Abstract: Reverse jet combustion technology is a high-efficiency and low-pollution combustion technology,which can be applied to both gas and pulverized coal combustion.The flow characteristics are determined by the structure of reverse jet and jet velocity ratio.In this paper,the development history,research progress and development trend of reverse jet combustion technology in gas and coal-fired fields were reviewed in detail.The analysis shows that in the field of gas combustion,the reverse jet is mainly used to stabilize the flame,which is characterized by good fuel/air mixing conditions,forming a nearly uniform heat flow field and avoiding local hot spots in the combustion process.However,it is only an exploratory technology for gas turbine and aircraft engine at present.For engineering application,it is necessary to overcome some important problems,such as the reasonable control of the flow field of fuel and air in a narrow space,as well as from the simplification of the device to the enlargement of the project.In the field of coal combustion,for the pulverized coal burner,the reverse jet can form a recirculation zone with controllable components,size,shape and position.It also can directly send the pulverized coal into recirculation zone and control the residence time of pulverized coal in the recirculation zone. Compared with the traditional flame stabilization method,the technology has stronger flame stability,longer residence time and lower pollution,which is more suitable for the high efficiency of low rank coal combustion.At present,the reverse jet combustion technology coupled with other stable combustion and low nitrogen technology provides a new direction for the development of high-efficiency and clean utilization of pulverized coal,and has been applied in practical engineering.But the mechanism research is not in-depth,which limits the further development and promotion of the technology.For utility boilers,part of the primary air or burn-out air is deflected into the furnace in reverse direction,which can alleviate the velocity and temperature deviation of flue gas at the furnace exit under the mode of tangential firing.At present,the main reason is the industrial application of burnt out air tangency,but how to reasonably control the angle,momentum and number of tangency layers of burnt out air remains to be further studied.
