Description
Technical field
The utility model is related to a kind of boiler component, more particularly to a kind of air preheater.
Background technology
To blast combustion chamber by blower fan in burning combustion-supporting for boiler in the prior art, because combustion chamber belongs to high-temperature region
Domain, the air into the region, which may require that, consumes a part of heat, and then has had influence on efficiency of combustion, while during boiler combustion
The a large amount of flue gases produced are discharged into air, have wasted energy.
Utility model content
In order to solve problem present in background technology, the utility model provides a kind of air preheater of boiler,
The hot preheated air of tail produced by using boiler combustion, improves efficiency of combustion, reduces disposal of pollutants.
To reach above-mentioned purpose, the utility model is adopted the following technical scheme that：
A kind of air preheater of boiler, including preheating zone, preheating zone pass through the bent passage of bottom and changing for boiler
Hot-zone is connected, it is characterised in that the top sidewall of preheating zone is connected with blower fan by airduct, and the bottom sidewall of preheating zone is provided with
Air outlet, air outlet is connected with preheated air pipe, and preheated air pipe is connected with the burner of boiler body, is set in preheating zone
Have and be staggered between multilayer division board, levels division board, form the pre- hot-flow flue of bending；
Smokejack is provided with the top of preheating zone, preheating zone center is provided with heat exchanger tube, and heat exchanger tube extends down into bending
In passage, extend upwardly into smokejack.
The preheating zone is vertical strip passage.
The preheating zone is that closing is connected with bent passage connecting place with smokejack connecting place and preheating zone.
The burner of boiler body includes being provided with igniter in igniting chamber, igniting chamber, preheated air pipe and igniting chamber
Communicate.
Fuel feed pump is provided with the side wall of igniting chamber, fuel feed pump is connected with oil conservator.
The beneficial effects of the utility model are：
Brief description of the drawings
The utility model is further illustrated below in conjunction with the accompanying drawings
Fig. 1 is the overall structure diagram of air preheater described in the utility model；
Embodiment
Explanation and embodiment are further described to the utility model below in conjunction with the accompanying drawings：
Embodiment 1
As Fig. 1 illustrates a kind of boiler, the boiler has boiler body 1, and the bottom of boiler body 1 is combustion chamber 2, burning
The top of room 2 is connected with heat transfer zone 13 by heat exchanger channels 10, and heat transfer zone 13 is provided with superheater 12 with heat exchanger channels 10.
The bottom of heat transfer zone 13 is connected with air preheater by bent passage, and preheating device includes preheating zone 15, preheating
Area 15 is vertical strip passage, and the side wall at the top of it is connected with blower fan 18 by airduct, and the side wall of its bottom is provided with air-out
Mouthful, air outlet is connected with preheated air pipe 17.Preheated air pipe 17 is connected with the burner 3 of boiler body 1.Burner bag
Include and igniter 4 is provided with igniting chamber 5, igniting chamber 5, preheated air pipe 17 is communicated with igniting chamber 5, is set on the side wall for chamber 5 of lighting a fire
Fuel feed pump 6 is equipped with, fuel feed pump 6 is connected with oil conservator 7.
The top of preheating zone 15 is provided with smokejack 14, and the center of preheating zone 15 is provided with heat exchanger tube 19, and heat exchanger tube 19 is downward
It extend into bent passage, extends upwardly into smokejack 14.
It is provided between multilayer division board 16, levels division board 16 and is staggered in preheating zone, thus form bending
Pre- hot-flow flue.
The air of heat transfer zone 15 is blown into from blower fan 18, and advance is bent in pre- hot-flow flue, it is empty by the heat exchange of heat exchanger tube 19
Gas is preheated to more than 200 DEG C, is then entered by preheated air pipe 17 in igniting chamber 3, and igniting chamber 3 is sprayed into from fuel feed pump 6
In fuel oil burnt in the presence of high-temperature preheated air, due to the effect by preheated air so that fuel oil burning it is more steady
It is fixed and more efficient.Flue gas after burning is again introduced into preheating zone 15 by heat exchange by heat exchanger channels 10 and heat transfer zone 13
Discharged afterwards from smokejack 14.
By being preheated to the air into chamber of lighting a fire, on the one hand cause the more abundant of fuel oil burning, reduce pollution
The generation of thing, on the other hand takes full advantage of tail heat, has saved the energy again.
It will be recognized by those skilled in the art, can be to above-mentioned on the premise of without departing from protection scope of the present invention
Embodiment carries out various modifications, change and combined, and thinks that this modification, change and combination are the models in originality thought
Within enclosing.
