“…An initial assessment of the new sample division technique showed this method to be superior to the coning and quartering procedure used in the variability study [3]. This conclusion is confirmed by the results cited in section 4.…”

“…In this work, the within-bag $CV, which corresponds to the combined measurement and sampling error for gram-size samples, is substantially less for all properties than in the prior variability study [3]. The small value for the HHV2 within-bag $CV and its close agreement with the within-bag values for HHV3-B and HHV3-F indicates that the new sample division procedure has reduced our sampling error for gram-size samples to less than 0.8/6.…”

“…Both the sampling and processing problems were examined in context of the variability of MSW for two weeks, a time period appropriate to a specification test of an incinerator-boiler system. Thirteen to twenty-three kilograms of RDF-2 were obtained on each of ten consecutive working days ( Four of the ten day's material were selected for our study: days 6 [3] of the variability of MSW for a two week period in January 1980 consisted of blending (in drums filled with steel balls), coning and quartering, and taking gram-size grab samples. This method was found to be unsatisfactory.…”

“…After an initial study of the variability of MSW was carried out at NBS in 1980 [ 3 ], it was concluded that a calorimeter which could burn a kilogram-size sample with a total uncertainty of less than one percent in the enthalpy of combustion would satisfy our requirements.…”

“…In the last few years, a number of credible surveys [26][27][28][29][30][31][32][33] have shown that recycling and waste-to-energy appear to work well together. Compatibility even exists for several more reasons related to economic, environmental, political, and social aspects.…”

In the last few years, Taiwan has set a bold agenda in solid waste recycling and incineration programs. Not only were the recycling activities and incineration projects promoted by government agencies, but the related laws and regulations were continuously promulgated by the Legislative Yen. The solid waste presorting process that is to be considered prior to the existing incineration facilities has received wide attention. This paper illustrates a thorough evaluation for the first refuse-derived fuel pilot process from both quantitative and qualitative aspects. The process is to be installed and integrated with a large-scale municipal incinerator. This pilot process, developed by an engineering firm in Tainan County, consists of standard unit operations of shredding, magnetic separation, trommel screening, and air classification. A series of sampling and analyses were initialized in order to characterize its potentials in the solid waste management system. The probabilistic modeling for various types of waste properties derived in this analysis may provide a basic understanding of system reliability. IMPLICATIONSThis analysis presents a thorough performance testing and reliability analysis for the refuse-derived fuel (RDF) process that was built as the first pilot plant in Taiwan. The mass balance analysis indicates that such a presorting process for subsequent waste-to-energy facilities may achieve a 50% production rate based on the waste inflow of 30 tons/hr in several test runs. With the resultant higher heat value (30 tons/hr up to 3716 kcal/kg on average) and lower amount of non-combustibles existing in the final RDF products, the systematic implications to energy recovery, combustion efficiency, pollution control, and ash reuse potential in an integrated waste-to-energy facility are phenomenal. Reliability analysis by the identification of probability distribution to each related factor extends the insight in the feasibility study.
