Application Background

In 2019, we supplied condensate iron removal filtration equipment for the 2×1050 MW Java 7 coal-fired power plant project in Indonesia.

Located in Banten Province on the island of Java, the project is a large-scale ultra-supercritical coal-fired power project with a total installed capacity of 2×1050 MW. The project was developed to strengthen electricity supply in Java and Bali, with an expected annual power generation of approximately 15 billion kWh. 

Our filtration equipment was applied to the condensate system to remove iron-containing impurities and corrosion products, helping maintain condensate quality and improve heat-transfer performance within the power generation cycle.

The Problem

During the operation of a large coal-fired power unit, corrosion products and iron-containing particulate impurities can enter the condensate system.

These contaminants may accumulate on heat-transfer surfaces and affect the performance of the condensate and steam-water cycle, potentially resulting in:

• Reduced heat-transfer efficiency
• Increased thermal losses and operating energy consumption
• Higher impurity loading in downstream water-treatment processes
• Increased maintenance requirements
• Reduced overall operating efficiency of the generating unit

For a 2×1050 MW power plant, even relatively small improvements in thermal efficiency can translate into significant fuel and environmental benefits over long-term operation.

The Solution

We designed and supplied a condensate iron removal filtration system for the Java 7 power plant.

The system was integrated into the condensate treatment process to continuously capture iron-containing particulate contaminants and corrosion products from the condensate stream.

Key solution features:

• Customized filtration equipment for the 2×1050 MW generating units
• Effective removal of iron-containing impurities from condensate
• Protection of heat-transfer surfaces
• Improved condensate water quality
• Reduced impurity circulation within the steam-water cycle
• Support for improved heat-transfer performance and operating efficiency

By controlling iron-related impurities in the condensate system, the filtration solution helped maintain cleaner heat-transfer surfaces and supported efficient, stable operation of the generating units.

Project Impact

According to the project’s reported operational assessment, the filtration solution contributed to significant resource and environmental benefits compared with conventional generating units.

The reported water-saving figure is equivalent to the annual water consumption of approximately 5,000 local residents.

The Java 7 project itself was designed as a high-efficiency USC power plant, and public project information reports an expected annual generation of around 15 billion kWh.
