| Popis: | 97 The study utilized the superheated vapor to cook municipal solid waste, investigating whether or not the solid residual can be turned into new.age alternative fuel. The superheated vapor in this study was defined as the pressure is 5 bar and the temperature is between 152℃ to 170℃. The study tried to use the superheated vapor to cook the municipal solid waste. There are at least four different types of municipal solid waste such as Styrofoam, plastics, PET, and food waste to be tested. And the process of cooking those four types of municipal solid waste lasted for 30 minutes respectively. Due to the temperature of the superheated vapor was under 170℃, the researcher examined the hydrocarbon of Styrofoam, plastics and PET with visual detection, and the hydrocarbon of these three wastes were found to be the same as before. The study found out that the volume rate of those three types of municipal solid waste decreased to 35% or lower. Comparing to the reports of ReCycled Refues International, the decreased volume rate in this study is much better than theirs at 50% or more. In addition, through the process of cooking (which lasted for 30 minutes), the smelly food waste became odorless, and the moisture of solid residual (food waste) was taken out as well. However, the hydrocarbon of solid residual (food waste) remained the same as before. The solid residual (food waste) were considered as organic, and were further tested through torrefaction. The results found out that the heating value of solid residual (food waste) were detected more than 5500Kcal/Kg, which suggested that the solid residual (food waste) could be used as alternative fuel. Through the process of torrefaction, the solid residual of the agricultural remainders and the weeds can generate alternative biochemistry energy. And the solid residual of food waste were also proved to be used as alternative fuel. In conclusion, the results of the study suggested that the two alternative biochemistry energy and fuel mentioned above can be applied into thermal power plant. But there still needs more experiments on related issues in the future. |
