Description

Technical Field

[0001] This utility model relates to the field of heating furnace technology, specifically to a fire tube heating furnace. Background Technology

[0002] Fire-tube heaters are widely used in natural gas stations. This is because natural gas pipelines use cryogenic compression transportation; once the natural gas arrives at the station, it must be heated from its low temperature to room temperature before it can be supplied to customers. Similarly, during crude oil extraction in oil fields, low temperatures cause the crude oil to become viscous. If the crude oil becomes viscous during pipeline transportation, it cannot be transported normally. Therefore, a heater is installed at intervals to heat the crude oil before it can be smoothly transported to the oilfield storage facilities.

[0003] However, existing fire-tube heating furnaces have certain structural design problems, with the operating room and ladders typically being separate. This dispersed layout complicates the connection lines and piping of the entire heating furnace system. During construction, the operating room and ladders require installation by different teams, with varying construction times, and extensive coordination work is needed during subsequent commissioning. This undoubtedly increases the construction difficulty and extends the construction period. Utility Model Content
