WASTE HEAT BOILER SERIES
Custom-designed waste heat boilers for steel, cement, glass, non-ferrous, petrochemical and other high-temperature processes. We convert your flue gas waste heat into useful steam or hot water to cut fuel consumption and CO₂ emissions.
Waste Heat Boiler Solutions for Process Industries
Focused answers to the key questions asked by plant managers, energy engineers and EPC contractors when planning a waste heat recovery boiler project.
Which process gases can your waste heat boilers handle?
We design waste heat boilers for a wide range of clean and dust-laden flue gases. Typical sources include:
- • Cement kiln, lime kiln and grate cooler exhaust
- • Sintering, coking, blast furnace and converter gas
- • Glass furnace, incinerator and thermal oxidizer exhaust
- • Gas turbine / engine exhaust and various process heaters
How is the boiler type and layout selected?
Boiler configuration is based on flue gas temperature, dust content, available space and required steam parameters. Our typical designs include:
- • Vertical / horizontal natural circulation boilers
- • Fire tube, water tube or hybrid arrangements
- • Modular sections for easier transport and installation
Final selection is confirmed after thermal calculation and mechanical design review by our engineering team.
How does the design improve efficiency and reliability?
Compared with conventional designs, our waste heat boilers focus on stable heat transfer and safe circulation:
- • Spiral finned tubes to enhance heat transfer and reduce footprint
- • Optimized gas flow and tube bundle arrangement to lower pressure drop
- • Proper drainage elbows and headers to avoid dead zones and water hammer
- • Flexible suspension or support structure with reliable expansion design
What information is required for a technical proposal?
The more complete the basic data, the faster we can prepare a suitable solution. Typically we need:
- • Process description and heat source (kiln, furnace, engine, etc.)
- • Flue gas temperature, flow rate, composition and dust load
- • Required steam / hot water pressure, temperature and flow
- • Site layout constraints and available installation space
- • Preferred design codes and any local regulations
What scope of supply can ORL Power provide?
Depending on project needs, we can supply from pressure-part only packages up to near-turnkey boiler islands:
- • Boiler pressure parts, casing, ducts and supports
- • Economizer, superheater, evaporator and steam drum
- • Valves, instruments and on-boiler piping
- • Steel structure and platforms around the boiler
Balance-of-plant items can be coordinated with your EPC contractor or supplied on request.
