Sintering Behaviour of Wheat Straw Ash with Addition of Additive under Elevated Temperature

L. Wang, J.E. Hustad, M. Grønli & Ø. Skreiberg
In this work, the use of one non­commercial additive to reduce the wheat straw ash sintering tendency was investigated at elevated temperatures. Sewage sludge was blended with wheat straw in different mass ratios. Laboratory sintering tests were performed on the wheat straw and mixtures in the temperature range from 550°C to 1000°C. The ash from the wheat straw and mixtures with sewage sludge addition were producted under different ashing temperatures and characterized with XRF, XRD...
