Detailed operational mapping of a grate fired Biomass combustion plant for improved combustion process control

Biomass combustion plants in Norway are facing stricter emission regulations and lower profitability, mostly due to low energy prices. Hence, performance optimization through improved combustion process control and/or retrofitting becomes very attractive to existing plants. However, the trial and...

Dampening of wood batch combustion heat release using a phase change material heat storage: Material selection and heat storage property optimization

The use of wood stoves for space heating in energy effective residential buildings can be problematic due to the batch combustion giving a highly transient heat production and the limited regulation of the combustion process. Increasing the heat storage capacity and lowering the maximum heat release...
