Abstract

The object of research is the combined 2-component solid fuel «coal-municipal solid waste» (MSW) in 5 parts with concentrations of 0–100 (wt. %) of each component. One of the most problematic places is the improvement of solid waste gasification processes, including the optimization of synthesis gas characteristics.

In the course of the study, laboratory thermogravity equipment is used, which is a physical model of a flow-type reactor with recirculation of intermediate reaction products. This installation includes a TGA (thermogravimetric analysis) installation unit, a chromatograph, a computer with a printer, and an automatic data-tracing system using computer methods, namely, thermogravimetric and chromatographic analysis.

The study shows that the method of complex (TGA+gas) laboratory analysis can evaluate the calorific value of non-traditional, including combined, fuels. The determination of the dependence of the calorific value of gasification products of combined fuels on their composition and process parameters is in the range of 6–12 MJ/m3. This is due to the fact that the method and installation proposed in the work has a number of features, the ability to support the calorific value of non-traditional, including combined fuels at a given level. Achievement of the effect is expected due to the choice of concentrations of components corresponding to a given value of Qнр. Thanks to this, it is possible to obtain constant values of Qнр upon receipt of various lots of solid waste for the production of synthesis gas without correction of technological parameters.

The technique presented in the work allows for an express assessment of various batches of solid waste and determine the optimal ratio of coal-solid waste. Compared with similar well-known methods, this provides the following advantages: stability of technological parameters, intensification of production and cheaper synthesis gas.
