Compound gas superconductive heater

Abstract

The invention provides a combined type fuel gas superconducting heater, consisting of a heater and a flue gas after-heat exchanger, wherein, one end of the heater is provided with an inflamer, a burning chamber which is communicated with the inflamer is positioned inside the heater and goes through the bottom of the heater, the burning chamber is communicated with one end of a flue pipe, the other end of the flue pipe is connected with a flue gas splitter chamber of the flue gas after-heat exchanger, the inside section of the flue gas splitter chamber is provided with a perforated plate of a flue pipe branch, the perforated plate is connected with a plurality of flue pipe branches, the other end of the flue pipe branch is communicated with a chimney; an oil inlet is positioned on the upper part of a crust of the flue gas after-heat exchanger, a heating pipe goes through the flue gas-after heat exchanger and then enters into one end of the heater, the heating pipe goes through the inside part of the heater, an oil outlet is positioned on the other end of the heater. The invention has the advantages of high operating factor of flue gas and after heat, raised thermal efficiency of fuel gas, no need of aqueous medium, prolonged service life, simple structure, safe and convenient construction and low cost.

Description

Technical field: [0001] The invention relates to a medium heating device in the field of petrochemical industry, in particular to a compound gas superconducting heater. Background technique: [0002] Crude oil transportation in oilfields requires heating, and the heating methods currently used mainly include the following: ①Water jacket furnace heating method, ②Superconducting furnace heating method, ③Electric heating method. Since the heat conduction medium of the jacketed water furnace heating method is water, the corrosion of water on the heater is relatively large, which affects the service life of the heater, and it is difficult to add water to remote wells. In the device structure, the furnace hall and the flue gas channel are in the same room, so the temperature of the flue gas cannot be lowered, and the energy saving effect is not good; the electric heating method consumes a lot of energy and has a low safety factor, so it is generally not commonly used.
