Burner and control system:
1. High speed gas burner and ratio control system
Continuous cylinder heat treatment furnace requires the equal heat supply, equally loading the cylinder, and needs to provide large heating load changes, so we choose ratio burning control system. The sleeve tube on the burner nozzle will form a high speed jet steam when burning, can stir up the inside atmosphere and equally supply the heat. The heating of each burner nozzle is ratio control.
In the ratio control system, the burner nozzle will automatically adjust the heating according to the temperature in the furnace, the power, mixture ratio, spraying speed will be adjusted to a best condition, which will effectively improve the burning capacity and reduce the pollution. Through the cooperation of the several burner nozzles, the heat flow will be uniformly distributed in the furnace, which will improve the heating quality of the cylinder and temperature uniform. We also choose controller of high resolution and suitable power burner nozzle to reach a high linearity of the system. That kind of control system is widely used in metallurgy and machine heat treatment industry.
