Pulverized coal is conveyed to the burners through multiple pipes. The air and coal flow must be balanced to optimize burner performance and combustion. TOAN CAU provides a range of products and services to assist with balancing Primary Air and Coal Flow in coal pipes.

ADVANCED COAL FLOW MEASUREMENT - ACFM V2

The ACFM is a significant advancement over traditional testing systems, as it features fully computer-controlled vacuum adjustment and electronic data acquisition, eliminating the influence of operator error. The system has the capability to follow either the ISO 9931 or the ASME PTC 4.2 standards for pulverizer testing, providing accurate and reliable results.

100% Isokinetic Computer-Controlled Coal Pipe Extractive Testing

The Advanced Coal Flow Measurement System (ACFM) is engineered for high-accuracy air and fuel flow testing in coal pipes. Designed as a computer-controlled, PC-based isokinetic extraction system, ACFM provides real-time, precision diagnostics to optimize combustion efficiency and emissions control.

The ACFM™ measurements

How ACFM Ensures Accuracy

• Dual-Probe Technology – Utilizes a dirty air probe for airflow measurement and three specialized coal sampling probes for fuel analysis.
• Isokinetic Extraction Control – The system dynamically adjusts the extraction rate point-by-point to maintain 100% isokinetic conditions across the pipe velocity profile.
• Strict Accuracy Standards – Each pipe is rigorously tested, ensuring measurement precision within ±3% for air and ±6% for coal. If results exceed these tolerances, the test is automatically restarted for uncompromised accuracy.

With ACFM, TOAN CAU delivers the highest level of coal flow measurement precision, helping plants enhance combustion performance, reduce emissions, and optimize fuel efficiency.
