RotoTech Bangladesh Enhances Power Plant Efficiency with Nozzle Ring Specification Change at RotoTech Facility

Dhaka, Bangladesh — RotoTech Bangladesh Limited has successfully completed a groundbreaking project for Summit Kodda 300MW Power Plant Ltd, showcasing its ability to deliver cost-effective and performance-driven solutions. By upgrading TA20 nozzle rings to TA17 specifications in Wartsila W46V20 engines, RotoTech has achieved measurable improvements in engine efficiency, durability, and operational cost savings.

Enhancing Engine Performance

The TA20 nozzle rings in ABB TPL76-C33 turbochargers, previously used at Summit Kodda, were identified as limiting factors in engine performance. RotoTech’s transition to TA17 nozzle rings brought several direct benefits:

Improved Fuel Efficiency: Specific fuel consumption (SFC) was reduced by 2–3 grams per kWh, significantly lowering operating costs.

Lower Exhaust Temperatures: A reduction of 40–50°C indicated better thermal efficiency and combustion.

Enhanced Cylinder Valve Integrity: After 6,000 operating hours, cylinder valves with TA17 nozzle rings showed no signs of burning or wear, unlike their TA20 counterparts.

Broader Operational Benefits

The upgrade also yielded indirect advantages:

Extended Component Lifespan: Gas outlet and inlet casings, as well as turbine diffusers, experienced less wear and tear.

Thermal Stress Reduction: Minimized stress on the turbine shaft and nozzle rings enhanced system stability.

Optimized Maintenance: Reduced need for intermediate cleaning cut downtime and labor costs, improving plant operations.

RotoTech’s Refurbishment Expertise

In addition to installing newly supplied TA17 nozzle rings from Accelleron, RotoTech provided a cost-effective alternative by refurbishing existing TA20 nozzle rings to meet TA17 specifications. The refurbished nozzle rings underwent rigorous testing at Summit Kodda, demonstrating performance parity with newly manufactured rings. This innovative approach significantly reduced costs without compromising quality or reliability.

A Cost-Effective and Sustainable Solution

The project highlights the potential of refurbishment as a sustainable strategy for the energy sector. RotoTech’s refurbishment process not only reduced the environmental footprint by repurposing existing components but also delivered exceptional cost savings — a critical factor in today’s competitive power generation industry.

Conclusion

The successful transition from TA20 to TA17 nozzle rings at Summit Kodda underscores RotoTech Bangladesh Limited’s leadership in advanced engineering solutions. By enhancing engine efficiency, extending component lifespan, and reducing maintenance requirements, RotoTech continues to provide clients with innovative and economical alternatives to traditional replacement options.

This accomplishment reaffirms the company’s commitment to promoting sustainable and cost-effective solutions, making it a trusted partner for power plants across the region.
