Bubbling fluidized bed installation capitalizes on sludge

摘要

In recent years, the pulp and paper industry has encountered increasing cost and environmental issues associated with the disposal of hyproduct sludge. Fraser Papers, a recycled fine paper mill located in West Carrollton, Ohio, envisioned an oppor-tunity to capitalize on the utilization of sludge as a waste fuel. Studies were conducted and culminated in the selection of a new Bubbing Fluidized Bed boiler (BFB) as the optimum choice in technology to burn high moisture, low grade (Btu) fuel, e.g., primary and secondary waste sludge. The principal mode of operation is to burn 100
