Abstract:
At present, producing energy along with minimal environmental load is a basic requirement. It includes reduction of greenhouse gas emissions as well. To achieve this in Hungary, the largest potential is related to the utilization of solid biomass (wood, agricultural by-products). A feasible way to include solid biomass in the production of energy is associated with co-combustion. Since 2006, Vértesi Erimo Zrt. (Oroszlány, Hungary) has continuously increased the proportion of biomass in its in pulverized coal hybrid-fluidized boilers, achieving thereby considerable decrease in CO2-emission. Following a description of the architecture of the power plant, this paper demonstrates the impact of biomass co-combustion on steam boiler through an analysis of various fuel mixtures. As the results suggest, an increase in the proportion of biomass entails rearrangement of heat transfer in such a way that a greater difference in temperature of the flue gas is obtained on convective surfaces.
