Abstract
The utility model relates to a double layer inner flaming type combustion apparatus, which consists of a nozzle, a blending pipe and a combustion head. The combustion apparatus is characterized in that the combustion head inside part is respectively provided with an upper cavity and a lower cavity. The center part of the combustion head is provided with an upper fire hole ring and a lower fire hole ring. The sizes of the fire rings on the upper and lower layers of fire rings, the nozzle diameter and the opening size of a wind door are arranged according to a certain ratio, which can realize the combustion effects of the upper thick ratio and the lower thin ratio. The utility model has the advantages of small volume, high thermal efficiency and meeting requirements of the environmental protection.
Description
Technical field:
The utility model relates to a kind of Gas appliance, particularly a kind of double-deck internal flame formula burner.
Background technology:
Existing burner is made up of circular burner head, mixing tube, air door, nozzle four parts.A great deal of circular vertically upward fire hole 5 is arranged above the circular burner head 7.The each several part shape is by shown in Figure 1.During burning, after combustion gas enters nozzle 1, directly spray in the mixing tube 4 by nozzle, the combustion gas kinetic energy of ejection this moment sucks primary air in the mixing tube and mixes through air door 2, primary air hole 3, air mixture enters in the cavity 6 of burner head 7 then, with after auxiliary air further mixes, participation is burnt by vertically upward circular fire hole 5 ejection.The problems of the prior art are: 1. the burner volume of equal-wattage is big, heat is not concentrated, heat loss is big, efficient is low.Since circular fire hole vertically upward, obstructions such as the dirt when easily being used, soup juice influences normal combustion, thus needs regular cleaning fire hole.3. because fire hole size distribution position vertically upward, the primary air composite rate is low, and air mixture further mixes difficulty from fire hole ejection back with auxiliary air.CO, CO in the waste gas of burning back
2, the NOx gas content is higher.Above-mentioned three big technical problems all are to be subjected to structural restriction.
Summary of the invention:
Technical problem to be solved in the utility model is: the burner volume of equal-wattage is big, heat is not concentrated, heat loss is big, efficient is low.Because circular fire hole vertically upward, obstructions such as the dirt when easily being used, soup juice influence normal combustion, so need regular cleaning fire hole.Because fire hole size distribution position vertically upward, the primary air composite rate is low, and air mixture further mixes difficulty from fire hole ejection back with auxiliary air.CO, CO in the waste gas of burning back
2, the NOx gas content is higher.Above-mentioned three big technical problems all are to be subjected to structural restriction.The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to provide a kind of double-deck internal flame formula burner, described double-deck internal flame formula burner is by nozzle, mixing tube and burning head constitute, it is characterized in that being respectively arranged with in the described burning head two cavitys up and down, the center of described burning head is provided with two fire hole circles up and down, described fire hole circle is circular, distribute on the described fire hole circle and be provided with fire hole, described fire hole is rectangular, the direction of described fire hole can be pointed to the center of circle of described fire hole circle, the direction of described fire hole also can sideward directed and the center of circle direction of described fire hole circle be 1 and spend to miter angle, two cavitys up and down of described burning head are connected with two described mixing tubes up and down respectively, described each mixing tube is connected with described nozzle, described mixing tube is provided with the primary air hole at an end that links to each other with described nozzle, described nozzle is provided with air door, concrete, the downside of described burning head also is provided with liquid holding cup.
The utility model and prior art contrast, and effect is actively and significantly, and the utility model required burner volume under equal-wattage requires is little and heat is concentrated, the thermal efficiency is high, can improve more than 5%, meets energy-conservation needs.Because fire hole is the sideward directed center of circle, be difficult for can not influenced combustion efficiency simultaneously, need not often to clean fire hole by obstructions such as dirt, soup juice.Because the fire hole while sideward directed center of circle during burning, is difficult for producing from the flame phenomenon, it is about more than 80% to improve the primary air composite rate greatly in addition.Air mixture after auxiliary air further mixes, can be fully burned after the fire hole ejection, has improved efficiency of combustion.The outstanding characteristics of the utility model are with the two-layer burning up and down of burner head part, and fire hole size and nozzle diameter and door opening degree on the two-layer up and down fire hole circle are provided with by a certain percentage, can realize the combustion efficiency of next dense light different proportion.The method can suppress to burn the back waste gas in CO, CO
2, NO especially
xThe content of gas meets the requirement in the environmental protection.
