THE EXPERIMENTAL STUDIES OF LITTER POULTRY MANURE UTILIZATION BY THERMAL DECOMPOSITION THROUGH STEAM GASIFICATION
The problem of the low environmental friendliness and economic efficiency of using the known methods of poultry manure disposal is discussed. A technical solution is proposed in the form of modernization of gasification plants by using an alternative gasification agent - steam. The installation and the experimental research methodology are presented, including the operation of the installation, the controlled parameters of gasification of poultry manure and instrumental support; the criteria for modernization in the form of the content of combustible compounds in the synthesis gas and the concentration of nitrogen oxide are selected. The temperature in the gasification chamber and the amount of steam supplied to the gasification chamber were taken as factors. The results of the experiments are presented in the form of tabular data with the equations of reactions proceeding in the gasification chamber. As a result of the analysis of experimental data it was proved that during steam gasification, the quality of synthesis gas increases and reaches values of 11203-11233 kJ kg. The optimal amount of supplied steam is 0.220-0.273 kg kg. The concentration of nitrogen oxide during steam gasification reaches 10-5 molar fractions with manure moisture content of 35%.
