Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] Figure 4 It is a top view of the flame-stabilizing structure of the existing high-efficiency burner, which adopts parallel small holes for flame-stabilizing, and a plurality of small-hole flame-stabilizing holes 3' are arranged on both sides of the main flame hole 2', the flame-stabilizing effect is poor, and the flame-stabilizing flame of the flame-stabilizing holes The distance away from the burner plane increases with the heat intensity of the burner of the main burner hole, and there are problems such as excessively high flame burning the heat exchanger, combustion noise, and excessively high exhaust gas index.

[0034] In order to solve the above problems, the present invention provides a high-efficiency burner flame-stabilizing structure, such as figure 1 , comprising a fire hole plate 1, a plurality of main fire holes 2 are pr...

Abstract

The invention relates to an efficient combustor flame stabilizing structure which comprises a fire hole plate. A plurality of main fire holes are formed in the fire hole plate, the main fire holes are long-strip-shaped holes and are arranged in parallel at intervals, flame stabilizing holes are formed in the two sides of the main fire holes, the flame stabilizing holes are long-strip-shaped holes parallel to the main fire holes, and the opening plane of the fire hole plate is perpendicular to the opening planes of the main fire holes. According to the efficient combustor flame stabilizing structure, the flame stabilizing holes are formed in the length direction of the main fire holes, the roots of the main fire holes are directly heated, the flame propagation speed of the main fire holes is increased, combustion of air-fuel gas mixed gas is achieved closed to the fire opening planes, and stable combustion of flames is achieved. According to a flame stabilizing method of the flame stabilizing holes, the flame stabilizing holes and the main fire holes are perpendicularly crossed for flame stabilizing, and the flame stabilizing effect is uniform and efficient.

Description

technical field [0001] The invention relates to the technical field of burners, in particular to a flame-stabilizing structure of a high-efficiency burner. Background technique [0002] The current burner and wall-hung boiler market is fiercely competitive, and various manufacturers are trying to improve market competitiveness by reducing costs. The requirements for the burner are small volume and large heat load. Since the original burner is designed according to a certain combustion intensity, if the heat load (about 25-40%) is to be increased, it will have a great impact on the normal combustion of the burner. big. [0003] The main fire hole of the burner is the main fire hole for gas output and combustion. When the heat load is close to the maximum heat intensity of the flame hole, due to factors such as the flow rate and mixing ratio of the air and gas mixture, the flame will cause problems such as flame separation, jumping, and offset. The stability of the burner f...
