Description
Technical field
The manufacturing technology field of boiler is the utility model is related to, the fuel oil of finned tube built in specifically a kind of burner hearth,
Gas-steam boiler.
Background technology
China's coal-burned industrial boiler has nearly 500,000, and year expends 700,000,000 tons of coal, and it is big to account for national consumption of coal total amount.It is coal-fired
Industrial Boiler efficiency is low, pollutant emission level is high, automatization level is low, and immense pressure is caused to environment.As country saves
Energy emission reduction and haze administer the raising of demand, the further reinforcement of oil gas production of energy, and fuel-oil or fuel-gas boiler future can progressively replace
For the market of Small Coal-fired Boilers.
The content of the invention
The purpose of this utility model is to provide a kind of novel fuel, gas-steam boiler, to overcome present in prior art
The defects of.
The technical solution of the utility model is as follows：Upper drum and lower drum are longitudinally arranged, between upper drum and lower drum
Connecting tube is in D type shapes；Connecting tube between upper drum and lower drum constitutes radiation heating-surface and convection heating surface, its outermost
Two row's connecting tubes in face and middle row's convection tube are membrane wall structure, and the front side of boiler is panel and film type wall sealing, after
Side is film type wall sealing, and they together constitute burner hearth；Upper drum connects down-comer with the side of lower drum；Set in burner hearth afterbody
Fin heat exchange pipe is equipped with, is connected respectively with upper drum and lower drum；The rock wool heat-preservation that furnace wall is fixed by membrane wall and its outside
Layer composition, outermost is by color steel outer packing；It is provided with burner on front side of boiler, is energy-saving appliance on the outside of outlet flue, energy-saving appliance
Outside is chimney.
Further, the fin heat exchange pipe set in described burner hearth is 60.
Further, the rock wool heat-preservation thickness degree that described membrane wall and its outside are fixed is no less than 100mm.
Further, the down-comer that described upper drum connects with lower drum side is 2.
The utility model has the advantage of three row's membrane wall structures are used, reduce the air leakage coefficient of boiler, improve pot
The efficiency of furnace；Three row's membrane walls constitute the burner hearth of two backhauls simultaneously, add circulation time of the high-temperature flue gas in boiler, exchange heat
More fully, the loss of energy is reduced.Membrane wall and outside heat-insulation layer instead of heavy boiler setting, improve the peace of boiler operatiopn
Full property and portability, make the overall cost of boiler reduce, while reduce the expense of later maintenance.Burner hearth tail fin pipe is set
The heating surface for having increased considerably burner hearth afterbody is put, the exhaust gas temperature of boiler is reduced to less than 100 DEG C, has reached energy-saving and emission-reduction
Remarkable result, boiler is reduced bulk volume and weight, greatly reduce the floor space of boiler.

Embodiment：
Material is in the market public offering product used by the utility model.
As shown in figs. 1-7, the utility model upper drum and lower drum are longitudinally arranged, the connection between upper drum and lower drum
Pipe is in D type shapes；Connecting tube between upper drum and lower drum constitutes radiation heating-surface and convection heating surface, wherein, three rows
Connecting tube is membrane wall structure, and the front side of boiler is panel and film type wall sealing, and rear side is film type wall sealing, constitutes two backhauls
Burner hearth；Upper drum and lower drum one end are connected with two down-comers；The afterbody of burner hearth is provided with fin heat exchange pipe, respectively with it is upper
Drum is connected with lower drum.Furnace wall is made up of the rock wool heat-preservation layer in membrane wall and its outside, and outermost is by color steel outer packing；
Burner is provided with front side of boiler, is energy-saving appliance on the outside of outlet flue, is chimney on the outside of energy-saving appliance.
Described upper drum and lower drum one end is connected with down-comer, and quantity is 2.
The fin heat exchange pipe set in described burner hearth is 60.
The rock wool heat-preservation thickness degree that described membrane wall and its outside are fixed is no less than 100mm.
Combustion gas is burnt with air in burner during utility model works, and caused high-temperature flue gas exchanges heat via radiation
Radiation heating-surface is transferred heat to, the flue gas to exchange heat via radiation enters convection heating surface, and the flue gas into convection heating surface will
After heat transfer is to boiler tail fin heat exchange pipe, flue gas is pooled in energy-saving appliance, and after-heat is passed in energy-saving appliance
Convection bank, last flue gas are discharged by chimney.
Obviously, above-described embodiment of the present utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms.Here all embodiments can not be exhaustive.
It is every to belong to obvious changes or variations that the technical solution of the utility model is extended out still in of the present utility model
The row of protection domain.
