【Abstract】 Seweral kinds of burner systems are expounded and different systems suit different heat power.The relation equation of pressure drop in oil tank vers burning time and the air volume is established.The characteristic equations,the optimum equations of injector and burner house are given and analyzed.There is an optimal geometric parameter which keeps the optimal condition of injector consist with the optimal condition of burner house.The distance between the outlet of nozzle and inlet of mixing pipe is important,and the distance equations are also introduced.All will be helpful to the design of burner systems and the systems regulating.更多还原
