Coal Pipe Balancing & Combustion

Coal Pipe/Fuel Balancing and Combustion Improvement Products: Optimize Performance & Efficiency

SAS Global Corporation develops advanced coal pipe balancing and fuel-distribution technologies for coal-fired electric power generation facilities.

Uneven pulverized coal distribution, improper primary airflow, and concentrated fuel streams can create significant differences in the air-to-fuel ratios delivered to individual burners. These conditions may contribute to inefficient combustion, elevated loss on ignition (LOI), increased emissions, furnace slagging, and accelerated burner component wear.

Correcting these challenges requires more than adjusting airflow alone. Effective fuel balancing must address how pulverized coal is distributed from the pulverizer, transported through the fuel piping, divided through riffle systems, and delivered to the burners.

A Comprehensive Approach to Coal Fuel Distribution

SAS Global offers four advanced technologies designed to address fuel-distribution problems at critical locations throughout the system:

Patented Conical Fuel Particulate Diffuser (CFPD)

Installed at the pulverizer or remote-classifier outlet, the Conical Fuel Particulate Diffuser is designed to disrupt concentrated coal streams and improve coal mass-flow distribution among multiple fuel pipes.

Patented Pre-Riffle Diffuser (PRD)

Installed immediately upstream of a riffle housing, the Pre-Riffle Diffuser conditions the incoming fuel stream to improve coal distribution between downstream branches.

Patented CV-Style Adjustable Orifice

The CV-Style Adjustable Orifice provides precise, repeatable adjustment of individual fuel-pipe resistance while the system is operating, supporting fine-tuning of primary airflow and overall fuel-system balance.

Patented In-Line Diffuser (ILD)

Installed near the burner, downstream of the final fuel-pipe elbow, the In-Line Diffuser is designed to reduce concentrated coal streams and promote more uniform fuel-air distribution entering the burner.

Key Benefits:

Improve Combustion: Enhance fuel burn efficiency for better energy output.
Balance Fuel Flows: Ensure uniform fuel distribution across all burners.
Improve Air/Fuel Ratios: Optimize the mixture for complete combustion.
Lower LOI (Loss on Ignition): Reduce unburned carbon in ash, indicating more efficient combustion.
Reduce Emissions: Lower NOx and CO emissions for environmental compliance.
Increase Burner Tip Life: Extend the operational lifespan of burner components.

By implementing SAS Global's patented technologies, you can achieve a more efficient, environmentally friendly, and cost-effective combustion process.
