Packaged Waste-Heat Thermal Oil Boiler

For sites with surplus high-temperature flue gas and a need for hot thermal oil. Adjusting the flue-gas flow through the heater stabilizes oil outlet temperature. All system equipment is integrated on one base.

Design and features

Integrated package

The heater, flue-gas inlet and circulation system are arranged together.

Circulation and oil-filling systems

Circulation comprises a thermal oil pump, filter, piping, valves, gaskets and fasteners; oil filling uses a filling pump and associated pipework. Pipes are grade 20 seamless steel to GB3087, with full-penetration argon-arc butt welds and 100% radiographic testing.

Oil/gas separation and storage

An oil/gas separator cleans the return oil. A storage tank at the system's lowest point holds oil during inspection or maintenance. Separator and tank plate materials are Q235-B or Q245R, with full-penetration butt welds and 10% radiographic testing.

Expansion tank and lighting

The expansion tank at the highest point stabilizes system pressure. It uses Q235-B or Q245R plate, full-penetration butt welds and 10% radiographic testing. Supports and ladders use welded Q235 tube, angle, channel or square sections. Explosion-proof lighting is provided at visual inspection points.
