Description
Technical field
This utility model is related to a kind of boiler.Specifically related to a kind of self-contained high efficiency fuel with expansion furnace（Gas）Water bath
Stove.Category heating equipment technical field.
Background technology
In recent years, as oil-burning gas-fired boiler compact conformation, high degree of automation, easy for installation, exhaust emission are little, and
Can obtain very convenient under various heating agents and flexibly apply, oil-burning gas-fired boiler has obtained extensive development and application.
Common self-contained fuel oil currently on the market（Gas）Boiler mostly is double drum longitudinal D type stoves, i.e., burner hearth is in convection tube
On the left of beam or right side.Fuel generates high-temperature flue gas after hearth combustion, turns from burner hearth afterbody and is changed into convection bank
Heat, then again through back-end surfaces（Economizer, condenser）Discharge after further exchanging heat.As fuel combustion is to combustion space
Have certain requirement, add and occupy certain space positioned at the convection current heat affected zone of burner hearth side, boiler width size compared with
Greatly, restriction of the road transport to boiler width, cause that self-contained boiler can not be done on tonnage are too big.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of the self-contained of expansion furnace for above-mentioned prior art
Fuel oil（Gas）Hot-water boiler, by reasonable heating surface and flow scheme design, is minimized boiler width, and furnace cavity is added
Greatly, break through restriction of the road transport to boiler overall dimensions and combustibility.
The technical scheme in the invention for solving the above technical problem is：A kind of self-contained gas and hot water pot of expansion furnace
Stove, it includes the burner hearth on front side of boiler, the convective region on rear side of boiler, economizer and burner, the burner hearth by it is upper,
Lower header connects left and right membrane wall, and forward and backward membrane type connects upper and lower header, the burner hearth after the connection of upper and lower collector again
Rear membrane wall be connected with convective region, the burner is installed on the prepattern wall of burner hearth, and the convective region is by four facial films
Formula wall and the flag formula convection bank composition being connected with membrane wall, four sides membrane wall constitute the passage that flue gas is flowed up, and convection current
The top in area is connected with economizer by flue.
Preferably, the economizer is made using the resistant material with extended surface, mainly includes economizer header
And coil, the water inlet and outlet of the coil are collected by economizer header, while spiral is provided with coil
Fin.
Compared with prior art, the utility model has the advantage of：
1st, pressurized firing is realized, the thermal efficiency is high：Boiler body full film type wall seal, save boiler brickwork and every
Wall, it is ensured that the overall sealing property of boiler, without leaking out, realizes pressurized firing so that furnace flame degree of filling is good, exchanges heat
Fully, heat loss is little, and need not arrange air-introduced machine.
2nd, overall to dispatch from the factory, installation period is short：Save the brickwork and partition wall of boiler, compact conformation, single backhaul flag formula pair
Flowing bundle structure, boiler width are little, and boiler integrally dispatches from the factory, without the need for carrying out welding assembly in building site.
3rd, using the economizer of Influences of Structure of Spiral Finned Tube, small volume, good looking appearance.External economizer, changes installation side
Just.In order to prevent cold end corrosion from processing using special ND Steel materials and anticorrosion of flue duct, service life is substantially increased.
4th, by reasonable heating surface and flow scheme design, boiler width is reduced, increases length, economizer can be arranged in top
Portion or side, flexible arrangement, adaptive surface are also wider.

Specific embodiment
This utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in Fig. 1-6, the self-contained gas-fired water heating boiler of a kind of expansion furnace in the present embodiment, including positioned at boiler
The burner hearth 1 of front side, the convective region 2 on rear side of boiler, economizer 3 and burner 4, lead between the convective region 2 and economizer 3
Cross flue 5 to connect, boiler furnace separated with convective region, burner hearth is placed on before boiler, convective region is placed on burner hearth rear portion,
It is middle to be connected by flue.This design reduces boiler overall width, while increasing furnace cavity, not only reduces boiler to accounting for
The requirement of ground width, is also beneficial to fuel combustion.
The burner hearth 1 by upper collecting chamber 1.1, lower header 1.2, upper collector 1.3, lower collector 1.4, prepattern wall 1.5, after
Membrane wall 1.6, left membrane wall 1.7 and right membrane wall 1.8 are constituted, the longitudinal cloth of the upper collecting chamber 1.1 and lower header 1.2 along burner hearth
Put, and left membrane wall 1.7 and right membrane wall 1.8 are connected with upper collecting chamber 1.1 and lower header 1.2 respectively, 1.3 He of upper collector
Lateral arrangement of the lower collector 1.4 along burner hearth, and prepattern wall 1.5 and rear membrane wall 1.6 are respectively by upper collector 1.3 and lower remittance
Header 1.4 is collected, and the upper collector 1.3 and lower collector 1.4 are connected with upper collecting chamber 1.1 and lower header 1.2 respectively, hearth zone
Upper collecting chamber is supported by membrane wall pipe.Full film type wall seals water-cooled wallflow into furnace combustion zone.Membrane wall leaves outlet flue afterwards so that
Burner hearth 1 is connected with convective region 2, and the burner 4 is installed on the prepattern wall of burner hearth 1.
The convective region 2 adopts four sides membrane wall shape of the mouth as one speaks arrangement, and it is logical that membrane wall composition flue gas in four sides is flowed up
Road, is disposed with flag formula convection bank 2.1 on the membrane wall of the convective region 2, improves convective region compactness, makes flue gas vertical
Flow up, back-end surfaces are arranged in into convective region top, reduce the total length of boiler as far as possible, the convective region 2
Top outlet flue is connected with the economizer 3 of top or side by flue 5.
The economizer 3 is made using the resistant material with extended surface, mainly includes economizer header 3.1 and Serpentiss
Shape pipe 3.2, the water inlet and outlet of the coil 3.2 are collected by economizer header 3.1, while setting on coil 3.2
Helical fin 3.3 is equipped with, the coal economizer structure can substantially reduce the temperature of flue gas.
The flue gas produced after burner combustion sequentially pass through burner hearth, convection bank, economizer drop to less than 90 DEG C enter it is big
Gas.
