Heating medium furnace for long-distance-delivery crude oil pipeline

Abstract

The invention discloses a heating medium furnace for a long-distance-delivery crude oil pipeline for crude oil delivery. The heating medium furnace for the long-distance-delivery crude oil pipeline mainly comprises a radiation chamber, a burner, a transition section, a convection chamber, a convection chamber soot blowing system and a chimney, wherein multiple horizontal radiation furnace tubes are erected in the radiation chamber, and the two ends of the radiation furnace tubes are communicated through elbows, so that it is guaranteed that a one-way passage is formed for each radiation furnace tube; multiple horizontal convection furnace tubes are erected in the convection chamber, the two ends of the convection furnace tubes are communicated through elbows, so that it is guaranteed that a one-way passage is formed for each convection furnace tube; the convection furnace tubes and the radiation furnace tubes are communicated through oil transferring lines. By the adoption of the heating medium furnace for the long-distance-delivery crude oil pipeline, various problems of a direct heating type heating furnace are solved, the safety performance and the operating heat efficiency are improved, and operating cost is reduced; due to the fact that finned tubes and a single-tube-pass structure are adopted, the size of equipment is reduced, and the phenomenon that a medium flows in a deflected direction is avoided; the medium atomizing burner is adopted, the fuel atomizing effect is improved, the combustion performance is improved, dust emission is reduced, and operating heat efficiency is improved.

Description

technical field [0001] The invention relates to a heating furnace, in particular to a heat medium furnace for a long-distance crude oil pipeline used for crude oil transportation. Background technique [0002] When long-distance crude oil pipelines are in operation in winter, affected by the temperature, the temperature of crude oil decreases, the viscosity increases, and the difficulty of crude oil transportation and operating costs also increase significantly. In order to overcome the influence of temperature on crude oil transportation, heating furnaces are installed at each oil transportation station to heat crude oil. my country's crude oil has a high freezing point, and a large number of heating furnaces are used. Although the furnace types used in various long-distance pipelines are not exactly the same, most of them are direct heating furnaces. Countries around the world also use a large number of heating furnaces. Russia mainly uses direct heating furnaces, and th...

Problems solved by technology

During the nearly 20 years of use of the direct heating furnace, there have been many problems such as cold corrosion of the radiation furnace tube and the convection furnace tube, dust accumulation in the convection chamber, peeling off of the insulation layer in the convection chamber and the radiation chamber, and water seepage in the elbow box of the convection chamber. The safe operation of the heating furnace brings hidden dangers, which also makes the maintenance of the heating furnace more frequent and increases the workload of maintenance personnel
