This paper reports on burning mill sludge in a fluidized-bed incinerator and waste-heat-recovery system. In the late 1970s, the Lielahti sulfite mill of G.A. Serlachius Corp. (now Metsa Serla Oy) began investigating alternative methods of sludge disposal. The mill had an annual capacity of 100,000 tons of bleached pulp, generated 80,000 tons of by-product lignin sulfonates, and specialized in dissolving pulps. Because of the end product's high quality requirements, the mill had a low pulp yield and high losses in the form of both dissolved and suspended solids.
