ABSTRACT
Solid fuels conversion in vortex apparatuses allows the processes of heat and mass transfer intensify significantly through the high-turbulized rotating flow creation. It will lead to the possibility of compact plants designing that are perspective for power engineering. According to the results of this work, the vortex multistage gasifier scheme are developed. It should be noted, that the difficulty of the vortex process control requires the multistage conversion and the operating modes organizations to optimal process parameters maintain in the different gasifier zones. A series of coal conversion tests in air were performed in a thermogravimetric analysis system, at non-isothermal heating conditions for modeling the conversion process in the gasifier. The experimental thermal imaging technique of low-calorie fuel gas combustion study are developed. It is used to determine the efficiency of this process and to improve the quality by microjets introducing into gas flow.
