Abstract

Alholmens Kraft's power plant represents the best-practise biomass/fossil fuel co-fired power plant concept with extremely diverse fuel range - suitable to be replicated almost anywhere in Europe. By solving operational problems and reducing fuel originated risks in combustion the economics of biomass co-fired power plants can be further improved. Valuable information has been obtained about fuel storing and crushing systems, dust concentrations at fuel receiving station and the applicability of automatic fuel sampling for fuel quality monitoring. With the aid of the data acquired from the pilot- and full-scale combustion experiments, interesting causalities between chemical composition of fuels and the risk for formation of chlorine-bearing deposit formation, including the implications from the use of sorbents, have been found. Special attention has been paid on emission levels (NOx formation and SO 2 autoreduction) in co-firing and on corrosion propensity of fuels.
