This master thesis assessed the development of a 25kWth sawdust burning fluidised bed reactor for the woodworking industry. This study had two major purposes: - Investigate methods to improve the intensity of the combustion process in a bubbling fluidised bed reactor in order to minimise emissions of soot, carbon monoxide and nitrous oxides - Develop a 25kWth unit that is simple to use, implementable in the targeted woodworking industry and economically viable Stable combustion of sawdust was achieved in a 1.9meter high reactor of 10kWth with carbon monoxide emissions of less than 200ppm during steady state operation. Carry-over of solids were between 300g/hr at a fluidisation velocity of 0.9m/s and 15g/hr at a fluidisation velocity of 0.5m/s. Experiences and results from these tests were used to develop a 25kWth unit that will be tested in a commercial scenario before the end of 2014. This study has shown that the utilisation of atmospheric bubbling fluidised bed technology for the combustion of sawdust with a thermal power of 10 - 25 kW is feasible. That means that the technology is ready for the introduction in products for SMEs and domestic markets, where as previously it was assumed that the technique was mostly limited to large industrial applications.
