Convex hole plate type combustor

Abstract

The invention discloses a convex hole plate type combustor which comprises an upper convex hole plate and a lower convex hole plate, wherein the plate edges of the upper convex hole plate and the plate edges of the lower convex hole plate are sealed to form a cavity. The upper convex hole plate and the lower convex hole plate are provided with a plurality of upper boss holes and a plurality of lower boss holes respectively, the upper boss holes correspond to the lower boss holes, and the opposite ports of the lower boss holes are sleeved with the opposite ports of the upper boss holes to form a first annular hole between the upper boss holes and the lower boss holes. The convex hole plate type combustor is provided with a rectifying panel arranged on the upper side of the upper convex hole plate in a combining mode, concave boss holes corresponding to the upper boss holes are formed in the rectifying panel, the opposite ports of the upper boss holes are sleeved with the opposite ports of the concave boss holes to form second annular holes between the upper boss holes and the concave boss holes, and a plurality of air inlet through holes are formed in the side wall of the rectifying panel. Two sets of opposite ejectors are fixed at the bottom of the lower convex hole plate in a two-side mode, the two sets of ejectors are provided with opposite ejecting holes, the opposite ports of the opposite ejecting holes are inlets, and the other ends of the ejecting holes are communicated with the cavity between the upper convex hole plates and the lower convex hole plates.

Description

technical field [0001] The invention relates to a burner suitable for gas water heaters and gas wall-hung boilers. Background technique [0002] Currently used gas water heater burners and wall-hung boiler burners generally use T-shaped burners and harmonica-type burners. The combustion power is not high; in terms of environmental protection, due to the unilateral mixing of the combustion hole with the secondary air, poor combustion occurs at high power output, the combustion flame is larger, the temperature of the flame center is higher, and the contact area between the high-temperature flame and oxygen is smaller. Larger, more temperature-type NO is produced. Contents of the invention [0003] The technical problem to be solved by the present invention is to improve the deficiencies of existing burners and provide a new type of convex-hole plate burner with simple structure, fewer processing and assembly procedures, high combustion efficiency, large unit combustion powe...
