- Abstract
- The increased use of the organic portions of municipal solid waste as a fuel can have major impacts on current national isues dealing with energy conservation, materials recycling, and pollution abatement. In principle municipal solid waste is burnable by any of the numerious techniques developed for coal combustion. However, there are important differences in the full range of physical and chemical properties that are important in the design and operation of practical combustion facilities. Direct substitution is in general impracticable and there is now an ample literature on the burning of MSW in inappropriate facilities. The present report is the result of a joint Department of Energy and National Bureau of Standards program with the aim of developing an information base with respect to the combustion related properties of Municipal Solid Waste. It should be emphasized that the purpose of the laboratory studies presented here is not to supply final engineering design data but to furnish preliminary input to the technologists in the sense of providing relative rankings through comparisons of appropriate coal and MSW properties. At the same time it will provide support for a future program of sub-scale (demonstration or pilot) experiments to expand on the concepts and quantify them for scale-up to industrial sizes. A complete plan for this second phase study will be presented and is included as an appendix to this report. With respect to the actual experimental investigations; these consist of three main tasks. Specifically, [A] static measurements (calorimetry, proximates and ultimate analysis; [B] dynamic measurements using the full range of modern thermoanalytical instrumentation and [C] combustion of particulates in a specially constructed laboratory furnace as well as studies on the entrainment properties of MSW. The first two tasks deal mainly with the chemical properties of municipal solid waste and is of general utility. The latter is more specifically orientated. The scale of laboratory instrumentation set definite to the limits particle size with respect to the intrainment and combustion studies. Thus the most straightforward application is to combustion in stokers, including semi-suspension units.
