Description
Technical field
A kind of combustion head is the utility model is related to, particularly a kind of vacuum heat-insulation central flame flame combustion head.
Background technology
Central flame flame boiler is a great deal of more in the market, and the requirement of its low NOx is in 30mg/Nm3Below.Center
The boiler that strile-backs typically uses vacuum heat-insulation, and vacuum heat-insulation refers to use condition of high vacuum degree to reach heat-insulated purpose.Vacuum heat-insulation be by
Vacuum space is extracted into 10 by the space of one cold wall and a hot wall composition, vacuum heat-insulation requirement-3-10-5Pa vacuum, from
And exclude the convection heat transfer' heat-transfer by convection of gas and most gas heat transfer.The combustion head blind area part of central flame flame boiler is inserted into
To in boiler furnace, reach effect of strile-bacing, its ignition temperature is relatively low, flame propagation speed, and burning velocity is fast.But pass
The burner for gas boiler of system using flaming combustion approach, exist combustion gas with air mixed effect temperature in poor, burner hearth
Skewness is so as to cause imperfect combustion, and the problem of content of product-nitrogen oxides is higher, not only the combustion heat is relatively low, and
And to the seriously polluted of air.
Utility model content
The purpose of this utility model is to provide a kind of vacuum heat-insulation central flame flame combustion head, and it installs simple, manufacturing cost
Low, the thermal efficiency is high, and nitrogen oxide emission is low.
To achieve the above object, the utility model takes following technical scheme：
A kind of vacuum heat-insulation central flame flame combustion head, it includes inner cylinder and outer barrel, vacuum is formed between the inner cylinder and outer barrel
Room；The inner cylinder one end connects variable-diameter joint cylinder, other end connection shower nozzle；The outside flaring of internal diameter of the variable-diameter joint cylinder, it is internal interior with this
Cylinder connection, forms coherent air duct；The air duct end connects with the air interface of the variable-diameter joint cylinder；The air duct
The interior edge air duct is axially arranged with gas connection pipe, and the combustion gas that the gas connection pipe one end is connected to the variable-diameter joint cylinder bottom connects
Mouthful, the other end is located inside the inner cylinder.
Further, the surface of the shower nozzle is porous high-temperature resistant fabric.
Further, the vacuum chamber is provided with ion probe.
Further, the gas connection pipe is located in the middle part of the inner cylinder, and side face is provided with uniform fuel gas hole.
Further, the angle in the direction of the fuel gas hole and the air duct between air-flow direction is 0-
180 degree, preferably 90 degree, 145 degree or 180 degree.
The beneficial effects of the utility model are：The utility model vacuum heat-insulation central flame flame combustion head, it installs simple, system
Low a, thermal efficiency height is caused, and nitrogen oxide emission is low.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model vacuum heat-insulation central flame flame combustion head.
Embodiment
Embodiment of the present utility model is further described below with reference to accompanying drawing.
As shown in figure 1, the utility model provides a kind of vacuum heat-insulation central flame flame combustion head, it includes inner cylinder 1 and outer barrel
2, vacuum chamber 3 is formed between the inner cylinder 1 and outer barrel 2, the vacuum chamber 3 is provided with ion probe 4.The one end of inner cylinder 1 connects variable-diameter joint
Cylinder 5, other end connection shower nozzle 6, the surface of the shower nozzle 6 is porous high-temperature resistant fabric.The internal diameter of the variable-diameter joint cylinder 5 is outside gradually
Expand, inside connects with the inner cylinder 1, forms coherent air duct.The air duct end and the air interface of the variable-diameter joint cylinder 5
51 connections.The air duct interior edge air duct is axially arranged with gas connection pipe (not shown meaning), the gas connection pipe one end
The combustion gas interface 52 of the variable-diameter joint cylinder bottom is connected to, the other end is located inside the inner cylinder 1.
The gas connection pipe is located at the middle part of inner cylinder 1, and side face is provided with uniform fuel gas hole, and the direction of the fuel gas hole is with being somebody's turn to do
Angle in air duct between air-flow direction is 0-180 degree, and in order to be well mixed with air, the angle is preferably 90
Degree, 145 degree or 180 degree.
It is natural gas and air gas mixture in inner cylinder 1 of the present utility model, unsuitable high temperature can using vacuum heat-insulation method
To reach protection inner cylinder 1 and mixed gas effect, so as to extend the service life of combustion head.
The merely exemplary explanation of above-described embodiment principle of the present utility model and its effect are new not for this practicality is limited
Type.The utility model also has many aspects to be improved on the premise of without prejudice to overall thought, any to be familiar with this technology
Personage all modifications and changes can be carried out to above-described embodiment without prejudice under spirit and scope of the present utility model.Therefore, lift
All those of ordinary skill in the art are complete without departing from the spirit disclosed in the utility model and institute under technological thought
Into all equivalent modifications or change, should be covered by claim of the present utility model.
