Beschreibung
Zusammenfassung:	The utility model relates to a fuel gas-air ratio automatic-adjusting burner, which is used for all kinds of heating furnaces with natural ventilation which make the gas as the fuel in the petroleum industry and chemical industry, and the needed air quantity for combustion of the fuel gas-air ratio automatic-adjusting burner can be automatically adjusted as the ratio. The fuel gas-air ratio automatic-adjusting burner is provided with a pneumatic balance device and a pneumatic actuating mechanism. As the change of the pressure of the fuel gas, an air regulating board which is synchronously driven and is arranged in a special-shaped air intake chamber can move backwards and forwards, and the air intake quantity can be adjusted as the ratio. Meanwhile, the spray head of the fuel gas-air ratio automatic-adjusting burner adopts a multiple jet which is arranged in cross-shaped and a plurality of spiral-flow sheets with the angle from 30 DEG to 45 DEG to improve the mixed effect of the first fuel gas and the secondary fuel gas, and the heat efficiency is improved by 10%.
