The problems such as high, seriously polluted of consuming energy be present in coal-burning boiler.Therefore, current reason is had become using combustion gas as industry and domestic fuel
The selection thought, gas fired-boiler will occupy more and more important position in our life.
The dry back structure that the front smoke box of existing boiler is surrounded by front tube sheet, preceding door closure with connecting plate, the boiler of pressure combustion
Temperature can reach more than 800 DEG C in front smoke box；Oil-burning gas-fired boilers all at present use flue structure, i.e. flue gas walks pipe
Interior, flue gas parallel baffled smoke pipe heat-transfer surface, surface film thermal conductance is relatively low；Existing central flame flame boiler turns the generally dry back of the body of smoke-box
Structure, during boiler operatiopn before plate temperature it is higher, not only radiation loss is larger, and the heat-resisting and sealing property to turning smoke-box will
Ask higher.
The content of the invention
In order to overcome the deficiencies in the prior art, clean energy resource, the transverse direction of energy-conserving and environment-protective are used the invention provides a kind of
Waterpipe type central flame flame boiler is washed away, it uses horizontal two return waterpipe type fuel-firing gas-firing quick fixation structure, and fuel can use natural
Gas, town gas, liquefied petroleum gas, heavy oil, light oil etc..
The technical solution adopted in the present invention is：A kind of transversal flow waterpipe type central flame flame boiler, critical piece include
Burner, housing, flue, turn smoke-box and box-type heat exchanger, it is characterised in that：Boiler shell is cuboid, and boiler smoke exchanges heat
The arrangement in face uses upper flue and the next box-type heat exchanger；Flue is waveform, is strile-backd centered on internal-combustion mode, stove
Courage front end is with turning smoke-box welding, rear end welding ellipsoidal head；The flue uses major diameter structure, and flue connects with turning smoke-box
And collectively form combustion space；The box-type heat exchanger is by four pieces of flat board vertical butt joints and is welded, and both ends of the surface are as flue gas
Inlet and outlet, its horizontal width is substantially equal with flue diameter, and its upper and lower panel is used as tube sheet, and multiple erect is arranged in box-type heat exchanger
Straight heat exchanging water pipe, heat exchanging water pipe are vertically fixed on tube sheet by welding, and heat exchanging water pipe is on tube sheet according to staggered triangular pitch
Arrangement, using smooth heat exchanging water pipe or outer fin heat exchanging water pipe；The gas approach of box-type heat exchanger is with turning smoke-box welding, cigarette
Gas outlet connection chimney or energy-saving appliance；Flue, turn smoke-box and box-type heat exchanger and be immersed in stove water, flue gas heat exchange face is complete wet
Back structure.
Compared with prior art, the beneficial effects of the invention are as follows：1. boiler uses horizontal two return waterpipe type structure, two times
Journey is box-type heat exchanger, is staggered in arrangement multiple vertical heat exchanging water pipes inside it, makes flue gas transversal flow heat exchanging water pipe, effectively carry
High flue gas and the heat exchange efficiency of heat exchanging water pipe；If heat exchanging water pipe uses external finned tube, flue gas and heat-exchanging water will further improve
The heat exchange efficiency of pipe；2. boiler uses central flame flame formula, the heat exchange efficiency of flue is effectively increased, reduces the face of follow-up heat-transfer surface
Product, it can reduce boiler volume, structure simplification, so as to reduce manufacturing cost；3. ellipsoidal head is welded in flue rear end, be advantageous to
Flue gas rotary in flue during central flame flame, avoid turning round dead angle, reduce gyroscopic moment loss；4. flue collectively forms with turning smoke-box
Combustion space, increase combustion space, improve heat exchange area；5. flue gas heat exchange face advantageously reduces stove using complete wet back structure
Body surface temperature, reduce radiation loss；6. box-type heat exchanger can be processed individually, manufacture is convenient, high-temperature flue gas can be avoided to exchange
Weld seam between hot-water line and tube sheet causes to damage, and is advantageous to improve the service life of boiler；7. boiler is using upper flue
The state of " under low upper height " is presented in arrangement, inner flue gas of the stove heat-transfer surface Temperature Distribution, and stove water uses " bottom in and top out " mode,
Temperature gradually rises during flowing up, and reaches the maximum effect of total heat transfer temperature difference.
