Abstract
A kind of reverse flue three backhaul combustion gas, oily hot-water boiler, it is characterized in that described hot-water boiler comprises: quarter bend head dummy combustion chamber (1), two return smoke discharging pipe (2), three backhaul smoke discharging pipes (3), front smoke chamber (4), rear smoke chamber (5), drum outside boiler (6) bottom is provided with water inlet pipe (7), and top is provided with outlet pipe (8), smoke exhaust pipe (9) and combustor interface (10). The present invention, owing to having changed the in-built structure of putting of water bath burner hearth, has given full play to the thermal efficiency of three backhaul smoke discharging pipes, and adopting the present invention to improve existing hot-water boiler will improve the thermal efficiency 10% left and right of boiler.
Description
Technical field
The present invention relates to the technology of flame smoke evacuation route trend in a kind of combustion gas, oily water bath body of heater, more specificallySaying, is combustion chamber and the cigarette line structure renovation technique of a kind of three return stroke wet back type gas, oily hot-water boiler.
Background technology
At present, conventional heating boiler, generally use is three backhaul combustion gas of wetting back-type, oily hot-water boiler, itIt is a kind of boiler of horizontal body of heater. This horizontal body of heater is column structure, and the combustion chamber in body of heater is also column typeStructure, the bottommost of its position in boiler thorax, is provided with two return smoke discharging pipe on top, combustion chamber, at two timesJourney smoke discharging pipe top is provided with three backhaul smoke discharging pipes, and front smoke chamber, the devices such as rear smoke chamber. Its operation principleBe: when after combustion chamber gas injection (oil) burning, the pyrotechnics of generation is along two return smoke discharging pipe, three backhaul smoke exhaust pipesRoad from bottom to top in a clockwise direction in stove motion finally from smoke evacuation chamber discharge, now, from boiler feed water mouthThe cold water entering is along with the temperature of the devices such as combustion chamber, two return smoke discharging pipe, three backhaul smoke discharging pipes raises alsoProgressively raise, the water temperature at the top in boiler also reaches with the temperature of three backhaul smoke discharging pipes the state of approaching, because ofThis, the high temperature of the three backhaul smoke discharging pipes in this time is inoperative to the rising of boiler water temperature, in vain lossHeat energy, thus cause boiler thermal output to reduce.
Summary of the invention
Not the object of the invention is to solve above-mentioned deficiency, a kind of total structure that neither affects boiler is provided, also notChange the mode of boiler Inlet and outlet water bottom in and top out, can save again the energy and make simple, easy for installation novelThree backhaul combustion gas of structure, oily hot-water boiler.
Invention is achieved through the following technical solutions: in horizontal boiler thorax, be provided with quarter bend head dummy combustion chamber, two go back tosJourney smoke discharging pipe, three backhaul smoke discharging pipes, front smoke chamber, rear smoke chamber and outside boiler boiler drum bottom be provided with into waterPipe, the top of boiler is provided with outlet pipe, is provided with smoke exhaust pipe is connected with rear smoke chamber at top, and combustion chamber is provided with burningMachine interface.
Their correlation is: quarter bend head dummy combustion chamber is located at horizontal middle part in boiler thorax, itOne end is connected with combustor interface, and combustion gas or fuel oil enter combustion chamber by combustor interface and burn, burningThe other end of chamber, namely bend part is connected with two return smoke discharging pipe. Establish the position of two return smoke discharging pipeOn the top of combustion chamber, its one end is connected with combustion chamber bend part, and the other end is connected with front smoke chamber; In burningBelow chamber, be provided with three backhaul smoke discharging pipes, its one end is connected with front smoke chamber, and the other end is connected with rear smoke chamber. TwoBackhaul smoke discharging pipe and three backhaul smoke discharging pipes are to be all welded to form side by side by some steel pipes are parallel, its quantityHow much be to decide according to the capacity of boiler, the boiler of common 1 ton, the about 0.8-1.2 of diameter in boiler thoraxRice, the quantity of two, three return duct can be at 30-36 root.
After starting working in combustion chamber, the pyrotechnics of combustion chamber enters from two return smoke discharging pipe, front smoke chamber with regard to easement pipeEntering three backhaul smoke discharging pipes finally arrives rear smoke chamber and discharges by smoke exhaust pipe. The direction of motion of whole pyrotechnics is oneAnticlockwise motion, therefore, we call reverse flue three backhauls this movement locus phenomenon, therebyForm the concept of " reverse flue three pass hot water boilers ".
The present invention is owing to having changed the in-built structure of putting of water bath burner hearth, by generally three backhaul smoke evacuations of application at presentPipeline is changed into the bottom of combustion chamber from the top of combustion chamber, namely three backhaul smoke discharging pipes are arranged on to boiler thoraxOn the position of the minimum water inlet of inner bottom part, this position is also low-temperature space in boiler. Three backhaul smoke discharging pipes are establishedObject is herein exactly in order to make the low water temperature district of three backhaul smoke discharging pipes in boiler thorax, and enters boilerCold water have a temperature difference, so just changed three backhaul smoke discharging pipes in the time of boiler thorax inner top position with at potThe hot water of burner hearth inner top does not have the problem of temperature difference waste heat energy, has given full play to the thermal effect of three backhaul smoke discharging pipesRate.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the invention will be further described:
Reverse flue three pass hot water boilers are also a kind of columniform horizontal boilers, in horizontal boiler thorax 13Be provided with quarter bend head dummy combustion chamber 1, two return smoke discharging pipe 2, three backhaul smoke discharging pipes 3, front smoke chamber 4, afterSmoke-box 5 and outside boiler drum 6 bottoms be provided with water inlet pipe 7, be provided with outlet pipe 8 above, in rear smoke chamber 5Top is provided with smoke exhaust pipe 9, and combustion chamber 1 is provided with the parts such as combustor interface 10 and combustor 11.
Their correlation is: quarter bend head dummy combustion chamber 1 is located at the centre of 13 lateral attitudes in boiler thoraxPosition, its front end is connected with combustor interface 10. Combustion gas or the fuel oil of quarter bend head dummy combustor 11 pass throughCombustor interface 10 enters quarter bend head dummy combustion chamber 1 and burns and arrive the other end of combustion chamber, namelyBend part 12, bend part 12 is connected with two return smoke discharging pipe 2. The position of two return smoke discharging pipe 2Be located at the top of quarter bend head dummy combustion chamber 1, its one end is connected with quarter bend head dummy combustion chamber bend part 12,The other end is connected with front smoke chamber 4; Below quarter bend head dummy combustion chamber 1, be provided with three backhaul smoke discharging pipes 3,Its one end is connected with front smoke chamber 3, and the other end is connected with rear smoke chamber 5. The connection of all parts recited above allForm by welding procedure.
Adopt the present invention to improve existing hot-water boiler and will improve the thermal efficiency 10% left and right of boiler.
