Abstract
The utility model discloses a kind of biological mass gas burnnig boiler condenser, stainless steel extended surface tube of the condenser pipe group by carbon steel elbow and as heating surface is welded to form, generally S-shaped layout；The stainless steel extended surface tube passes through flue coaming plate.Using stainless steel extended surface tube as heating surface tube group, and pipe row's spacing arranges the combustion characteristics with fin length and width and its equal adapted biomass combustion gas of line space design, the shortcomings that overcoming more ashes after biomass high-temperature fuel gas buring and easily blocking heating surface can make boiler entirety thermal efficiency ratio without improving 8~13% when taking any waste heat recovery measure.
Description
Technical field
The utility model belongs to boiler auxiliaries, is specifically related to a kind of biological mass gas burnnig boiler tail flue gas waste heat and returns
The equipment of receipts.
Background technology
The fuel of biological mass gas burnnig boiler is mostly biomass high-temperature gasification gas, using crushed biomass such as chips, wood
Bits etc. gasify, and crushed biomass moisture is even as high as 30% substantially more than 10% so that in high-temperature gasification gas
Containing a large amount of water vapour, rich in the latent heat of vaporization.When exhaust gas temperature is higher, water vapour cannot condense releasing heat, but with
Flue gas emission, heat are wasted, meanwhile, high-temperature flue gas also takes away a large amount of thermal energy, forms larger smoke evacuation energy loss together.
The tail flue gas of standard biologic matter gas fired-boiler is higher at present, has 130~180 DEG C, most of no input flue gases
Waste heat of condensation reclaimer causes the waste of the energy；Some use stainless steel spiral ribbed pipe type condenser, spiral-finned tube
There is guiding to flow of flue gas, cause its uneven and disorderly, easily cause dust stratification and the blocking of flue gas, influence the normal fortune of boiler
Row；Some use stainless steel bare tube formula condenser, although the problem of overcoming dust stratification and blocking, manufacture cost is very high.
Utility model content
The utility model proposes regarding to the issue above, provides a kind of biomass fuel steam pot of high efficiente callback fume afterheat
Furnace cooling condenser.
The technical scheme in the invention for solving the above technical problem is as follows：A kind of biological mass gas burnnig boiler condenser,
Including import header, condenser pipe group, insulating layer, shell, outlet header and the frame with flue coaming plate, condenser pipe group and import
Mailbox is connected with outlet header, and insulating layer is surrounded on frame surrounding, and shell surrounds insulating layer, and the condenser pipe group is curved by carbon steel
Head and the stainless steel extended surface tube as heating surface are welded to form, generally S-shaped layout；The stainless steel extended surface tube passes through flue
Coaming plate.
Further, the stainless steel extended surface tube is by stainless steel tube and several pieces of fins for being distributed in stainless steel tube lateral wall
It forms.
The fin is arranged symmetrically in couples.
The fin radial clearance is 8mm, and the spacing of axially adjacent fin is 23mm.
Compared with prior art, due to using stainless steel extended surface tube as heating surface tube group, and pipe row's spacing is arranged and fin
Piece length and width and its combustion characteristics of the equal adapted biomass combustion gas of line space design, overcome more ashes after biomass high-temperature fuel gas buring and
The shortcomings that easily blocking heating surface, while can be cooled to 130~180 DEG C of flue gas condensings of biological mass gas burnnig boiler tail portion higher temperatures
40~50 DEG C, absorb flue gas in sensible heat and condensation heat, carry out waste heat recovery, can make boiler entirety thermal efficiency ratio without take appoint
8~13% are improved during what waste heat recovery measure；The easy dust stratification of biological mass gas burnnig boiler is overcome the problems, such as simultaneously and is blocked, and reduces system
This is caused, manufacture cost saves about 30% than conventional stainless steel bare tube formula condenser.Extended surface tube has current sharing and fair current
Property, the flying dust in flue gas can pass through, and not easily cause dust stratification；Extended surface tube is accumulated with extended surface, than conventional light pipe section
Manufacture cost is reduced in material saving.

Fig. 2 is stainless steel extended surface tube schematic diagram.
Fig. 3 is the sectional view of Fig. 2.
Specific embodiment
As shown in Figure 1, biological mass gas burnnig boiler condenser is mounted on biological mass gas burnnig boiler tail portion, biological mass gas burnnig boiler
Condenser includes：Import header 1, condenser pipe group 2, insulating layer 3, shell 4, outlet header 5 and frame 6.Water system inlet tube and outlet tube
Import header and outlet header are connected respectively；Flue gas is introduced from top, bottom discharge.Flue gas and boiler working media (water) are logical
It crosses condenser pipe group and carries out heat exchange.
Frame 6 is made of upper flange 61, flue coaming plate 62 and lower flange 63, and all components of condenser are fixed entirely by frame
And support.Upper flange 61, flue coaming plate 62 and lower flange 63 by stainless steel clad plate bending, be welded, stainless steel cladding
Be arranged in inside, using stainless steel clad plate, can anti-low-temperature corrosion and all steel plate dramatically save material into
This.
Import header 1 and the pipe comb mouth of 2 lower part of condenser pipe group weld, and outlet header 5 and the pipe on 2 top of condenser pipe group are arranged
Nozzle welds.
Condenser pipe group 2 is made of stainless steel extended surface tube 21 and carbon steel elbow 22 (radius of curvature R=50mm) butt welding
Pipe row composition, generally S-shaped layout；Pipe group in-line arrangement, 80~90mm of transverse pitch, longitudinal pitch 100mm；Pipe row wears
The flue coaming plate 62 in frame 6 is crossed, with 62 joint outside weldings of flue coaming plate, is fixed, supported by flue coaming plate 62；Extended surface tube
And the flue coaming plate 62 in fin and frame 6 apart from for：Front and rear (arranging center with pipe) 40~45mm, left and right 23mm (with fin).
Stainless steel extended surface tube is as heating surface tube group.
Shell 4 is made of 1.2mm color steels, wraps insulating layer 3.
Insulating layer 3 uses alumina silicate fibre thermal insulation material, is surrounded on around the flue coaming plate 62 in frame 6, and front and rear portions are protected
