Abstract

The invention discloses a gas mixing device for a completely-premixed combustion system. The gas mixing device comprises an outer cavity, a gas inlet cavity, a gas outlet cavity, a fuel gas valve and a fuel gas source connecting pipe. The gas inlet cavity and the gas outlet cavity are jointly accommodated in the outer cavity and are communicated with each other, a first slit is formed in a position between the adjacent ends of the gas inlet cavity and the gas outlet cavity, the ends and the outer peripheral side of the gas inlet cavity are hermetically connected with the outer cavity, the end, which is far away from the gas inlet cavity, of the gas outlet cavity is hermetically connected with the outer cavity, and a second slit is formed in a position between the outer peripheral side surface of the gas outlet cavity and the inner peripheral side surface of the outer cavity, is communicated with the first slit and is communicated with the fuel gas source connecting pipe via the fuel gas valve. The gas mixing device has the multiple advantages that the gas mixing device is simple in structure, convenient to implement and high in mixing efficiency, the proportion of fuel gas to air can be freely adjusted, and the like.

Description

technical field [0001] The invention relates to an air mixing device for a combustion system, in particular to an air mixing device for a fully premixed combustion system. Background technique [0002] Combustion system or burner is a general term for devices that make gas and air spray and mix (or mixed spray) combustion in a certain way. Combustion systems are divided into industrial combustion systems, burners, civil combustion systems, and special combustion systems by type and application field. kind. In order to evenly mix the gas and air in the combustion system, the combustion system is usually equipped with a premixing chamber or a gas mixing device, so as to achieve full premixed combustion. Full premixed combustion means that the gas is fully mixed with enough air before the burner. During the combustion process, air supply is no longer required, and the flame propagation speed of full premixed combustion is fast and the combustion efficiency is high. The gas mi...
