Description
Technical field
The present invention relates to gas heater field more particularly to combustion gas square tubes, combustion system and gas heater.
Background technique
Existing gas heater square tube assembly, is assembled by square tube and nozzle, and square tube is aluminium casting, the corresponding peace of processing thereon
The threaded hole of nozzle is filled, processes corresponding external screw thread on nozzle, square tube and nozzle are through being threaded togather.The patent No.
CN201820222534.2, the Chinese patent of a kind of entitled assembly machine and gas heater, discloses: the guidance set with
The positioning component connection, for the nozzle to be sent to the positioning component；The positioning component and the glue spreading assembly
It is oppositely arranged, for the nozzle to be fixed at the glue spreading assembly；The glue spreading assembly is used for the screw thread of the nozzle
Portion's gluing；The fixation kit is for fixing the square tube；The positioning component is also used to drive the nozzle to close to described
The direction of fixation kit moves, and the threaded hole of the threaded portion and the square tube that make the nozzle cooperates, with assemble the nozzle and
The square tube, technical solution.
Square tube assembly in the prior art, the junction of square tube and nozzle, due to glue aging, glue it is coated it is uneven,
The screw thread factors such as get rusty also need to hunt leak, cause production process more there are gas leakage hidden danger after square tube and nozzle assembly.
Summary of the invention
The technical problem to be solved by the present invention is providing a kind of combustion gas square tube and gas heater, above-mentioned square tube is solved
There are gas leakage hidden danger, the more problems of square tube assembly production process with the junction of nozzle.
The solution that the present invention solves its technical problem is:
Combustion gas square tube, including square tube main body, the square tube main body is interior to be equipped with gas flow, and the square tube main body is equipped with spray
Stomata, the fumarole are connected to the gas flow, and the square tube main body is integrally formed.
Square tube main body is integrally formed with the effect of nozzle, without assembling nozzle, reduces production process, reduce
Security risk；Also there is the benefit for simplifying stock control and production allotment.Jet can be cast out simultaneously when casting square tube main body
Hole can also process fumarole by the method to drill in the square tube main body cast out.
Further, the gas flow includes main channel and air channel, and the section of the air channel is trapezoidal, described logical
The upper end of air drain is narrower than the lower end of the air channel, and the lower end of the fumarole is connected to the upper end of the air channel.The spray
Stomata cylindrical form.
In gas heater, the thermic load of single-nozzle output is calculated by following formula:
Wherein, the thermic load of q- single-nozzle output；U- nozzle orifice coeficient；D- nozzle diameter；D- combustion gas relative density；
Gaseous-pressure before H- nozzle；Hi- combustion gas low heat value.Since d, Hi are definite value, industry has particular requirement to the value of H, according to requiring
Gaseous-pressure before control nozzle, it is known that, as long as the value of u is constant, that is, it can guarantee that the size of q is constant.
In the nozzle of the prior art, angle of throat a1, depth L1And diameter D1It is the parameter for influencing discharge coefficient u, L1/D1≤2
When, u value is with L1/D1Increase and also slightly increases, L1/D1When > 2, u value is with L1/D1Increase and slightly subtract, usually takes in the design
L1/D1It is 1~2, angle of throat a1At 15 °~30 °, u reaches maximum value.
The discharge coefficient u of square tube of the invention, by the angle a of the two sidewalls of air channel2, jet hole depth L2, diameter D2Certainly
It is fixed.Therefore, it is possible to pass through control a2、L2、D2Value, the thermic load to guarantee that fumarole in square tube of the invention exports can reach
Identical to the thermic load exported with nozzle in the prior art, it is total that square tube of the invention can replace square tube in the prior art
At.
Further, the cast technique of the square tube main body is integrally formed.Molten metal is injected in mold, square tube is cast as
A possibility that main body, this one-time formed square tube main body gas leakage very little, the square tube being threadedly coupled than in the prior art and nozzle
The airtight effect of the square tube assembly of composition is superior, it might even be possible to save one of leak detection process.
Optionally, the material of the square tube main body be aluminium, copper, steel, aluminium alloy, kirsite, magnesium alloy or steel alloy, preferably
For aluminium.
Optionally, including at least two rows of gas flows, the fumarole on two rows of airflow channels is used to form two rows of fire
Flame.Obstructed mutually between gas flow, combustion gas enters from gas flow, burns from fumarole ejection, it is two rows of or it is two rows of with
On fumarole can be respectively used to injection thick and thin flame, realize thick and thin flame separation.
The present invention also provides combustion system, including burning chamber shell, the combustion gas square tube is set to the burning chamber shell
In, it further include the blower that the combustion chamber is connected to from bottom, the exhaust passage for being connected to from top the combustion chamber.The combustion system
Gas leakage probability it is small, it is safe, durable.
The present invention also mentions gas heater, further includes shell including the combustion system, and the combustion system is set to institute
It states in shell.
The present invention also mentions gas heater, including the combustion gas square tube.
The beneficial effects of the present invention are: effect of the square tube main body with nozzle, is integrally formed, without assembling nozzle, have
The benefit for being reduced production process, reducing security risk, simplify stock control, simplifying production allotment.
