Generally, the structure of a mixing pipe for mixing air and gas in a gas burner is divided into a spray burner and a vertical burner. The spray burner is a part of the air required for combustion when the gas ejected from the nozzle is introduced into the mixing tube Primary air) is sucked into the mixing pipe, gas and air are mixed, and the mixed gas is burned in the ditch, and new air (secondary air) is sucked again around the flame to completely burn the mixture. It is known that the thermal efficiency is higher than the Bunsen formula. The existing prior art mainly adopts a method of shortening the cooking time by simply increasing the gas consumption amount by arranging the head dike in two rows in the Bunsen style. Recently, By arranging in two rows, maximizing thermal efficiency, gas consumption is reduced, but height of mixing tube is about 10mm higher Due to the nature of a problem that can not be installed on the set of spatial products are limited circumstances in product development.
