Description
Technical field
The present invention relates to heating furnace technical field, more particularly to a kind of light boiler tube with uniform flow lid and has its heating
Stove.
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, boiler tube passed through in tubesheet holes 4,
Connection connection composition coil pipe is altered in the end of multiple boiler tubes 5 by elbow, and the main parts size such as coil pipe and header box forms heat exchange module,
Burner is installed in bottom after heat exchange module closed assembly, and chimney is installed at top, forms the body of heater of heating furnace.What is flowed through in boiler tube 5 is to need
The oil plant to be heated, see that the outside of Fig. 1 boiler tubes 5 flows through shown in arrow from the bottom up in burner hearth is high-temperature flue gas or hot blast, its
Heat is transmitted to oil plant or other media in boiler tube 5 by tube wall.
Traditional heating stove is because boiler tube to two still unsolved technical barriers, one side problem in furnace binding be present
The ability that outer surface obtains heat from flue gas on the whole can not meet boiler tube inner surface to oil product medium to heat energy power, for a long time with
Come, carry out enhanced heat exchange only by the bearing piece or bearing piece of tube skin, its DeGrain.Another aspect problem is the pipe of boiler tube
Wall is seriously uneven in the exchange capability of heat of circumference.Theory analysis and experiment show, during heat air-flow cross-flow tube bank, along flue gas gas
Flow direction, the windward side of boiler tube（It that is to say the front of boiler tube）With best heat transfer effect, and lee face（It that is to say boiler tube
Front）With worst heat transfer effect, the heat transfer effect of boiler tube both sides is in by-level.Three rows that stagger are taken out from Fig. 1
As shown in Fig. 2 due to Gravitative Loads, the center of boiler tube 5 is less than the center of tubesheet holes 4 for the boiler tubes 5 of row, in burner hearth from the bottom up
When sweep of gases shown in arrow is at boiler tube 5d front surface As, separates to be close to along dotted arrow from the both sides of boiler tube 5 and flow through, so
Depart from afterwards at the back side of boiler tube 5, continuation is up flowed at C and just merged, rather than is merged at the back surface B of boiler tube 5, so as in stove
A stagnant area 7, as shown in Fig. 2 medium square shades, horizontal stroke of the area's area equivalent to boiler tube 5 are formed between the back surface B and C of pipe 5
Sectional area, the tube wall in grid shaded region can not only play a part of due raising heat transfer effect, waste investment
Cost.The stagnant area similarly be present in the boiler tube layer of even front and rear face arrangement, the lee face of boiler tube.Boiler tube lee face changes
Why worst thermal effect is, and main cause is that the lee face of boiler tube has stagnant area, and air current flow is slow or does not flow, viscous flow cell
Increase with the increase of boiler tube diameter, hence it is evident that influence the efficiency of heating surface of heating furnace.In addition, after boiler tube long-term use, it is deposited on
Flue dust at bearing piece root on tube wall surface, especially on the tube wall at the boiler tube back side, this similarly have impact on the heat exchange effect of boiler tube
Fruit.
To sum up, the heat exchange efficiency of boiler tube turns into the key of energy conservation progress in heating furnace, improves boiler tube lee face
The heat exchange of stagnant area, it is both the main path for improving thermal efficiency of heating furnace, and makes full use of the power-economizing method of original resource, because
This gives to boiler tube more pays close attention to and carries out rational structural improvement, develops a kind of boiler tube of all-round side good effect of heat exchange,
There is very much engineering significance.
