Abstract

A model for the estimation of the characteristics of the conversion of the gasification products of solid fuel to a synthesis gas via incomplete combustion is proposed. The unidimensional stationary model is based on the assumption of thermodynamic equilibrium in the synthesis gas at combustion temperature, as it does not require data on the kinetics and rate of chemical reactions in the combustion zone. There are explicit analytic expressions that tie the combustion temperature and composition of the synthesis gas being formed with the composition of the initial gasification products and consumption of the gaseous oxidizer. The calculations of the combustion temperature and composition of the synthesis gas for the conversion of the gasification products of four types of solid fuel, namely, wood, peat, coal wastes, and combustible shales, to the synthesis gas are performed.

Keywords:
