterize the combined system and to optimize single components. Based on the experiences of the continuous operation, the economic efficiency of the power plant concept will be analyzed and problems during operation will be documented.
Therefore, in a first step, the present subsystems are separately analyzed, specifically optimized and modified for the combined system. Furthermore, plant and operating concepts will be elaborated and an innovative combustion system for micro gas turbines will be developed. In addition, product gas cleaning and conditioning will be optimized and economical efficiency analysis will be carried out. Subsequently, technological transfer will be realized by the implementation and continuous operation of an actually coupled pilot power plant.
