Description

Technical Field

[0001] The present invention belongs to the technical field of coil-type water jacket heating furnace equipment, and specifically relates to a water jacket furnace with a quickly replaceable coil. Background Technology

[0002] Oilfield heating furnaces are commonly used equipment for crude oil gathering and transportation. Scaling and corrosion of the coils in the furnaces are a common problem. Scaling of the heating furnace coils reduces the pipe diameter and the flow cross-sectional area, resulting in poor heat exchange and coil blockage. At the same time, the internal pressure of the pipeline increases due to the reduction of the effective area in the pipe, which brings great safety hazards to production. Scaling of the coils will induce local corrosion, leading to coil leakage and even perforation, causing production safety accidents. Scaling of the heating furnace coils will also lead to problems such as reduced equipment thermal efficiency, increased energy consumption, and frequent replacement and maintenance of the coils, shortening the service life of the heating furnace and increasing maintenance costs and labor intensity.
