THEORETICAL AND EXPERIMENTAL STUDIES OF METHODS OF THERMOCHEMICAL PROCESSING OF MUNICIPAL SOLID WASTES
Thermodynamic analysis of thermochemical processing of MSW of Ukrainian origin is performed. The software TERRA was used for calculations, with the help of which the equilibrium indicators of the reaction products were calculated. It is shown that the accuracy of the calculation results is determined by the accuracy of the used value of the lower calorific value. Control calculations were performed for the following substances: pure carbon, glucose, cellulose, polyethylene. Thermodynamic analysis of the possibilities of thermochemical utilization was performed on the basis of studies of the composition of MSW obtained directly from landfills in Ukraine. It is shown that the adiabatic temperature significantly depends on the content of oxides — ash components — and their chemical composition. For experimental researches the laboratory installation was developed and constructed. Measurement of temperature, weight and composition of gas during researches was carried out by means of system on the basis of personal computer using the module of connection of territorial-distribution sensors I-7018 and I-7520 — isolated module of a converter of communication channel SR-232/RS-485. For the first time, a combination of thermogravity analysis with a possibility of chromatographic control of a composition of the gas phase at all stages of heat treatment was proposed for studies of MSW heat treatment. For the first time, kinetic studies of wood gasification were performed using gravimetric analysis with simultaneous determination of the gas phase composition. Bibl. 14, Fig. 4, Tab. 2.
