Abstract:

This work focuses on the carbon reduction potential from an oxy combustion system. The oxy fuel combustion of biomass and coal co-firing in a power plant in different ratios is studied using the Aspen plus modelling. The carbon and energy balance of various co-firing ratios is obtained. The influences of energy efficiency are also examined for each configuration. The global warming potential results show that the net CO2 emissions reduces as biomass co-firing ratio increases, however the net energy efficiency decreases. The CO2 from biomass is not included in the calculation as it is sequestered from the atmosphere during forest growth. On the other hand, other environmental impact such as Marine Eco Toxicity, Human Toxicity potential and fresh water toxicity potential increase with higher biomass ratios due to associated agricultural practices.
