Abstract

The invention discloses an ordinary pressure water jacket furnace of an acidic gas field wellhead. The ordinary pressure water jacket furnace of the acidic gas field wellhead comprises a horizontal type shell body, a fire cylinder is arranged at the lower portion of a shell body cavity, the fire cylinder is in flanged connection with one end of the shell body, a burner and a chimney are arranged at the outlet position of the fire cylinder, a coiled tube device feeding with natural gases is arranged at the upper portion of the shell body cavity, an expansion tank is arranged at the outer portion of the shell body, the expansion tank is communicated with the shell body cavity, heat-transfer mediums are arranged in the shell body cavity, and the coiled tube device is in flanged connection with the other end of the shell body. The coiled tube device comprises a primary coiled tube and a secondary coiled tube, a throttle valve is arranged between the primary coiled tube and the secondary coiled tube, and the pressure grade and the tube diameter of the primary coiled tube and the secondary coiled tube are not the same. The ordinary pressure water jacket furnace of the acidic gas field wellhead can heat the natural gases effectively. Besides, the ordinary pressure water jacket furnace of the acidic gas field wellhead is convenient to transport, mount and maintain.

Description

technical field [0001] The invention relates to the field of heating furnaces in oil and gas fields, in particular to wellhead atmospheric water jacket furnaces for acid gas fields. Background technique [0002] The existing water jacket heating furnace is usually located between the wellhead and the gathering pipeline in the oil and gas gathering and transportation system, and its function is to increase the temperature of crude oil or natural gas for subsequent processing and transportation. The traditional gas field wellhead water jacket furnace has only one-stage heat exchange coil, which can only heat the natural gas to a certain temperature, but cannot adjust its pressure. Moreover, the furnace body is sealed and welded as a whole, which belongs to the pressure-bearing furnace. When the heat exchange coil or torch breaks down, it will take a lot of work to repair or replace it, and it will affect the strength and service life of the heating furnace. Contents of the i...
