PROPORTION REGULATION OIL BURNER OF LOW PRESSURE AIR TYPE

摘要

The oil burner has an oil nozzle (14), a second air nozzle (16), a first air nozzle (20) and a burner housing (13). The oil nozzle is positioned in the center of a burner body and the second air nozzle for low temperature air is located around the oil nozzle. The first air nozzle is located between the second air nozzle and the burner housing and forms a passage for high temperature air. The amount of combustion air is controlled by advance or retreat of the first air nozzle which cooperates with an oil flow regulator.
