Abstract
The utility model discloses a novel metal furnace tube of a heating furnace, which mainly consists of a tube body, and is characterized in that the tube body is provided with a torsion angle. The novel metal furnace tube is reasonable in structure and skillful in conception, can change flow states of fluid in the tube, damages flow regularity, changes flow rate distribution in the tube, increases collision probability among fluid molecules, improves heat transfer efficiency of the heating furnace tube, prolongs coking time of products in the tube, reduces production cost and further increases product output. Single furnace tubes which are manufactured in a factory can be assembled into an integrated furnace tube to form a whole set or to be modular, and then the furnace tube can be directly mounted in the heating furnace on the site for production. The novel metal furnace tube of a heating furnace has extremely high social benefit.
Description
Technical field
The utility model relates to novel boiler tube manufacturing of a kind of heating furnace metal and package technique, belongs to petrochemical industry, chemical industry, petroleum industry furnace apparatus technical field.
Background technology
In furnace apparatus, the furnace tubing ubiquity at present: 1. boiler tube is short service life.2. heat transfer efficiency is low.3. the easy defective such as coking in boiler tube of product has greatly hindered product yield ground and has improved.
Summary of the invention
The purpose of this utility model is, provides a kind of and can eliminate above-mentioned defective, improves the heating furnace tube heat transfer efficiency, prolongs the time of product coking, reduces the novel boiler tube of heating furnace metal of operating cost.
For achieving the above object, the utility model adopts following technical scheme: the novel boiler tube of a kind of heating furnace metal, its characteristics are that boiler tube has torsion angle.It can be static casting, also can be rolling, or centrifugal casting.
Owing to adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is rational in infrastructure, be skillfully constructed, it can change the flow regime of tube fluid, has destroyed the regularity that flows, changed the distribution of velocity in pipes, increase the collision probability between fluid molecule, improved the heat transfer efficiency of furnace tubing, prolonged the time of product coking in pipe, reduced the production run cost, the output of product is improved.After single boiler tube is finished in manufactory, also can be assembled into whole boiler tube, complete or one-tenth modularization directly is installed at the scene in the heating furnace and uses for producing, and this technology has great social benefit.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a cross-sectional view of the present utility model;
Fig. 3 is the structural representation after many assembly units of the utility model.
The specific embodiment
Referring to accompanying drawing, the configuration of this metal boiler tube is a body, and has torsion angle.It can be static casting, also can be rolling, or centrifugal casting.Its material can be carbon steel, chrome-molybdenum steel, stainless, also can be high-class stainless steel 25Cr-20Ni material, 25Cr-35Ni material, 35Cr-45Ni material, 20Cr-32Ni material bodies series.The torsion angle of boiler tube can be 0-10 degree or other number of degrees.Boiler tube is a modification, can be bull circle, ellipse, waveform, petal, perhaps other distortion.His diameter is from Dg15-Dg300, and his single-unit length L can be from 100 millimeters-5000 millimeters.It also can be assembled into one whole novel boiler tube by the distortion boiler tube of two or several single-units, several whole long metal boiler tubes can or built the job site in manufactory, form one or more distortion boiler tube groups by short straight tube, elbow or other pipes, be placed on heating furnace integral device of formation in the heating furnace, use for manufacturer.
