The Wood Stove year 2020 - a part of the living environment

This project is a collaboration between Nibe AB / Contura and SP Technical Research Institute of Sweden. Based on earlier evaluations of six different technology tracks, three tracks were selected to further evaluate: CFD modeling, active control and catalyst technology, with the long term goals of particle emission, control of maximum output and long burning time. A literature review of available sensors for O2, CO and hydrocarbons have been conducted followed by a market research, focusing on developments during the last decade and experiences from biomass combustion. Sensors were long-term tested. The lambda probe works well and is affordable, while sensors for unburnt gases still need to be further optimized for accuracy and long-term stability and also become less expensive to be of practical use. Active control has been applied to a prototype and evaluated with good results. In further work with active control, emphasis should be on safety. A CFD method for stove combustion has led to an industrial application with significant cuts in time and resources. Advanced CFD simulation has been used to examine the impact of furnace temperature on wood conversion and how wood log size can be used to counteract an accelerating power output. Simulation results show that log size has good potential to contribute to an improved combustion, but should be combined with further design of the stove. A rig for evaluation of catalyst coatings has been built and experimental results are promising. CO was in principle eliminated from the flue gas and hydrocarbon concentration were reduced down to a level equivalent to 25-70% of the original content.
