Abstract
The utility model discloses a kind of low-temperature smoke extraction boiler, including: body of heater；Flue and heat exchanger it is provided with in described body of heater；Described heat exchanger is arranged on the outer top of described flue；Described flue inner top is provided with finned tube；Described finned tube includes fin and body；Described fin is axially uniformly arranged on described tube wall along described body；Described body connects with described heat exchanger.This utility model by increasing fin at flue top, and flue top arranges heat exchanger so that the recirculated water of smoke discharging residual heat heating heat exchanger, thus reduces exhaust gas temperature, and exhaust gas temperature is less than 100 DEG C, adds the thermal efficiency of boiler.
Description
Technical field
This utility model relates to field of boilers, particularly relates to a kind of low-temperature smoke extraction boiler.
Background technology
Coal is the main energy sources of China, accounts for more than the 70% of China's primary energy total quantity consumed, during current China uses
Industrial Boiler about 50.4 ten thousand, 1,260,000 steam ton, and it is 1/3rd that annual consumption raw coal accounts for gross annual output amount.At non-renewable energy resources
Today that day is becoming tight, consumption reduction of economizing on coal has become the key subjects that boiler industry faces.On the other hand realize along with environmental protection
Reinforcement, reduce pollute reduce soot emissions the most urgently put in face of us.
Generally there is high fume temperature in traditional boiler so that energy utilization rate is low, and waste is serious.The most middle-size and small-size pot
Stove quantity is big, consumes height, and evenly heat efficiency only has more than 50%, and the energy of nearly half is wasted.
Utility model content
Not enough for prior art, this utility model provides a kind of low-temperature smoke extraction boiler, it is possible to reduce exhaust gas temperature,
Improve energy utilization rate.
In view of this, the following technical scheme of this utility model offer:
A kind of low-temperature smoke extraction boiler, including:
Body of heater；
Flue and heat exchanger it is provided with in described body of heater；Described heat exchanger is arranged on the outer top of described flue；Described flue
Inner top is provided with finned tube；
Described finned tube includes fin and body；Described fin is axially uniformly arranged on described tube wall along described body
On；Described body connects with described heat exchanger.
Preferably, described finned tube is arranged in parallel in described flue inner top at certain intervals.
Preferably, the structure of described fin is plain fin, saw tooth fin or corrugated fin.
Preferably, described inner surface of tube body is covered with corrosion resistant coating.
From technique scheme it can be seen that this utility model provide low-temperature smoke extraction boiler, by flue top increase
Adding finned tube, flue top arranges heat exchanger so that the recirculated water of smoke discharging residual heat heating heat exchanger, thus reduces exhaust gas temperature,
Exhaust gas temperature is less than 100 DEG C, adds the thermal efficiency of boiler.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
As shown in Figures 1 to 3, a kind of low-temperature smoke extraction boiler that this utility model provides, including: body of heater 1；Arrange in body of heater 1
There are flue 2 and heat exchanger 3；Heat exchanger 3 is arranged on the outer top of flue 2；Flue 2 inner top is provided with finned tube 4；Finned tube 4 wraps
Include fin 401 and body 402；Fin 401 is axially uniformly arranged on body 402 outer wall along described body 402；Body 402 with
Heat exchanger 3 connects.
In technique scheme, the outer top heat exchanger of flue 23, it is possible to make finned tube 4 keep low temperature state, thus reduce
The temperature of flue gas；The finned tube 4 of flue 2 inner top can carry out secondary heat exchange with flue gas such that it is able to reduces exhaust gas temperature, increases
Add the thermal efficiency of boiler, and then reach energy-conservation purpose.
In the present embodiment, in order to improve energy utilization rate further, air conservation discharge exceeds standard, finned tube 4
It is arranged in parallel in described flue 2 top at certain intervals.
In the present embodiment, fin 401 is plain fin, saw tooth fin or corrugated fin.
In the present embodiment, in order to improve the antiseptic property of finned tube 4, and then the service life of raising boiler, body
Corrosion resistant coating it is coated with in 402.
The low-temperature smoke extraction boiler that this utility model provides, by increasing finned tube 4 at flue 2 top, flue 2 top is arranged
Heat exchanger 3 so that the recirculated water of smoke discharging residual heat heating heat exchanger 3, thus reduce exhaust gas temperature, exhaust gas temperature is less than 100 DEG C, increases
Add the thermal efficiency of boiler.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses this practicality new
Type.Multiple amendment to these embodiments will be apparent from for those skilled in the art, is determined herein
The General Principle of justice can realize in the case of without departing from spirit or scope of the present utility model in other embodiments.Cause
This, this utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The widest scope consistent with novel features.
