| Summary: | 碩士 === 元智大學 === 機械工程學系 === 94 === Due to the raise of living quality, paper consumption are also increased in recent years. The portion of recycled paper is highly increased to meet the goal of environmental protection. The amount of used paper is about 200 tons last year. Paper mills use landfill, incineration or co-fired to handle the used paper problem. Landfill will cause a lot impact to the environment. Incineration will produce dioxin and need to invest a lot of money for the pollution control equipments.
To resolve this problem, some research use circulating fluidized bed gasified boiler to burn the paper reject and obtain the combustible gases .to provide PC boilers as the gas fuel. Although the gasified process can eliminate some major problems of the incineration or co-fired, people still can not handle the forming product (such as glass, sand) of the hydro-cyclone machine. In addition, the ashes still need to be processed by landfill. To improve this process, we intend to use high temperature (1500 to 2000 ) plasma gasified process to handle the slagging product. With suitable adjustment of the additives, they can be used as F-class or C-class cement.
The research goals are :
(1) Adjustment of sludge, paper reject and sand, glasses from hydro-cyclone to proceed the gasification process. Use XRF to analyze the concentration of slagging, and compare with the F-class and C-class cement and conclude the optimized propotions of fuel.
(2) Adjustment of various propotions of fuel to proceed the gasification process. Use GC to study the concentration of the syn gas. Also, the calorific value and char content of the syn gas will be analyzed to calculate the conversion factor.
