18 black smoke filtration systems for large diesel generator sets have completed one year of stable operation overseas, demonstrating reliable emission control under demanding operating conditions.

Hebei Hanlan Environmental Technology Co., Ltd. supplied a complete exhaust black smoke filtration solution for an overseas diesel power generation project. Since commissioning, all 18 systems have maintained stable operation, with emission performance consistently meeting the applicable local environmental requirements.

Designed for Large Diesel Generator Sets
The systems were specifically designed for diesel generator sets with an 80-liter single-engine displacement.
Key equipment features include:
• 316 stainless steel housing for enhanced corrosion resistance
• Metal filter elements designed for high-temperature exhaust conditions
• Corrosion-resistant protection for critical components, including high-temperature valve actuators
• Third-party inspection and testing documentation
• Modular design for easier transportation and on-site installation

The filtration systems use Hanlan's dedicated diesel generator black smoke filter elements, featuring long service life, simple regeneration, low regeneration costs and no secondary pollution during normal operation.

Intelligent Monitoring for Reliable Operation
An integrated intelligent control system provides real-time backpressure monitoring, allowing the operating condition of the filtration system to be monitored continuously.
The system can also be interlocked with the diesel generator for automatic start and stop, helping maintain stable operation without requiring constant manual intervention.
The modular configuration offers several advantages for overseas projects:
• Compact footprint
• Easy transportation and assembly
• Convenient on-site installation
• Simple electrical connection

• Automatic operation through engine interlocking

Proven Performance Under Challenging Overseas Conditions
The project site experiences demanding environmental conditions, including significant day-to-night temperature variations, dust and high humidity.
After 12 months of continuous operation, the systems have experienced no major failures. Black smoke filtration performance remains stable, backpressure monitoring continues to operate normally, and the overall system remains in good operating condition.

This one-year operational milestone provides valuable field experience for Hanlan's overseas emission-control projects and demonstrates the reliability of its diesel generator exhaust treatment solutions in challenging environments.
