Blowed premixed efficient gas burner

Abstract

The blown premixed efficient gas burner consists of a burner head, a mixer, a fuel gas nozzle, a combustion flow regulator, an air inlet pipe and an air inlet shutter. The burner head has homogeneously distributed fire slots, an air cavity with secondary air holes and a secondary air pipe. The burner head has combustion cooperated with the combustion flow regulator to replenish the air required for secondary combustion. The present invention has high combustion stability, complete combustion, high combustion temperature, high heat efficiency, wide application and other advantages.

Description

technical field [0001] The invention relates to a burner for gas, in particular to a burner for public kitchen stoves, civilian stoves and stoves using coal gas, liquefied petroleum gas and natural gas. Background technique [0002] The basic structure of the current technology blast premixed gas burner is composed of a burner head, a mixer, a gas nozzle, an air inlet pipe, and an air inlet pipe damper. The inner cavity of the burner head is connected to the mixer, and the gas nozzle is installed on the In the middle of the end of the mixer pipe, the air inlet pipe is connected to the mixer, and the air inlet pipe is provided with a damper, and various styles of combustion fire holes are opened on the burner head to form various burner heads with different structures. After the gas is mixed with the blast air in the mixer, it is transported to the burner head chamber and sprayed out from the fire hole for combustion. The air intake volume of the primary air is adjusted by ad...

AI Technical Summary

Problems solved by technology

In order to stabilize the normal combustion of gas in the existing technology, the air index of the primary air intake volume, that is, the mixing ratio of gas and air, must be strictly controlled. When the air index is greater than the combustion range, that is, when the air intake volume is too large, misfire will occur And incomplete combustion conditions, when the air intake is small, insufficient combustion will occur, and affected by the burner head fire hole setting and premixed air, the burner has poor versatility for various gases, and the combustion effect is poor when the gas is replaced. Or can't burn normally

In addition, this kind of burner is only suitable for open combustion environment, and there is no effective secondary air oxygen supply in the sealed combustion environment, so it cannot burn normally and fully; because its stable combustion is the steady flow combustion of the flame itself, the combustion temperature is relatively low , cannot fully burn the gas
