At present, China faces the dilemma of continuously reducing fossil fuels and continuously aggravating environmental pollution, so that an economic mode of sustainable development is required to be established, the energy structure is improved, the energy consumption mode is improved, the effective utilization rate of energy is improved, various low-calorific-value fuel gases in industrial production and energy production must be fully utilized, and the efficient clean utilization of conventional energy is realized. The combustible components of the low-heat value gas are thin, the conventional combustion technology is difficult to effectively utilize, and the problem of how to realize the effective combustion of the gas and slow down the environmental problem caused by direct discharge is always a difficult problem in the combustion field.

In practical exploration, the phenomena of backfire and misfire of the combustor occur, and even the safety problems such as explosion and the like are caused. In addition, a series of problems that the temperature gradient near the flame surface is steep, the temperature distribution is uneven, the local temperature is overhigh, the combustion is incomplete, the structure of the combustor is damaged due to overhigh internal pressure, the service life of the combustor is shortened and the like are caused.
