Improved single-segment type tubular burner

Abstract

The invention discloses an improved single-segment type tubular burner which comprises a burner tube body, a mixer and a gas equalization tube. The gas equalization tube is arranged inside the burner tube body, and an interval space is formed between the side wall of the gas equalization tube and the side wall of the burner tube body; one end of the gas equalization tube is provided with an opening, the other end of the gas equalization tube is closed, and the side wall of the gas equalization tube is provided with a plurality of air outlets. The caliber of each air outlet of the gas equalization tube is smaller than that of the opening, resistance of air exhaust is large, part of dynamic pressure energy of the gas entering the gas equalization tube is converted into static pressure energy due to influences of resistance of the air outlets, so the tube is filled with mixed gas, the function of primary gas equalization is achieved, and it is guaranteed that the gas amount of each air outlet is nearly equal. After the gas ejecting from the air outlets enters the interval space, as the gas suddenly enters a large space, the flow rate is reduced, so the dynamic pressure energy of the gas is immediately converted into the static pressure energy, the function of secondary gas equalization is achieved, and accordingly it is guaranteed that the fire power in the near end, the middle end and the far end of the tubular burner is balanced.

Description

technical field [0001] The present invention relates to an improved single-stage tubular burner. Background technique [0002] The "tubular burner" in the oven of baking equipment is the core. It is an important part that provides a continuous source of heat for the oven and ensures uniform temperature in the furnace. The tubular burner is generally a single-stage integral structure, including a mixer with an air inlet and a gas inlet, a burner tube body, and a regulating valve core installed in conjunction with the mixer, and the amount of gas entering is controlled through the valve core adjustment. [0003] For the single-stage integral tubular burner, due to the long body of the burner and the large internal space, it is difficult for the mixed gas to fill the body in a short time after the mixed gas enters the body from one end. The firepower of the near end, the middle end, and the far end is unbalanced. These phenomena can easily cause the temperature of the left, m...

Problems solved by technology

[0003] For the single-stage integral tubular burner, due to the long body of the burner and the large internal space, it is difficult for the mixed gas to fill the body in a short time after the mixed gas enters the body from one end. Unbalanced firepower at the near end, middle end, and far end

These phenomena can easily cause the temperature of the left, middle and right sides of the oven to be uneven, and the baked food cannot be baked with different firepower at different times, resulting in uneven heating of the food.

[0004] The multi-stage tubular burner used is expensive because of the addition of more accessories and related components. For more than a few manufacturers, customers cannot afford this part of the increased cost.
