Gelan engineers and manufactures high-performance Industrial Waste HeatRecovery Systems designed to
capture valuable thermal energy from flue gas,process streams, and incinerator exhaust.
In the energy-intensive petrochemical and refining sectors, thermal efficiency is critical. From Waste
Heat Boilers (WHB) to Heat Recovery Steam Generators (HRSG), Gelan's solutions are built to ASME
code standards. We help plants reduce fuel consumption and lower CO₂ emissions by converting
waste heat into process steam, electricity, or preheated feedstock.
Whether you need to retrofit an existing furnace or design a new WHRU for a greenfield project,
Gelan provides the thermal modeling and fabrication expertise to ensure maximum ROI.

| Comparison Item | Gelan Solution | Industry Challenge |
|---|---|---|
| Corrosion Resistance | ND Steel, Duplex, and Inconel combined with precise wall-temperature control to eliminate acid condensation | Sulfur- or acid-containing flue gas causes acid dew point corrosion and rapid failure of carbon steel equipment |
| Compact Design | Compact, modular design using custom H-fin and Spiral-fin tube bundles for retrofit applications | Limited space in existing plants restricts installation of conventional, bulky waste heat recovery systems |
| Anti-Fouling Performance | Optimized fin spacing with integrated soot blowers to ensure stable operation in fouling conditions | Particulates and soot in dirty exhaust gas quickly foul heat transfer surfaces, requiring frequent shutdowns |
| Energy Recovery Efficiency | Typical recovery of 10–20% waste heat, reducing burner fuel consumption and supporting emission targets | Rising fuel costs and emission limits increase pressure to improve energy utilization |
Recover heat from Ethylene Cracking Furnaces and Reformers. High-temperature exhaust is converted into high-pressure steam or used to preheat feed, achieving 10–15% operational energy savings.
Integrate WHRU systems with gas turbines. Our HRSG solutions recover exhaust energy to drive steam turbines, significantly boosting the plant's thermal cycle efficiency.
Reclaim thermal energy from Direct Thermalbr
Oxidizers (DTO) and industrial kilns. Recovered heat is recycled back into the process or used for plant utility heating.
We don't just fabricate; we engineer. Gelan utilizes HTRI and proprietary thermal modeling software to simulate heat loads, pressure drops, and flow dynamics. This ensures your system performs exactly as predicted under real-world conditions.
Waste heat streams can be chemically aggressive. We specialize in working with Carbon Steel, Stainless Steel (300 Series), Duplex, and Inconel to prevent dew-point corrosion and extend equipment life.
Our systems are designed for measurable results. By optimizing heat transfer areas and minimizing fouling factors, Gelan WHRUs typically deliver a return on investment within 2–4 years through fuel savings.
Trust is built on standards. Gelan is an ASME 'U' and 'S' Stamp holder. We also manufacture in compliance with PED (Europe), EAC (Russia), and other global pressure vessel codes.
From initial feasibility studies and FEED design to installation guidance and spare parts (finned tubes, bundles), we support your equipment throughout its entire operational lifecycle.
Depending on your process and exhaust temperature, Gelan systems can recover 10–20% of lost energy, significantly reducing fuel costs.
Yes. Our engineers assess your layout and process conditions to design seamless integration with minimal downtime.
Flue gas, furnace exhaust,reactor heat,and high-temperature processstreams-all customizable to your system's requirements.
Absolutely. Every system is engineered for your temperature, pressure, and media type. We also optimize thermal efficiency, equipment layout, and compliance with global standards.
We provide operational guidance, retrofits, module replacements, and periodic audits to ensure your system maintains maximum efficiency and lifespan.
