Problems solved by technology

A problem with the construction of conventional flame hole components is that deformation due to thermal stress may cause distortion of the burning surface or change in the shape of the flame hole, resulting in insufficient combustion or flashback
In this case, when the flame temperature drops, incomplete combustion will occur, producing a large amount of pollutants such as carbon monoxide

Abstract

The present invention is directed to a fire hole part structure of a gas burner, which is constructed to be manufactured at a low cost, can improve flame stability, and can prevent incomplete combustion due to the length of flame. The structure is provided to a premixing ignition burner, which is installed to apply heat to a heat exchanger of a boiler, and includes fire hole pieces (20) which are installed parallel to one another in mounting openings (13) of a burner body (11), and each of which is defined with fire holes (23) at regular intervals. An upper wall (21) of at least one of the fire hole pieces (20) is bent or curved to extend in at least two directions, and the fire holes (23) are defined through respective surface portions of the upper wall (21), which extend in different directions, to face different directions.

Description

technical field [0001] The invention relates to a fire hole component structure of a gas burner, which can improve the stability of the flame and reduce the products produced by incomplete combustion by impinging the flame into the fire hole. Background technique [0002] As a gas burner for a boiler or water heating system, the Bunsen burner is the burner used in the past; but the pre-mixed ignition type burner is currently the main one because it can reduce the generation of pollutants and reduce the size of the combustion chamber. burner. [0003] The premix ignition type burner has a fire hole part in which a plurality of fire holes for injecting a mixture of fuel gas and air for generating a flame are provided. Conventional firehole components have a structure in which the firehole passes through a single plate element comprising a flat or cylindrical plate. The conventional flame hole member structure has a problem in that deformation due to thermal stress may cause ...
