Energy saving burner with combustion air and fuel gas to be fully mixed

The utility model discloses an energy saving burner with combustion air and fuel gas to be fully mixed. The energy saving burner comprises an outer air pipe assembly and an inner air pipe assembly. The outer air pipe assembly comprises an outer air pipe body, a fuel gas inlet pipe, an air cap and a screwed pipe connector, the inner air pipe assembly comprises an inner air pipe body, an inner air pipe connector, a premixing air nozzle and a premixing air pipe, and the inner air pipe assembly is sleeved by the hollow inside of the outer air pipe assembly. A combustion air exhaust of the inner air pipe body is in threaded connection with the premixing air nozzle and the premixing air pipe through the inner air pipe connector, the periphery of the premixing air nozzle is sleeved by the premixing air pipe, combustion air enters the inner pipe body and is exhausted sequentially through the premixing air nozzle and the premixing air pipe to form stirring wind to be mixed with fuel gas in the outer air pipe body. Due to the fact that the combustion air is primarily and fully mixed with the fuel gas, the fuel gas can be completely combusted through a little burner cold air combustion air. Thus, the energy saving burner has the advantages of being low in energy consumption, low in waste gas emission, small in using amount of combustion fans and smoke exhaust fans, capable of saving energy and capable of achieving environmental friendliness.
