Producer gas engines - Analysis of operating characteristics
The aim of this project has been the characterization of biomass producer gas as a fuel for stationary gas engines in heat and power production.
The aim of the project is the investigation into the utilisation of producer gas as a fuel for stationary gas engines in heat and power production. By investigating and analysing engine-operating characteristics such as emissions, performance, efficiency and other operating variables it is possible to identify and predict problems. In order to determine any cyclic variations of engine-operating characteristics and possible relations to variations of gasifier-operating characteristics, the measured data is processed statistically. By modeling the combustion process it is possible to gain a complex understanding of producer gas as a fuel and - if possible - optimise power and efficiency and reduce emissions. Likewise it will be possible to related measurements made on small experimental engines to large stationery engines in a power plants. The results will forth going be published as papers in international scientifically journals and as presentations at conferences both national and international. The project is a PhD project
More than 3000 hours of gas engine operation, with producer gas as fuel, has been conducted at the biomass gasification combined heat and power (CHP) demonstration and research plant, named 'Viking' at the Technical University of Denmark. The plant and engine have,been operated continuously and unmanned for 6 test periods of approximately 500 hours each. Producer gas properties and contaminations have been investigated. No detectable tar content was observed in the gas that goes to the engine; this was confirmed by three different measuring methods. Likewise, no particles were detected in the gas. Considerable amounts of NH_3 were measured in the produced gas. An analysis of engine operation at varying load has been carried out. Standard emissions, load and efficiency have been measured at varying operating conditions ranging from 90% to 50% load. Biomass producer gas is an excellent lean bum engine fuel, operation of a natural aspirated engine have be archived for 1.24
