Abstract
The utility model discloses an annular fuel gas combustion tube and the manufacturing technique of the product. Most of traditional fuel gas combustion tubes are line type or square type, so fuel gas enters unsmoothly and mixes insufficiently, so energy is wasted; besides, a ring-shaped product provided with a plurality of welding nipples is greatly influenced by thermal expansion and contraction and has low safety performance. The annular fuel gas combustion tube is provided with only one external interface and comprises a combustion tube and combustion holes formed on the two sides of the combustion tube; and the two ports of the combustion tube are connected together with one end of a gas inlet through a welding nipple. Moreover, the diameter of each combustion hole is 1.3 mm, and the flame emission included angle between the two combustion holes is 55 degrees, so that flame generated during combustion can achieve an optimal heat transmission effect under the action of airflow. Therefore, not only can the fuel gas combust most sufficiently, but also the discharge of waste gas is reduced, and the dual purposes of energy conservation and promotion of environmental protection are achieved. The annular fuel gas combustion tube can be widely applied to various gas-fired combustion furnaces, bakeout furnaces, barbecue ovens and the like.
Description
Technical field
The utility model relates to a kind of combustion furnace combustion tube, particularly a kind of annular gas combustion tube.
Background technology
Existing fuel gas buring pipe unit is for guaranteeing the security and the durability of its use, generally all adopt heat resistance good, the stainless steel tube that coefficient of thermal expansion and contraction is not too big, to guarantee its security and durability in use, but because the process technology difficulty in the stainless steel tube production process is big, existing combustion tube generally all adopts ironcasting, then linear pattern or the square structures of adopting of general stainless combustion tube more, because gas combustion tube mainly is to utilize combustion gas and Air mixing to burn, straight line or square structure waste energy owing to existing the mixing dead angle to cause the fuel gas buring in the whole combustion tube insufficient when mixing gas; And minority adopts the ring-like stainless steel tube in garden, because process technology is not in place, cause a combustion tube that two above soldering openings must be arranged, soldering opening is too many, make in the combustion process of whole device, the influence of being expanded with heat and contract with cold increases, thereby makes the security performance of whole device reduce, and shorten service life.
Summary of the invention
At the problems referred to above, the utility model provides a kind of precision of doing manual work, saves the annular gas combustion tube of the energy, safety and environmental protection.
The technical scheme that its technical problem that solves the utility model adopts is: annular gas combustion tube comprises combustion tube and opens burner port in the combustion tube both sides that two ports of combustion tube link together by an end of a soldering opening and air inlet pipe.
This annular gas combustion tube, the parallel both sides of opening of burner port in combustion tube.
This annular gas combustion tube, parallel opening is set to 55 at the burner port of combustion tube both sides to the angle of combustion tube tube hub and spends.
This annular gas combustion tube, the diameter of burner port is set to 1.3mm.
This annular gas combustion tube, the distance between two burner ports on the same cambered surface is set to 4.5～5mm.
The invention has the beneficial effects as follows: the annular gas combustion tube that the present invention comes out by this special process production and processing, whole annulus has only an external tapping, effectively lower the expanded with heat and contract with cold influence of characteristic of metal product, it is more suitable to have strengthened its security performance and gas input in use greatly, and the good looking appearance practicality; In addition, because the parallel diameter of opening at the burner port of combustion tube both sides is set to 1.3mm, and the flame emission angle between two burner ports is 55 degree, both guaranteed to mix fully with air before the fuel gas buring in the combustion tube, and the flame that when burning produces can reach the heat-transfer effect an of the best under the effect of air-flow, and the distance between two burner ports on the same arc surface is set to 4.5mm～5mm, guarantee that the combustion gas in the whole combustion tube is identical with air mixing spill pressure, thereby guarantee that fuel gas buring gets fullest, discharge amount of exhaust gas is significantly reduced, reached the saving energy, promote the dual purpose of environmental protection.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples
Fig. 1 is an overall structure stereogram of the present invention;
Fig. 2 is a user mode reference diagram of the present invention;
Fig. 3 is overall structure figure of the present invention;
Fig. 4 is the side view of Fig. 3.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, annular gas combustion tube of the present invention, comprise combustion tube 1 and open burner port 3 in the combustion tube both sides, two ports of combustion tube 1 link together by an end of a soldering opening and external air inlet pipe 2, whole ring-like product has only place's plumb joint, lowered the influence of metal product suffered generation of expanding with heat and contract with cold when heating, thereby, product security performance in use guaranteed; And whole ring-like product makes air inlet more smooth and easy carrying out combustion gas when input, and combustion gas and Air mixing are more abundant, and fuel gas buring is more thorough, thereby more saves the energy, the minimizing exhaust emission.
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, annular gas combustion tube, burner port 3 walks abreast and opens in the both sides of combustion tube 1 more convenient production and processing; And parallel opening is set to 55 at the burner port 3 of combustion tube 1 both sides to the angle of combustion tube 1 tube hub and spends, and the parallel diameter of opening at the burner port 3 of combustion tube 1 both sides is set to 1.3mm, both guaranteed to mix fully with air before the fuel gas buring in the combustion tube 1, and when burning the flame that produces under the effect of air-flow, can reach the heat-transfer effect an of the best, and the distance between two burner ports 3 on the same arc surface is set to 4.5mm～5mm, guarantee that the combustion gas in the whole combustion tube 1 is identical with air mixing spill pressure, thereby guarantee that fuel gas buring gets fullest, discharge amount of exhaust gas is significantly reduced, reached the saving energy, promote the dual purpose of environmental protection.
With reference to Fig. 2, an engine firewall of adding a cover when label 4 uses for this product.
