Blockage-proof central fire cover and combustor adopting central fire cover

Abstract

Disclosed is a blockage-proof central fire cover. The blockage-proof central fire cover comprises a barrel (2) and an end cap (1) arranged or integrally formed on the barrel (2), and fire holes (21) are formed in the surrounding wall of the barrel (2). The blockage-proof central fire cover is characterized in that a blocking ring (11) which limits overflowing of overflow liquid is disposed around the edge of the top surface of the end cap (1); the blocking ring (11) is provided with at least one flow guide opening (12) which guides the overflow liquid to flow out of the end cap (1); flanges (22) which protrude out of the side wall of the barrel (2) are disposed around the fire holes (21) of the barrel (2); the outer side surfaces of the flanges (22) form flow guide surfaces (25) which can bear the overflow liquid flowing out of the flow guide openings (12); and the flow guide surfaces (25) are located below the flow guide openings (12). The invention further discloses a combustor adopting the central fire cover. Compared with the prior art, the blockage-proof central fire cover and the combustor adopting the central fire cover have the advantages that by arranging the flanges, the functions of blockage prevention, easy cleaning and high thermal efficiency are achieved.

Description

technical field [0001] The invention relates to a component of a burner, in particular to a center fire cover of the burner, and the invention also discloses a burner applied with the center fire cover. Background technique [0002] The current atmospheric burner is usually a single-ring fire cover or two inner and outer rings, together with ignition needles, thermocouples (or ion induction needles with the same function) and other components to achieve the functions of generating flame and maintaining flame. [0003] The surface of the traditional single-ring fire cover or the inner ring fire cover of the two fire covers of the inner and outer rings has the risk of water at the bottom of the pot and long-term oil stains on the bottom of the pot entering the flame hole and blocking the fire cover hole. There are many public documents of this type of fire cover, such as the Chinese utility model patent "A central fire cover for gas stoves" with the patent number of ZL20072031...

AI Technical Summary

Problems solved by technology

However, in the actual application process, we found that the overflow liquid flowing out of the opening still passes through the fire hole along the lower edge, and there is a possibility of blockage, which cannot completely solve the problem of the fire hole blockage
