About project
The purpose of the project is to develop and improve the modelling methods for biomass combustion and co-combustion in circulating
fluidised bed (CFB) boilers. Such method are essential for reliable design and scale up of boilers, but are at present to a large
extent lacking.
The properties of different biomass fuels are quite different from typical coal-type fuels and the properties of biomass fuels vary largely both with respect to moisture content and fuel size and shape of fuel particles, e.g. from fine sawdust to long strips of bark or to large chunks of waste wood. The flow properties affect the mixing of biomass inside the circulating bed and thus the combustion behaviour. Moreover, the chemical composition of biomass (containing e.g. alkali and alkaline earth metals) can be problematic.
The main deliverable from this project is a basis for design of biomass-fired CFB boilers for heat and power generation. The objective is to improve the design tools and modelling methods concerning combustion of biomass in circulating fluidized bed at scales ranging from small scale to utility scale units. With improved tools and models, the new boiler units can be optimally designed and operated, which increases the performance, availability and efficiency and decreases the emissions of the power plants using biomass. The results from the project and the experiences gained of biomass firing will encourage European utility companies for increasing the usage of biomass as primary fuel in new power plants or as a secondary fuel in co-combustion in existing power plants currently using fossil fuels. This will support the EU's renewable energy strategy.
