HTAC’s Water-Cooled Condenser (WCC) for Sembcorp 225MW CCPP Project

In 2016, HTAC successfully delivered a reliable and high-efficiency water-cooled condenser (WCC) for the 225MW Combined Cycle Power Plant (CCPP) operated by Sembcorp in Myingyan, Myanmar. This project, in collaboration with Baker Hughes GE (BHGE), showcases HTAC’s capability to design compact, high-performance condensers tailored to regional and operational requirements.

Client and Site Background

• End Client: Sembcorp

• Job Site: Myingyan, Myanmar

• Service Partner: BHGE

The Myingyan power plant plays a vital role in supporting Myanmar’s rapidly growing energy demand. Located in a developing market, the project required a reliable cooling solution to meet the region’s energy generation needs under challenging environmental and operational conditions.

Project Scope and HTAC’s Role

Project Requirements

The 225MW CCPP project required a water-cooled condenser that could meet the following demands:

1. Compact and Efficient Design: To fit within the power plant’s space constraints while maximizing cooling performance.

2. Flexible Connection Setup: Ensuring reliable and adaptable connections to the rest of the system.

3. Durability in Challenging Conditions: The condenser needed to operate reliably under Myanmar’s tropical climate.

4. Low Maintenance Requirements: A design that minimized downtime and maintenance frequency.

HTAC’s Solution

HTAC delivered a water-cooled condenser with an axial fan design, a total heat transfer area of 7,300m², and a flexible connection system. These features ensured that the condenser met the client’s operational and environmental demands while providing long-term reliability.

Key Features of the HTAC WCC

1. Compact Heat Transfer Area

• With a total heat transfer area of 7,300m², the WCC efficiently condensed steam from the turbine while maintaining a compact design.

• This feature enabled seamless integration into the plant's layout without compromising cooling performance.

2. Axial Fan Design

• The WCC was equipped with axial fans, which provided efficient and uniform airflow over the condenser tubes.

• This design significantly enhanced heat exchange while minimizing energy consumption.

3. Flexible Connection Setup

• The condenser was designed with flexible connection systems, ensuring smooth integration with the turbine and other components.

• This adaptability reduced installation complexity and improved overall operational reliability.

4. Durable and Low-Maintenance Materials

• Built with high-quality materials to withstand Myanmar’s high humidity and tropical conditions.

• The system’s robust construction minimized corrosion risks and reduced long-term maintenance costs.

5. Sustainability and Efficiency

• Optimized for low water consumption and minimal thermal discharge, the condenser supported the plant’s sustainability goals.

Results and Performance

Since commissioning in 2016, HTAC’s WCC has delivered outstanding results for the Myingyan 225MW CCPP:

1. Reliable Operation

• The condenser has consistently maintained optimal turbine backpressure, ensuring efficient power generation for Sembcorp.

• Its robust design has enabled uninterrupted operation despite challenging environmental conditions.

2. Efficient Cooling Performance

• The axial fan design and compact heat transfer area ensured rapid steam condensation and effective heat dissipation, maximizing plant efficiency.

3. Ease of Maintenance

• The durable construction and flexible connection system have minimized maintenance downtime, enhancing the plant’s overall productivity.

4. Environmental Compliance

• With its efficient water usage and reduced environmental footprint, the WCC aligned with local and international environmental standards.

Collaborating with BHGE

HTAC worked closely with Baker Hughes GE (BHGE) to ensure the condenser’s seamless integration with the plant’s combined cycle system. This partnership:

• Optimized Compatibility: The WCC was designed to meet BHGE’s turbine specifications and operational requirements.

• Streamlined Delivery: The system was delivered on time, ensuring the plant’s smooth commissioning in 2016.
