BIOMASS GASIFIER BURNER FOR A STIRLING-CHP
DURATION 2018 - 2020

With the start of the project in October 2018 the entry into an exciting research project took place, which is co-financed by the European Fund for Regional Development and the State of Upper Austria. It is a compact wood carburetor burner for pellets and wood chips, operated with our fagatec® engines.

Since the Stirling engines can add the hot wood gas directly to the combustion, it can be expected that the process steps gas cooling and tar condensation are unnecessary. Along with this, the system costs and the maintenance costs of the wood gas CHP are reduced.

RESEARCH PROJECT "BIO WASTE STIRLING" DURATION 2017-2020

In partnership with the chair of FAU Erlangen and the municipal utility of Wunsiedel, a fluidised bed combustion was developed for the thermal utilisation of different biogenic residues (e.g. hay and straw pellets, pressed fermentation residues and sewage sludge pellets). For this purpose, an A600 alpha engine was equipped with a heat exchanger designed specifically for fluidised bed applications. The system is still in test operation but it has been demonstrating an extremely satisfactory performance since the beginning.

FFG PROJECT „READY-TO-CONNECT LEAN-GAS CHP“ DURATION 2016-2019

This research project includes the development of an efficient burner for lean gas with particular consideration of emissions along with a power-upgrade of the already developed A600 Stirling module. The still ongoing project has already led to substantial innovations, for example the invention of the fagatec® AlphaGamma® technology with an overall efficiency of 31% (lower heating value fuel to electrical output), which is noteworthy for Stirling engines.

FFG RESEARCH PROJECT "STIRBIO" DURATION 2013-2016

In partnership with a biomass boiler manufacturer, a research institution named Bioenergy 2020+ from Wieselburg, as well as the University of Vienna, a project of a small CHP spread out over 3 years was completed with outstanding success. Using a modified pellet biomass boiler from a commercial series, an A600 Stirling engine was integrated into the hot combustion gas stream on its upper side. With the help of CFD simulation, the combustion process and the heat transfer was improved and practically implemented. A significant focus was placed on determining the impact of ash deposits on various heat exchanger designs with respect to output losses. With a clean heat exchanger, an electrical output of 5 kWel and an overall electrical efficiency (lower heating value fuel to electrical output) of 15% could be achieved, which is astonishing for this class.

FFG PROJECT „DEVELOPMENT OF ECONOMICAL, HIGH EFFICIENT EXCHANGERS“
DURATION 2009-2013

In the course of this project, we learned how to manufacture the cooler, regenerator, and heat exchanger. The investment in a vacuum soldering oven assisted us considerably during development, which ultimately culminated in a reliable production process.

FFG PROJECT „STIRLING ENGINE“ DURATION 2002-2008

In this project, the development of an innovative Stirling engine was funded by the Austrian Research Promotion Agency. In the course of the project, a learning process of an unforeseeable scope was initiated. Nevertheless, the project ended in a first operable engine with the internal designation T350.
