Experimental Studey on Fuel Production with the Use of Sewage Sludge

The present study is to produce the high calorific fuel using sewage sludge. Consideration is given to the effects of implication water rate of sewage sludge, temperature, and vacuum pressure on the optimum production condition and the high calorific fuel. In order to reduce the initial moisture content of sewage sludge, the vacuum drying method which is modified here is employed. It is found from the study that the lower implication water rate causes the higher caloric fuel and the maximum calorific value developed here is similar to that of woody pellet for reference. This application will accelerate the reuse and reduce of sewage sludge.
