Study of Thermochemical Conversion of Organic Substances in a Combined Gas Generator
Abstract
Abstract. The article considers a model of equilibrium chemical processes in a combined gas generator. Depending on the composition and humidity of the initial wood raw material, the parameters and composition of the gas mixture formed during the operation of the combined gas generator of the proposed scheme are calculated.
Comparison of the calculation results with the data of experimental studies showed that the proposed model adequately reproduces the course of the gasification and pyrolysis processes.
The proposed model of gasification of wood raw materials using oxygen blast allows you to expand the list of possible chemical reactions, opens up the prospect of research in a single methodological approach to the processes of combustion, pyrolysis and gasification. Within the framework of this model, various oxidants can be taken into account: air, oxygen, steam-air, steam-oxygen and evaporation, as well as various methods of supplying additional external energy: through enclosing structures (heat exchangers) or together with a steam blast.
Further development and detailing of the model will lead to an increase in the number of nonlinear algebraic equations describing chemical processes in a combined gas generator, respectively, to a complication of the procedure for their solution, but will provide a more complete and accurate description of real processes in combined gas generators.
