A Modular Structure of Radiant Section of Industrial Furnace

Abstract

The invention discloses a modular structure of a radiation section of an industrial furnace. The radiation section is divided into a plurality of polyhedral modules in the height direction of the radiation section. Each module is composed of at least four vertical faces; according to the difference of structures and demands, some modules can be provided with bottom surfaces or top surfaces, and some modules can be polyhedrons with corners. Each module is provided with a steel structure, refractory liner anchoring parts welded to a wall plate of the steel structure and a refractory liner; according to the difference of structures and demands, some modules can be provided with furnace accessories such as bottom combustors, side-wall bottom combustors, observation doors and operation doors. The modular structure of the radiation section of the industrial furnace has the advantages of being safe to manufacture, high in manufacturing speed, capable of reducing cost, stable in quality, free from weather effect, convenient to hoist on the spot and the like.

Description

technical field [0001] The invention relates to the field of petrochemical equipment, in particular to a modular structure type of the radiant section of an industrial furnace. Background technique [0002] Industrial furnaces (including various heating furnaces, hydrogen conversion furnaces and ethylene cracking furnaces, the same below) are one of the most important equipment in petrochemical plants, and the radiant section is the core part of industrial furnaces, and its structure is relatively large, Complex, high temperature in running state. The construction period of the radiation section directly affects the construction period of the entire furnace, and the construction quality of the radiation section also directly affects the performance indicators of the entire furnace. [0003] At present, most of the convection sections of industrial furnaces have realized modular design, modular workshop manufacturing and modular on-site hoisting. At present, due to the comp...

AI Technical Summary

Problems solved by technology

In the prior art, the on-site construction of the radiation section has the following disadvantages: 1. There are many high-altitude operations on site, and the risk and safety measures are relatively expensive

2. There are many shifts of large machines and tools used, and the construction cost is relatively high

3. Limited by site conditions and construction equipment, the construction quality is unstable

4. There are many cross operations on site, and the construction progress is slow

5. Since the site is open-air construction, the welding and lining construction is greatly affected by the weather, such as strong wind and heavy rain, which brings great inconvenience to the construction, and sometimes it is difficult to guarantee the construction quality
