Abstract
Flame condensing boiler is returned at a kind of two return center, belongs to boiler technology field.It includes boiler shell and combustor, the boiler shell lumen centers partial below sets corrugated internal furnace, the corrugated internal furnace front end sets return combustion chamber, the return combustion chamber front end communicates with combustor, the return combustion chamber rear end communicates with corrugated internal furnace, and the corrugated internal furnace periphery is threaded smoke pipe, and the threaded flue front end communicates with return combustion chamber, the threaded flue rear end communicates with rear smoke box, and the rear smoke box communicates with chimney.The restriction that the utility model passes through said structure so that Fuel Consumption is far below conventional gas boiler, and the thermal efficiency greatly reduces greenhouse gases and nitrogen oxide emission, so as to realize energy-efficient and environmentally friendly purpose up to more than 98%.
Description
Technical field
The utility model belongs to boiler technology field, and in particular to flame condensing boiler is returned at a kind of two return center.
Background technology
With raising of the country to environmental requirement, natural gas as clean fuel be recent years development main flow, three times
Journey gas fired-boiler is at present in the leading products with combustion of natural gas boiler.Existing three backhauls gas fired-boiler is due to by structure
Limitation, the thermal efficiency is generally 92% or so, 140 DEG C or so of exhaust gas temperature, and greenhouse gases be present and nitrogen oxide emission is big
The shortcomings of.Further reduce the discharge of greenhouse gases and nitrogen oxides and improve boiler thermal output and subtract as current boiler energy-saving
The developing direction of row.
Utility model content
The problem of existing for prior art, the purpose of this utility model, which is to design, provides a kind of two return center Hui Yan
The technical scheme of condensing boiler.
Return flame condensing boiler at a kind of described two return center, including boiler shell and combustor, it is characterised in that described
Boiler shell lumen centers partial below sets corrugated internal furnace, and the corrugated internal furnace front end sets return combustion chamber, the return combustion chamber front end
Communicated with combustor, the return combustion chamber rear end communicates with corrugated internal furnace, and the corrugated internal furnace periphery is threaded smoke pipe, the spiral shell
Line smoke pipe front end communicates with return combustion chamber, and the threaded flue rear end communicates with rear smoke box, and the rear smoke box communicates with chimney.
Flame condensing boiler is returned at a kind of described two return center, it is characterised in that the corrugated internal furnace periphery sets two layers of spiral shell
Line smoke pipe.
Flame condensing boiler is returned at a kind of described two return center, it is characterised in that the flue after described between smoke box and chimney
On be sequentially provided with energy-saving appliance and condenser.
Flame condensing boiler is returned at a kind of above-mentioned two return center, and by fuel, the pressure combustion in corrugated internal furnace forms height at a high speed
Warm fire flame, under the backflow Involving velocity of high-speed flame, high-temperature flue gas is back to return combustion chamber from corrugated internal furnace afterbody, enters back into spiral shell
Line smoke pipe is fully exchanged heat, then by being discharged into air after energy-saving appliance, the heat exchange of condenser twin-stage.The utility model uses ripple
The design of flue, enhances radiation heat transfer, because high-speed flame is to the Involving velocity of backflow, reduces the temperature of flame, can have
Effect suppresses the generation of nitrogen oxygen compound；Corrugated internal furnace front end sets return combustion chamber, may be such that smoke pipe is tight along flue periphery arrangement
Gather；The setting of front smoke box is eliminated, solves the problems, such as that the too high radiation loss of boiler front smoke box temperature is big；Using one way screw thread cigarette
Pipe is arranged, can reduce flue gas resistance, improves energy utilization rate；Afterbody energy-saving appliance is placed in rear smoke box, can reduce boiler volume,
Solves the problems, such as the limitation of user place；By energy-saving appliance, condenser twin-stage exchange heat, can make exhaust gas temperature control 65 DEG C with
It is interior.The restriction that the utility model passes through said structure so that Fuel Consumption is far below conventional gas boiler, and the thermal efficiency is reachable
More than 98%, greenhouse gases and nitrogen oxide emission are greatly reduced, so as to realize energy-efficient and environmentally friendly purpose.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1- boiler shells；2- threaded flues；3- corrugated internal furnaces；Smoke box after 4-；5- energy-saving appliances；6- condensers；7- cigarettes
Chimney；8- return combustion chambers；9- combustor joints；10- combustors.
Embodiment
The utility model is further illustrated below in conjunction with Figure of description.
As illustrated, flame condensing boiler is returned at a kind of two return center includes boiler shell 1 and combustor 10, combustor 10 is logical
Cross the combustor joint 9 set to be fixed on boiler shell 1, the lumen centers partial below of boiler shell 1 sets corrugated internal furnace 3, ripple
The furnace wall of line flue 3 is ripple struction, and the front end of corrugated internal furnace 3 sets return combustion chamber 8, and the front end of return combustion chamber 8 communicates with combustor 10, returns
The combustion rear end of room 8 communicates with corrugated internal furnace 3, and the periphery of corrugated internal furnace 3 is threaded smoke pipe 2, preferably, the periphery of corrugated internal furnace 3 is set
Two layers of threaded flue 2 is put, the front end of threaded flue 2 communicates with return combustion chamber 8, and the rear end of threaded flue 2 communicates with rear smoke box 4, rear smoke box 4
Communicated with chimney 7, energy-saving appliance 5 and condenser 6 are sequentially provided with the flue between rear smoke box 4 and chimney 7.
During work, combustor 10 works, and fuel pressure combustion in corrugated internal furnace 3 forms high-speed and high-temperature flame, at a high speed
Under the backflow Involving velocity of flame, high-temperature flue gas is back to return combustion chamber 8 from the afterbody of corrugated internal furnace 3, enters back into threaded flue 2 and carries out
Fully heat exchange, then by being discharged into air after energy-saving appliance 5, the heat exchange of the twin-stage of condenser 6.
Finally it should be noted that：Various embodiments above is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, either to which part or whole
Technical characteristic carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
The scope of each embodiment technical scheme of type.
