Abstract:
Several technology options are available that can help improve the sustainability of biomass integration in small scale Combined Heat and Power (CHP) plants under Norwegian conditions. Demolition wood available from the Norwegian construction industries can be used to produce process heat and electricity as well as co-products such as char. This biomass fuel can reduce process energy costs, provide a consistent source of renewable electricity for the local utility, and increase the renewable energy balance for the country. An Aspen Plus model is used as a basis for the integration of biomass-fueled CHP systems. Several combinations of combustion and gasification systems, power production cycles, biomass fuel combinations, and air emission control technologies are evaluated. The aim is evaluate the cost-efficiency of introducing small-scale biomass CHP technologies of less than 10 MWth input in the Norwegian bioenergy system. In this paper, standard biomass grate combustion based CHP (base line configuration) is compared with gasification and pyrolysis integrated alternative CHP schemes for reduced greenhouse gas emissions and improved electrical efficiency as well as char co-product.
