Description
Technical field
Heating furnace technical field is the utility model is related to, more particularly to a kind of finned tube with uniform flow lid and there is its
Heating furnace.
Background technology
Heating furnace is the tap in petrochemical industry, generally include atmospheric pressure kiln, vacuum furnace, SECTION TUBE FOR HYDROGEN MANNU-FACTURING FURNACE, reformer, coking furnace,
Reburner and pyrolysis furnace etc..Acting on for tubular heater is by medium（Oil plant or gas）It is heated to the temperature needed for technique.
The four sides of the body of heater of heating furnace surrounds burner hearth by tall and big furnace wall, and furnace wall is by the profile steel frame such as I-steel upper berth welding steel
Plate, distribution welding bar for line, is molded into heat-insulated and high-abrasive material between bar for line on steel plate.Fig. 1 is composition heating furnace body
One piece of heat exchange module cross-sectional view, the support 2 installed on furnace wall 1 supports tube sheet 3, wing passed through on fin pore 4
Piece pipe（To increase heat exchange efficiency, finned tube is mostly finned tube 5）, connection connection composition is altered in the end of multiple finned tubes 5 by elbow
The main parts sizes such as coil pipe, coil pipe and header box form heat exchange module, and burner, top peace are installed in bottom after heat exchange module closed assembly
Chimney is filled, forms the body of heater of heating furnace.What is flowed through in finned tube 5 is the oil plant for needing to heat, and sees the outside of Fig. 1 finned tubes 5 in stove
What is flowed through from the bottom up shown in arrow in thorax is high-temperature flue gas or hot blast, and its heat is transmitted to the oil plant in finned tube 5 by tube wall
Or other media.
Traditional heating stove is because fin to two still unsolved technical barriers, one side problem in furnace binding be present
The ability that tube outer surface obtains heat from flue gas on the whole can not meet fin pipe internal surface to oil product medium to heat energy power, long
Since phase, enhanced heat exchange is carried out only by the fin or ailhead of fin pipe surface, its DeGrain.Another aspect problem is wing
The tube wall of piece pipe is seriously uneven in the exchange capability of heat of circumference.Theory analysis and experiment show, during heat air-flow cross-flow tube bank, edge
Flue gas stream direction, the windward side of finned tube has best heat transfer effect, and lee face has worst heat transfer effect, wing
The heat transfer effect of piece pipe both sides is in by-level.From Fig. 1 take out three staggered finned tubes 5 as shown in Fig. 2 due to
Gravitative Loads, the center of finned tube 5 are less than the center of tubesheet holes 4, and the sweep of gases in burner hearth from the bottom up shown in arrow arrives
When at the front surface A of finned tube 5, separate to be close to along dotted arrow from the both sides of finned tube 5 and flow through, then taken off at the back side of finned tube 5
From continuation is up flowed at C and just merged, rather than is merged at the back surface B of finned tube 5, so as between the back surface B of finned tube 5 and C
Form a stagnant area 7, as shown in Fig. 2 medium square shades, area's area equivalent to finned tube 5 cross-sectional area, it is cloudy in grid
Tube wall in the range of shadow can not only play a part of it is due raising heat transfer effect, and because occupy furnace cavity height and
Waste cost of investment.The stagnant area similarly be present in the fin tube layer of even front and rear face arrangement, the lee face of finned tube.
Why worst the heat transfer effect of finned tube lee face is, and main cause is that the lee face of finned tube has stagnant area, air current flow
Slowly or do not flow, viscous flow cell increases with the increase of fin pipe diameter, hence it is evident that influences the efficiency of heating surface of heating furnace.In addition,
After finned tube long-term use, the flue dust that is deposited at fin root on tube wall surface, especially on the tube wall of finned tube lee face,
This similarly have impact on the heat transfer effect of finned tube.
To sum up, the heat exchange efficiency of finned tube turns into the key of energy conservation progress in heating furnace, improves the finned tube back of the body
The heat exchange of wind face stagnant area, it is both the main path for improving thermal efficiency of heating furnace, and makes full use of the energy-saving square of original resource
Method, therefore finned tube is given and more pays close attention to and carries out rational structural improvement, develop a kind of all-round side good effect of heat exchange
Finned tube, have very much engineering significance.
