Utility model content
In order to solve prior art existing defects, the utility model provides the heat-conducting oil furnace that a kind of heating surface heat transfer coefficient is high, heating surface area increases.
In order to realize above object, the technical scheme that utility model is taked is: a kind of living beings both sides shape coil pipe heat-conducting oil furnace, comprise body of heater, the smoke-box in described body of heater has been arranged in juxtaposition two prescription shape coil pipes, and the wherein three side circles of every prescription shape coil pipe are attached at sidewall of the furnace body.
Further, wherein enclosing inside of described each prescription shape coil pipe is positioned in the middle of smoke-box, and has gap between the circle of the side of two prescription shape coil pipes.
Described every prescription shape coil pipe spirals be formed by stacking by with every three longitudinal close apposition of Guan Weiyi group.
The oil outlet end of described square coil pipe connects roof tube, and this roof tube is attached at body of heater roof.
Described smoke-box is also furnished with the snakelike tube bank be communicated with square coil pipe.
Described snakelike tube bank is the snakelike tube bank of double back journey, and the snakelike tube bank of described double back journey is connected between oil-feed header and intermediate header.
Compared with prior art, the utility model is owing to being set to both sides' shape coil pipe by heat-conducting oil pipes, by every prescription shape coil pipe wherein three sides circle be attached at sidewall of the furnace body and wherein side circle be arranged in flame kernel, more than 90% area of body of heater four sidewall is attached by two prescription shape coil pipes, the utilization rate in smoke-box space is the highest, add heating surface area, and two-sided being heated is enclosed in the side of flame kernel, improve heat transfer efficiency, simultaneously, because sidewall is close to by square coil pipe, reduce the heating temperature of sidewall, solve the resistant to elevated temperatures problem of sidewall.
In addition, due to stove furnace roof, portion is furnished with roof tube as heating surface, makes top furnace wall avoid high-temperature flue gas directly to wash away, and effectively prevents top furnace wall from coming off and produces the accident of urgent blowing out.

Detailed description of the invention
Living beings both sides shape coil pipe heat-conducting oil furnace, mainly comprises body of heater 2, chain furnace grate 12 and feeder 1.The overall accumbency of body of heater 2 is arranged.The bottom of body of heater 2 arranges chain furnace grate 12.Smoke-box 6 in body of heater 2 is divided into radiation area and convective region, and burner hearth 13 and top thereof are radiation area.
Convective region arranges that the snakelike tube bank 10,11 of winding type is as convection heating surface, and snakelike tube bank is two backhaul convection heat transfers.The body of heater roof lifting dividing plate 8 of convective region, convective region is separated into two parts by dividing plate 8, arranges the snakelike tube bank of the first backhaul 11 and the snakelike tube bank 12 of the second backhaul respectively.
Snakelike tube bank 10,11 is connected between oil-feed header 14 and intermediate header 15.The head section 14.1 of oil-feed header 14 is connected the snakelike tube bank 11 of the first backhaul with the head section of intermediate header 15, the interlude 14.2 of oil-feed header 14 is connected the snakelike tube bank 12 of the second backhaul with the rear of intermediate header 15, the rear 14.3 of oil-feed header 14 connects square coil pipe oiler.Head section 14.1 and the interlude 14.2 of oil-feed header 14 are spaced from each other (not connected), and interlude 14.2 and the rear 14.3 of oil-feed header 14 communicate.The head section of intermediate header 15 and rear communicate.
In burner hearth 13, (radiation area) arranges screw type square coil pipe 5, and square coil pipe 5 is divided into two groups, in radiation area about apportion.Square coil pipe 5 spirals be formed by stacking by with three longitudinal close apposition of Guan Weiyi group, and its center presents hollow structure.Square coil pipe 5 three outside circle attach sidewall of the furnace body, outside circle one side towards flame, belong to single side radiation heating surface; Square coil pipe 5 one inside enclose and be positioned in the middle of burner hearth, and have gap between the circle of the inner side of two prescription shape coil pipes, making inner side circle be submerged among flame, is double-side radiation heating surface.The top of square coil pipe 5 connects oil-feed roof tube 4, and oil-feed roof tube 4 other end access upper collecting chamber 7, the other end of upper collecting chamber 7 connects fuel-displaced roof tube 16, and fuel-displaced roof tube 16 other end accesses fuel-displaced header 3.Oil-feed roof tube 4 and fuel-displaced roof tube 16 attach body of heater roof side by side, and the heat radiation of Absorbable rod furnace flame, to protect body of heater roof.
The flow process of flue gas is: fuel falls into traveling-grate stoker 12 from feeder 1, traveling-grate stoker 12 burns, produce high-temperature flue gas in radiation of burner hearth district after the heat release of square coil pipe 5, enter convective region to flow through the snakelike tube bank 10 of the second backhaul snakelike tube bank 11, first backhaul and carry out convection heat transfer, be finally expelled to economizer by outlet flue 9.
The flow process of conduction oil is: the head section 14.1 first entering oil-feed header 14, flow through the snakelike tube bank 10 of the first backhaul, enter the head section of intermediate header 15, flow out from the rear of intermediate header 15, flow through the snakelike tube bank 11 of the second backhaul, enter the interlude 14.2 of oil-feed header 14, flow out from the rear 14.3 of oil-feed header 14, flow through two prescription shape coil pipes 5, one end that oil-feed roof tube 4 enters upper collecting chamber 7 is flowed through from square coil pipe 5, flow out from upper collecting chamber 7 other end again, flow through fuel-displaced roof tube 16 and enter fuel-displaced header 3.After high temperature heat conductive oil delivers to heating equipment heat release by fuel-displaced header, the recirculation of low temperature conduction oil enters heat-conducting oil furnace heat absorption.
