Multi-cavity integrated combustor

Abstract

The present invention discloses one kind of integral multicavity combustor, and belongs to the field of kitchen gas burning oven. The integral multicavity combustor has spark pin, thermocouple, inner flame ring, outer flame ring, inner gas mixer, outer gas mixer, and vertical inner ejector below the inner gas mixer with nozzle in the gas inlet. It features that below the outer gas mixer, there are four or more vertical outer ejectors with nozzle in the gas inlet and each nozzle has nozzle hole in the middle part, belled gas inlet section in the lower part, belled gas outlet section in the upper part and ejecting hole communicated to the gas outlet section for replenishing air in the side wall of the upper part. The integral multicavity combustor has the advantages of high heat load, strong fire, easy to detach and wash, less contamination, capacity of being suitable for different gas sources through simply nozzle replacement, etc.

Description

technical field [0001] The invention relates to a burner for household gas stoves, in particular to a burner with a structure of multiple nozzles and multiple vertical injection pipes. Background technique [0002] Existing burner injection structures are divided into vertical injection structure and horizontal injection structure, as well as upper air inlet burner and lower air inlet burner, but no matter what type of burner it is, it is only provided with A nozzle and a corresponding ejector tube bear the gas supply load of the entire outer ring fire, so it is difficult to substantially increase the gas volume, especially the required primary air volume, so the heat load is relatively low, and it is difficult to meet the requirements of China Families, especially families in northern China, need stir-frying, especially for upward-inlet burners. Compared with lower-inlet burners, their shortcomings in this point are particularly obvious. Furthermore, due to the different c...

[0002] Existing burner injection structures are divided into vertical injection structure and horizontal injection structure, as well as upper air inlet burner and lower air inlet burner, but no matter what type of burner it is, it is only provided with A nozzle and a corresponding ejector tube bear the gas supply load of the entire outer ring fire, so it is difficult to substantially increase the gas volume, especially the required primary air volume, so the heat load is relatively low, and it is difficult to meet the requirements of China. Families, especially families in northern China, need stir-frying, especially for upward air-inflow burners, which is particularly insufficient in this regard compared with bottom-inflow burners

Furthermore, due to the different characteristics of different gas sources, the existing burners are basically designed for a certain type of gas source. Replacement of the entire burner, although there are also reports in the literature that the use of nozzles with adjustable nozzle hole parameters can achieve the purpose of replacing the burner when changing the gas source. Although it is theoretically feasible, in fact there are two problems. It is difficult to popularize and even difficult to realize. First, the range of adjustment is very small, and non-professionals cannot accurately adjust the nozzle. Therefore, for most users, it is likely that a good thing will turn into a bad thing, not only can not achieve the desired effect, On the contrary, it may cause gas waste and other adverse consequences due to improper debugging. The second is that the existing burner is generally only equipped with one nozzle and a corresponding ejector tube to bear the gas supply load of the entire outer ring fire, and for each specific As far as the ejector tube is concerned, although the amount of air it can eject can vary with the parameters of the nozzle orifice, the range of change is limited, so it is difficult to ensure the required air amount and it is difficult to achieve multi-air use. The defect of low thermal efficiency of the burner is prone to occur when the gas source is replaced
