Abstract
The utility model relates to a corrugated furnace wall high-efficient radiation chamber of a tube type heating furnace, which consists of a furnace body, a furnace wall, furnace tubes and a burner, wherein longitudinal arc-shaped grooves and ledges are alternately arranged and transversely connected on the inner surface of the furnace wall, and the vertical furnace tubes are arranged on the same section axis in the groove. The section circle of the vertical furnace tube and the cambered surface of the groove have the same circle center. The corrugated furnace wall high-efficient radiation chamber of the tube type heating furnace has reasonable design and simple structure, the furnace wall of the radiation chamber is changed to present a cylindrical surface structure having the same circle center with a single furnace tube from a flat surface structure on the premise that the overall structure of the furnace body is not changed, the reflection efficiency of the furnace wall is increased, the temperature difference between the radiation surface of the furnace tube and the reflection surface is reduced, the average heat intensity of the furnace tubes is improved, the service life of the furnace tubes is prolonged, and simultaneously the radiation heat intensity of the vertical furnace tube is increased by about more than 20 percent, so the overall heat load of the heating furnace can be increased by more than 10 percent on the premise that the overall structure size of the heating furnace is not changed, and the comprehensive efficiency of the heating furnace is increased.
Description
Technical field
The utility model belongs to the heating furnace radiation chamber, particularly relates to a kind of tubular heater watt rib furnace wall high efficient radiation chamber.
Background technology
In the petrochemical industry process, heating furnace is the most basic, imperative equipment, it simultaneously also is the key equipment that petrochemical industry production capacity size is played decisive factor, the thermic load size of heating furnace is the working ability of decision petrochemical equipment directly, therefore, under the situation of equal contour structures, it is particularly important that the thermic load of raising heating furnace shows.According to present science and technology development present situation, closely bound up with the thermic load of petrochemical industry heating furnace is that the heat exchange area of heating furnace radiation chamber boiler tube is (because of the surface heat intensity of boiler tube is limited to certain limit, can not infinitely increase), the evenly heat intensity that therefore improves heating furnace radiation chamber boiler tube is to improve the effective way of heating furnace thermic load.And existing heating furnace radiation chamber strengthens the temperature difference of boiler tube radiating surface and reflecting surface because the furnace wall design is unreasonable, and shortened the service life of boiler tube, influences the heat exchange efficiency of boiler tube.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of tubular heater watt rib furnace wall high efficient radiation chamber is provided.
Tubular heater of the present utility model watt rib furnace wall high efficient radiation chamber is to be made of body of heater, furnace wall, boiler tube and burner.The inner surface of described furnace wall replaces the horizontal row that run in for arc groove and fin longitudinally, and vertical furnace tube places on the same cross-sectional axis of groove.
As further improvement of the utility model, the cross section of vertical furnace tube circle is a concentric with the cambered surface of groove.
Tubular heater of the present utility model watt rib furnace wall high efficient radiation chamber, reasonable in design, simple in structure, be under the constant prerequisite of body of heater general structure, change the furnace wall of radiation chamber into the cylindrical structure concentric by the plane to single boiler tube, improve the furnace wall reflection efficiency, reduce the temperature difference of boiler tube radiating surface and reflecting surface, improve boiler tube evenly heat intensity, prolong the service life of boiler tube, it is about more than 20% simultaneously can to improve vertical boiler tube radiant heat density, thereby can reach under the prerequisite of heating furnace general structure size constancy, heating furnace overall thermal load can improve about more than 10%, improves the overall efficiency of heating furnace.
Description of drawings
Fig. 1 is the longitudinal sectional drawing of the utility model tubular heater watt rib furnace wall high efficient radiation chamber.
Fig. 2 is that the utility model tubular heater watt rib furnace wall high efficient radiation chamber A-A is to cross sectional plan view.
The specific embodiment
Tubular heater of the present utility model watt rib furnace wall high efficient radiation chamber, be to constitute by body of heater 1, furnace wall 2, boiler tube 3 and burner 4, replace horizontal run in row for arc groove 5 longitudinally with fin 6 at the inner surface of furnace wall 2, vertical furnace tube 3 places on the same cross-sectional axis of groove 5.Wherein, the cross section of vertical furnace tube 3 circle is a concentric with the cambered surface of groove 5.
Claims (2)
1, tubular heater watt rib furnace wall high efficient radiation chamber, be to constitute by body of heater (1), furnace wall (2), boiler tube (3) and burner (4), the inner surface that it is characterized in that furnace wall (2) replaces the horizontal row that run in for arc groove (5) longitudinally with fin (6), and vertical furnace tube (3) places on the same cross-sectional axis of groove (5).
2, tubular heater as claimed in claim 1 watt rib furnace wall high efficient radiation chamber is characterized in that the cross section circle of vertical furnace tube (3) and the cambered surface of groove (5) are concentric.
