Pulverised coal/biomass co-fire modelling in a full scale

2012-4-13 · for pulverised coal has been undertaken in this work. Typical Chinese fuels, Huating coal and wheat straw, were burned at coal and under coal/wheat straw co-firing (up to ≈12.5% on a thermal basis). In the experiments, wheat straw has been handled by the existing coal mills and feeding system to a set of dedicated burners.
