Air vent manufactured in mode of forming branch air passages on side wall of main air passage

Abstract

The invention discloses air vents manufactured in a mode of forming branch air passages on the side wall of a main air passage. The geometric characteristics and quantity of inlets and outlets of the air vents are completely different, but the circulation capability of the inlets and outlets are approximately same. The air vent is characterized in that a plurality of branch air passages are formed on the side wall of the main air passage, thus the air vent taking the plurality of branch air passages as the inlets, taking the main air passage as a transfer passage, and taking openings at the upper end of the main air passage as the outlets are formed, the air vent has the characteristics of high heat flow rate and use safety, can be used for producing a combustor with high heat flow rate, high combustion intensity and centralized flame, and is good for improvement of the combustion reaction temperature and heat transfer intensity.

Description

Technical field: [0001] The invention relates to the improvement of the flame hole structure of a gas burner. Background technique: [0002] The fire hole of the gas burner is also called the vent hole. The premixed burner is widely used at present. Since each fire hole is an inlet corresponding to an outlet, and the inlet and the outlet are directly connected, in order to effectively avoid backfire, this type of The fire hole can usually only be processed very small or very narrow. As a result, the flow resistance of the fire hole is increased, and the heat flow of the fire hole is small. Invention content: [0003] The purpose of the present invention is to provide a vent hole with large heat flow and high safety factor, which is made by opening several branch air passages on the side wall of the main air passage. [0004] Technical solutions: [0005] The present invention is composed of main air passage and branch air passage, and its structural feature is that sever...
