Modular manufacturing method for heating furnace and heating furnace manufactured through method

Abstract

The invention discloses a modular manufacturing method for a heating furnace. The method comprises the following steps that all modules and radiation fragments are prefabricated in a factory; foundation treatment is performed; the radiation fragments are lined; a furnace bottom is mounted; end walls on one sides are mounted; inner side walls, connecting profile steel among the inner side walls and inner side wall furnace tubes are mounted; outer side walls and outer side wall furnace tubes are mounted; end walls on the other sides are mounted; furnace top modules are mounted; radiation exhaust pipes are subjected to welding heat treatment; a radiation transfer convection gas flue is mounted; the furnace bottom and the radiation transfer convection gas flue are lined; the furnace is baked; convection modules are mounted; a stack is mounted; oil transfer lines are subjected to welding heat treatment; a convection module attached frame and a ladder platform are mounted; an overall hydrostatic test is performed; and outer surface treatment is performed, and identifications are marked. The modular manufacturing method for the heating furnace has the advantages that advantages of modular manufacturing are fully played, the manufacturing period is shortened, the manufacturing cost is lowered, and the manufacturing quality is improved.

Description

technical field

[0001] The invention relates to the technical field of heating furnace manufacturing, in particular to a modular manufacturing method of a heating furnace and a heating furnace manufactured by the method. Background technique

[0002] Some modern large-scale equipment has high parameters, many parts, large volume, and heavy weight. As the specialization and transportation conditions of cargo merchants continue to improve, major domestic refinery and chemical projects are undergoing modularization to ensure quality and cycle time. Compared with on-site manufacturing, modularization has the following advantages:

[0003] 1) Better working environment

[0004] The working conditions of the factory workshop are far better than the on-site conditions. It is less affected by weather and environmental factors, and is not limited by the three-dimensional space during on-site construction. Multiple modules can be manufactured at the same time. After modularization, t...
