AI Technical Summary

Technical Problem

The furnace box structure of the existing waste heat steam boiler is not strengthened enough, and long-term use of high temperatures leads to fatigue cracks, softening, and deformation of metal materials, and has a short service life. Moreover, the furnace box does not have flexible movement functions, which makes it inconvenient to install and transport.

Method used

A furnace box for waste heat steam boiler is designed, using four H-type supporting steel columns and two first-shaped supporting steel columns to strengthen the structural strength, and the sealing performance is improved by connecting to the paper-shaped connecting plate on the flue. The L-shaped support plate at the bottom of the H-type supporting steel column is connected to the threaded rod, driving the moving wheel to rotate to achieve flexible movement of the furnace box.

Benefits of technology

It enhances the structural strength of the furnace box, reduces deformation caused by high temperature use, and extends the service life; at the same time, it realizes the flexible movement of the furnace box, simplifies the installation and transportation process, and improves the convenience of use.

Abstract

The utility model provides a furnace box for a waste heat steam boiler, and belongs to the technical field of waste heat steam boilers. Comprising a waste heat recovery furnace body and a heating furnace body installed above the waste heat recovery furnace body, H-shaped supporting steel columns are fixed to the periphery of the waste heat recovery furnace body, two symmetrical first [-shaped supporting steel columns are fixed to the bottom of the waste heat recovery furnace body, a connecting-in flue is fixed to one side of the waste heat recovery furnace body, and a gas outlet flue is fixed to the other side of the waste heat recovery furnace body. A first concentric-square-shaped connecting piece is fixed to a smoke inlet of the access flue, a concentric-square-shaped clamping groove is formed in the surface of the first concentric-square-shaped connecting piece, and through cooperation of the four H-shaped supporting steel columns and the two first U-shaped supporting steel columns, the structural strength of the waste heat recovery furnace body can be enhanced, deformation caused by stress of the heated waste heat recovery furnace body is reduced, and the waste heat recovery furnace body can be heated conveniently. And meanwhile, the boiler box can be conveniently and flexibly moved, the installation position of the waste heat steam boiler is adjusted, and time and labor are saved.
