Combustion Behaviour of Straw Pellets and its Potential Optimisation by Fuel Improvement

N. Weller, T. Zeng & V. Lenz
Besides the development and optimization of boiler systems the fuel and combustion properties of straw pellets should be improved for an increased utilization in small heating systems. Common problems related to the combustion of straw are high emissions of gaseous HCl and SO2, high particle emissions and ash slagging. Therefore in the presented work the combustion behavior of different straw pellets is investigated focusing on emission formation. Six different types of pellets, modified by different...
