Abstract:
Based on the general rising energy demand and the ambitious climate protection targets, the use of biomass for combustion will gain even more importance than it already has. One alternative biomass feedstock is hay which is no longer required as fodder because of decreasing animal livestock. However, high chlorine and sulfur emissions as well as ash slagging tendencies are common problems related to the combustion of hay. Therefore, the combustion behavior of two different hay assortments and its potential optimization via the addition of mineral additives were studied. Combustion experiments were performed with a commercially available boiler (30 kW) measuring the gaseous content of CO, O2, TOC, NOx, SO2 and HCl in the flue gas as well as the particulate matter emissions. These particle samples were also analyzed for inorganic material. Results show great differences in the emissions behavior of the two hay types and a positive influence of both additives. Particle emissions have been reduced about 15 to 30 w.% depending on the fuel composition.
