Harnessing Waste Heat for Efficient Power Generation: EPC Expertise in Gas Turbine Combined Cycle Projects‌

In today's industrial landscape, energy efficiency and sustainability are paramount. ZHM Huawu Steel has established itself as a trusted EPC (Engineering, Procurement, and Construction) contractor, delivering robust waste heat recovery (WHR) power solutions that transform gas turbine exhaust energy into reliable electricity. Drawing on proven expertise from multiple successfully executed projects, we design and implement WHR power plants that enhance operational efficiency and reduce environmental impact for industries worldwide.

Proven Capabilities in WHR Power Plant Design and Construction‌

Our experience spans comprehensive project execution—from initial design through commissioning—for plants like those developed for gold mining operations in Ghana. These projects involve recovering heat from gas turbines (including models such as TITAN 130 and MARS 100) to generate power. Utilizing double-pressure or single-pressure thermodynamic cycles, our systems achieve optimal energy recovery with minimal disruption to existing operations.

Core Technical Features of Our Solutions:‌

♦♦High-Efficiency HRSG Boilers:‌ Our horizontal, natural circulation waste heat boilers feature a three-stage design (including high-pressure superheaters, evaporators, economizers, low-pressure evaporators, and preheaters) to maximize heat transfer from exhaust gases. These boilers operate with minimal flue gas resistance (~2500 Pa) and high thermal efficiency, recovering up to 75% of available waste heat.

♦♦Robust Turbine and Generator Sets:‌ We integrate reliable condensing steam turbines (e.g., 22MW units operating at 3.43 MPa(a) and 435°C) paired with air-cooled generators. Our designs ensure stable operation across a 40–100% load range, supported by advanced DEH electro-hydraulic control systems for precise regulation.

♦♦Advanced Control and Automation:‌ A centralized DCS (Distributed Control System) provides seamless monitoring and control of all plant operations, including turbine-generator sets, boilers, pumps, and electrical equipment. This ensures safe, automated operation with capabilities for remote management and process optimization.

♦♦Comprehensive Supporting Systems:‌ Our projects include fully engineered auxiliary systems such as chemical water treatment (featuring reverse osmosis technology), circulating water cooling towers, electrical distribution (11kV MV switchgear, 415V LV panels), and fire protection—all designed to meet strict international standards.

♦♦Flexible and Reliable Integration:‌ Each boiler is equipped with inlet and bypass dampers, ensuring that the WHR system can be isolated without affecting the base gas turbine operation. This design guarantees continuous power availability for critical mining or industrial processes.

Key Project Highlights‌

In recent projects, we have delivered:

▶Modular power plants tailored to specific site conditions, with configurations ranging from single 22MW units to multiple-unit installations.
▶Seamless grid integration, incorporating fault current limiters and synchronization systems for safe parallel operation with existing electrical networks.
▶Low water consumption designs utilizing closed-loop cooling and efficient chemical treatment to minimize resource use.
▶Structural designs that account for local seismic and environmental factors, ensuring long-term durability.

Committed to Sustainable and Reliable Energy‌

At ZHM Metal Engineering, we focus on practical, technology-driven solutions that deliver tangible benefits. Our WHR power plants not only lower fuel consumption per unit of electricity but also reduce greenhouse gas emissions by utilizing otherwise wasted thermal energy. By partnering with us, clients gain a dependable EPC contractor capable of handling all project phases, ensuring on-time delivery, adherence to budget, and performance that meets or exceeds technical specifications.

Our expertise is grounded in real-world applications—every system we build is backed by detailed engineering, quality components, and a commitment to operational excellence. We invite industry partners seeking to enhance their energy efficiency and sustainability to explore how our waste heat recovery solutions can power their future.
