Abstract:
Primary measures for logwood fired stoves have been evaluated and advanced stove concepts showing significantly reduced CO, OGC and PM emissions have been developed and tested. The primary measures covered advanced stove geometries, air supply concepts, air staging concepts as well as process control automation measures. The work performed has been based on two relevant approaches, namely experimental work as well as utilisation of CFD simulations for stove design, optimisation and evaluation. In a first step secondary air injection through nozzles placed at the backwall of the main combustion chamber was implemented and optimised at an appropriately modified chimney stove. Moreover, an automated control system based on combustion air control in dependence of the furnace temperature has been developed, tested and improved. Finally, a better insulation of the combustion chamber was applied to further enhance the gas phase burnout. The different measures led to a stepwise reduction of the emissions by more than 50% for CO, OGC and PM. With the measures proposed it could be shown that stove optimisation by primary measures is possible and shows a great potential concerning emission reduction. This is of great relevance, as the results can be utilised for the optimisation of wood stoves in general with respect to their specific needs.
