In thermal dynamics and thermal chemistry opinion, inflammation push the piston can generate more transitory torque than motor. This is way the motor can never replace the inflammation method. Coal and petroleum is the most important strategy supplier around the world. It can show the importance of biomass energy in the future. The development of artificial coal or RDF-5 will be the popular tendency. The topic of this research is produce artificial coal by modified RDF. Base on junk recycle, analysis the 6 type of high thermal low chlorine junk collected from incinerator by physical and chemical method to make combination material of RDF. Add edible oil wastes, resin and carbon powder mix with six different ratios of edible oil wastes to make artificiacoal. This sample will take four different analysis: Formation status、Thermogravimetric、Thermogravimetric、Hardness, compare with the nature coal. The ratios of six different edible oil wastes are:9%、19%、29%、39%、49%、54%. In formation status , add less edible oil waste will get better formation result. In thermogravimetric analysis, the heat emission from six samples are:11,998.39cal/g、11,552.25 cal/g、10,735.48 cal/g、10,237.93 cal/g、9,574.07 cal/g、9,157.73 cal/g. Resin has more heat value than edible oil wastes. Because of higher percentage of resin contain, heat emission will getting less by higher edible oil wastes ratio. In theory estimate and experiment result, the sample of this experiment has higher heat value and efficient than nature coal(8,180cal/g). In thermogravimetric analysis, area of graphic overlay will getting smaller by more edible oil wastes added. Thermogravimetric analysis curve will more close to nature coal.Caculating percentage points under the thermogravimetric curve we can get the value for nature coal is 6,945.93%、sample1 is 2,651.21%、sample3 is 3,255.76%、sample4 is 3,300.94%、sample5 is 3,432.61%、sample 6 is3,771.18% . In hardness test, Mons'' hardness scale can reach 3 by 9% of edible oil wastes added. Mons'' hardness scale can reach 2 by 19% of edible oil wastes added. The hardness will smaller than 1 by 29%、39%、49%、54% edible oil wastes added. The hardness range of nature coal is 1~4. The result of this experiment shows less edible oil wastes added will getting close to natural coal. In cost of energy analysis, dispose of waste by incinerator will cost 947,520,000NTD/Month or 11,370,240,000NTD/Year. If use 50% of recycle to produce artificial coal, it can save 1/3 of money to dispose of waste.It can save 157,920,000 NTD/Month or 1,895,040,000NTD/Year. The airpollution after buring of artifial coal is also lower than incinerator and natural coal. It shows a great economic benefit.
