Recently, in Korea and outside, interest in new renewable energy is growing and facility investment have been made. Waste solid fuel facilities even receive a lot of interest and that project is going along. However, equipment that has been introduced in the country, has occurred such as a problem can not be a clear picture of the characteristics and properties of domestic waste, excess energy is turned on production yield of RDF. In particular, there is a situation in which energy costs are charged to the drying step is increased in predicting unclear water content of the waste loading.
Therefore, in this study because it derives a range of representative moisture content through the Monte Carlo simulation for uncertainty of the moisture content of life waste of domestic, is planning the drying process in the future presents as a reference for evaluating the need for drying process when comparison of production yield and input energy MT facilities currently in operation, analyze, trying suggested alternatives assessment and the need for drying step.
As a result of analyzing statistical data and literature search related to domestic waste, paper, plastic, etc. is analyzed high, based on such variation, the coefficient of variation of the water content of the composition Another household waste in domestic results were analyzed by Monte Carlo simulation of the water content was analyzed as 19.4 to 46.2% with 95% confidence interval criteria.
The moisture content of the waste so you can from about 20 to up to 45% change, which was able to know that there is a need to develop a risk minimization against variations in moisture content.
If that take 1.68% about dry method of lines, so sorting by specific gravity is the main method of selecting domestic MT Facility, comparison result RDF production volume specific energy usage of the facility in accordance with the position of the drying process, line drying after sorting it is thought that the homogenization of water of waste is carried out from the drying method after method, are screened, and increased 27.93% about RDF production combustible content is fuels in organic screening efficiency is increased.
However, because of the situation moisture content of the waste is carried actually,'s being carried up to about 45-55% higher than the results of this study, the equipment planned a range of water content wider planning Property it is necessary to select.
Further, it is determined so aggravate the economy of facilities fossil more energy is used to be homogenized by drying current methods, Being evaluated MBT technology advanced in the country high technical applicability to high moisture content waste and use less energy to operate a facility. Bio-drying the new homogenization method was found to necessity. we must be carried out research and introduce new homogenization measure.
