Investigation of slagging in pulverized fuel co-combustion of biomass and coal at a pilot-scale test facility

摘要

One option to reduce the CO_2 emissions is biomass used for energy production. Co-combus- tion of biomass in existing coal-fired power stations offers a great potential. In pulverized coal combustion facilities, one implementation problem is the tendency of slagging and fouling of biomass. At the IVD, experiments were carried out to obtain information about biomass deposit characteristics in pulverized fuel (pf) co-combustion. This paper presents results from the IVD 0.5 MW pf combustion experimental facility obtained from different tests with coal-biomass mixtures Ranging from small biomass shares up to a pure biomass firing.
