Description
Technical field
The present invention relates to a kind of injection impeller burner, injection impeller burner be mainly used in household gas range,
In the burners of products such as commercial gas-fired stove (case), domestic gas-fired water heater.
Background technique
According to air inlet model split burner, it can be mainly divided into two major classes：One kind is injection burner, separately
One kind is air blast burner.When combustion gas heat flow is excessive, the bulky heaviness of injection burner, and blowing-type is burnt
Body product is relatively small, and air blast burner is commonly used in large scale industry boiler.
A kind of injection burner (or atmospheric burner) was illustrated by this hair tonic in 1855, is exactly that laboratory is common
Bunsen burner, this injection burner structure is simple, it is mainly by exhaust gas nozzle, ejector pipe and combustion head three parts composition,
Its working principle is：Combustion gas under a certain pressure, is projected with certain flow rate from jet pipe, and combustion gas sucks surrounding by the energy of itself
Some air in atmosphere enter ejector pipe, and combustion gas is mixed with air in ejector pipe, burn subsequently into combustion head.
Fuel gas buring is divided into completely burned and non-fully burns, and closer to completely burned, combustion thermal efficiency is higher, gives up
Gas discharge is lower, to realize that injection burner completely burned needs to meet two necessary conditions：1, combustion gas needs injection
Into required theoretical air requirement, to guarantee completely burned（Such as when natural gas completely burned, amount of natural gas and required theoretical air
The ratio of amount is 1：9.52 ）；2, combustion gas full and uniform must be mixed with by the air of injection, to guarantee gas quantity and by injection
Required theoretical air requirement is distributed in each burner port of combustion head by same ratio.
The major advantage of injection burner is：Combustion gas heat flow adjustable range is wide, and combustion gas can be burnt required with injection
Enough air are also increased or are reduced therewith by the air capacity of injection when increasing or reducing occur in gas quantity.
The protrusion of injection burner the disadvantage is that：Combustion gas with by the air of injection mainly lean on itself flow and gas laminar flow
Between molecule diffusion realize mixing, so ejector pipe near axis gas quantity is most, air capacity is minimum, from ejector pipe axis
Remoter gas quantity less, air capacity it is more, combustion gas full and uniform cannot be mixed with by the air of injection, make gas quantity and quilt
Theoretical air requirement needed for injection cannot be distributed in each burner port of combustion head by same ratio, cause each burning of combustion head
Hole burning is insufficient, and combustion thermal efficiency is low, and discharge amount of exhaust gas is high.
Although the injection burner thermal efficiency is lower, its combustion gas heat flow adjustable range is wide, flameholding, from it
Birth is widely used always so far, such as the burner inside household gas range both domestic and external at present, and use is all injection
Formula burner structure.
Summary of the invention
The combustion gas that the present invention provides a kind of in ejector pipe can full and uniform mixed injection impeller burning with air
Device.
The of the invention injection burner of being solved the problem is that：Injection burner is in burning, combustion gas and quilt
The air of injection full and uniform cannot mix, and prevent gas quantity with the theoretical air requirement needed for injection from being distributed by same ratio
In each burner port of combustion head, caused combustion thermal efficiency is low, the high technical problem of discharge amount of exhaust gas.
The technical scheme adopted by the invention is that：The injection impeller burner, including jet pipe, ejector pipe, impeller
And combustion head, ejector pipe is interior to be equipped with bracing strut, and bracing strut is equipped with impeller shaft, and impeller shaft is equipped with impeller, the blade on impeller
It is 45o with impeller axis angle, impeller can be freely rotated relative to bracing strut, and ejector pipe is to be fixedly connected with bracing strut, leaf
Wheel axis is overlapped with injection tube hub line.
Beneficial effects of the present invention, the injection impeller burner, when the combustion gas with a remote flow velocity is penetrated from jet pipe
Out with ejector pipe is entered simultaneously by the air of injection after, it is common to push the quick Stirring of impeller, make combustion gas with by injection
Air moment when passing through impeller completes full and uniform mixing, connects gas quantity with the theoretical air requirement needed for injection identical
Ratio is distributed in each burner port of combustion head, to realize completely burned.The impeller non-metallic material small using density
Material or metal material manufacture, so Impeller Mass very little, with guarantee in the case where very little air-flow is blown still can quick rotation, blade with
Between blade there are ask away from, and air supply direction when blade rotates with combustion gas and by the air-flow direction of injection consistent, institute
It is minimum on combustion gas and by the air inlet amount influence of injection with impeller, it can be ignored, the present invention is burnt to injection type is improved
The combustion thermal efficiency of device has remarkable effect, and especially to the low-pressure injection formula burner combustion thermal efficiency is improved, effect is more preferable, Er Qieshi
With property is strong, structure is simple, easily fabricated and application.
