Upside-air-inlet three-fire-ring high-power combustor

Abstract

An upside-air-inlet three-fire-ring high-power combustor comprises a burner, a distributor seat, a central fire cover, an inner-ring fire cover and an outer-ring fire cover, wherein the burner comprises an air and fuel gas pre-mixing cavity, a central gas outlet tube, an inner-ring mixing cavity, an inner-ring gas outlet connector, an outer-ring mixing cavity and an outer-ring gas outlet connector; the air and fuel gas pre-mixing cavity is positioned on the front part and is provided with a top opening; the central gas outlet tube is positioned in the center; the inner-ring mixing cavity is positioned on the right side; the outer-ring mixing cavity and the outer-ring gas outlet connector are positioned on the left side; and the central gas outlet tube, the inner-ring mixing cavity and the outer-ring mixing cavity respectively communicate with the air and fuel gas pre-mixing cavity through a central ejector tube, an inner ejector tube and an outer ejector tube. Because the structure is adopted, the top opening of the air and fuel gas pre-mixing cavity of the burner is positioned in a stove and positioned above a panel; upside air inlet is realized by primary air; an annular supporting table in the peripheral direction of the burner supports the metal panel or a bottom plate of a liquid receiving plate; secondary air enters via a gap between a distributor and the panel of the stove; and air and fuel gas are pressurized and pre-mixed in the burner, and can quickly enter the distributor seat.

Description

technical field

[0001] The invention relates to a cooker burner, in particular to a high-power burner with an upward-flowing air three-ring fire. Background technique

[0002] At present, there is a three-ring fire high-power burner, which includes a furnace head, a fire distribution seat, a central fire cover, an inner ring fire cover and an outer ring fire cover. The fire distribution seat includes a disc body, which is located on the upper surface of the center of the disc body. The central fire cover seat, the central air intake port on the lower surface communicating with the central fire cover seat, the inner axial secondary air channel surrounding the central fire cover seat, the inner ring gas groove, the inner ring air inlet port, and the outer ring gas groove , the outer ring air inlet port and the outer axial secondary air channel between the inner and outer ring gas grooves; Outer ring gas groove fits. The problem is that the upward air intake cannot be realize...
