Boyu Industry has completed the delivery and on-site installation support of a customized    waste heat boiler system for a 2250 hot rolling furnace flue gas treatment upgrade project.    The equipment is designed to recover heat from high-temperature furnace exhaust gas and convert it into useful steam,    helping steel plants improve energy efficiency and support cleaner production.

Project Background: Waste Heat Recovery for Hot Rolling Furnace Exhaust Gas

In steel production, hot rolling furnaces and reheating furnace systems generate large volumes of high-temperature flue gas.    If this heat is discharged directly, a significant amount of thermal energy is wasted. At the same time, the high-temperature exhaust gas    may increase the load of downstream flue gas treatment systems.

A waste heat boiler is installed in the flue gas system to recover this thermal energy and generate steam.    The recovered steam can be used for plant utilities, process heating, or other energy-saving applications.    For steel plants upgrading their flue gas treatment systems, a waste heat boiler is an important solution for combining    energy recovery, emission control, and operating cost reduction.

This project was designed for a 2250 hot rolling furnace flue gas treatment upgrade. The waste heat boiler supplied by Boyu Industry    was manufactured as a complete system and delivered to the project site for installation.

Scope of Supply

Boyu Industry supplied one complete set of waste heat boiler equipment for the project. The supply scope covered the major boiler body,    structural components, pressure parts, platforms, auxiliary parts, instruments, and valves required for system operation.

The supplied equipment mainly included:

• Waste heat boiler main metal components
• Internal insulation and protective plates
• Steel frame and supporting structure
• Platforms, ladders, stairways, and access components
• Anchor bolts and installation-related components
• Boiler heating surface
• Steam drum and related accessories
• Primary instruments and primary valves
• Other supporting parts required for complete boiler operation

In addition to manufacturing and delivery, Boyu Industry also provided technical support for installation guidance, commissioning guidance,    performance assessment assistance, and final project acceptance support.

The following table summarizes the key project information and equipment supply scope.

On-Site Installation Support

Waste heat boiler projects in existing steel plants often involve complex site conditions. The equipment must be coordinated with the    existing building, steel structure, flue gas ducting, support platforms, lifting route, and downstream treatment system.

From the project site photo, the boiler module was lifted and positioned within the steel structure area. This type of installation requires    accurate prefabrication, reliable lifting points, proper module division, and close coordination between the manufacturer and the construction team.

Boyu Industry supported the project with installation guidance and technical communication to help the site team complete equipment positioning,    structural connection, and preparation for later commissioning.

Applications of Waste Heat Boilers in Steel Plants

Waste heat boilers are widely used in steel, metallurgy, coking, power, chemical, and industrial furnace systems.    In steel plants, they are especially suitable for recovering heat from high-temperature exhaust gas generated by heating furnaces,    reheating furnaces, hot rolling lines, and other thermal processes.

• Hot rolling furnace flue gas heat recovery
• Steel reheating furnace exhaust gas recovery
• Industrial furnace waste heat recovery
• Coking and metallurgical flue gas systems
• Energy-saving retrofit projects
• Steam generation from high-temperature exhaust gas
• Flue gas treatment system temperature control support
