Abstract:In order to improve the energy utilization efficiency of rapeseed straw and paper sludge, the rapeseed straw mixed with paper sludge was cold-formed. The physical properties of the new type of rape straw press process fuel were tested from sludge content, molding pressure, water content and straw particle size which was measured by compressive strength. The factor test range was determined by single factor analysis, and the test results were analyzed by the response surface method. The results show that the order of influence is that molding pressure>water content>stalk particle size>sludge content. The optimum molding process parameters of the new type of rape straw press process fuel are: sludge content is 25%, molding pressure is 80kN, moisture content is 15% and stalk particle size is <1 mm, so that the compressive strength of the molding fuel can reach 0.206 kN.
