Study progress on thermal oxidized utilization technology ofultra low concentration gas

Based on the mine gas emission reduction requirements and the application status of the thermal oxidized utilization technology with the ultra low concentration gas, the paper introduced the working principle of the thermal oxidization utilization technology with the ultra low concentration gas. The thermal oxidized technology with the ultra low concentration gas was prepared in references of the VOC processing experience to the development course of the industrialized design guided by the mathematical model optimization. A statement was conducted on the principal study orientation and study progress at home and abroad, including the reaction kinetics mechanism of the inert thermal fillings in the gateway, the thermal wave migration law of the combustion reaction, numerical simulation and approval, nitrogen oxide emission and large dimension experiment study and other aspects. A discussion was conducted on the contradictions, such as the simplified reaction mechanism, reaction products, dynamics parameters and other aspects existed in the process of the study on the thermal oxidized utilization technology of the ultra low concentration gas. Meanwhile, an analysis and prediction were conducted on the study tendency on the thermal oxidized utilization technology of the ultra low concentration gas. The technology would have necessary guidance significances to the science study, numerical simulation calculation, design optimization and engineering application as well as others in the technical filed.
