Measure Performance. Identify Inefficiencies. Optimize Combustion.

SAS Global Corporation provides comprehensive diagnostic testing, combustion analysis, and performance tuning services for coal-fired electric power generation facilities.

Achieving reliable boiler performance requires accurate control of coal fuel distribution, primary and secondary airflow, pulverized coal fineness, furnace temperatures, and combustion conditions.

When these operating parameters become unbalanced, power plants can experience reduced generation capacity, elevated NOx and CO emissions, increased loss on ignition (LOI), furnace slagging, higher fuel consumption, and accelerated equipment wear.

SAS Global's Performance Testing and Combustion Tuning Group combines advanced testing equipment, experienced field personnel, laboratory analysis, and engineering expertise to identify the underlying causes of these problems.

Comprehensive Diagnostic Testing Capabilities

ACFM Extractive Fuel Pipe Testing

Our Advanced Coal Flow Measurement (ACFM) system evaluates individual coal-pipe fuel flow, primary airflow, velocity, coal fineness, and air-to-coal ratios. These measurements help identify fuel-pipe imbalances, mill performance issues, and irregularities affecting coal delivery to the burners.

Real-Time Multi-Stream Combustion Analysis

Our Multi-Stream Combustion Analyzer provides simultaneous flue gas measurements at multiple sampling locations, allowing engineers to evaluate combustion conditions and monitor responses to approved burner and airflow adjustments.

High Velocity Thermocouple (HVT) Testing

HVT furnace traverses establish temperature profiles across selected boiler locations. When combined with appropriate flue gas sampling, these measurements help identify uneven furnace conditions, localized temperature differences, and potential combustion imbalances.

High-Volume Fly Ash Extraction & LOI Analysis

SAS Global uses extractive sampling to collect fly ash directly from the flue gas stream. Laboratory analysis of the collected samples helps evaluate loss on ignition and combustion completeness.

High-Temperature Boiler Camera Services

High-temperature visible-light and infrared camera equipment allows our specialists to inspect burner flames and furnace conditions during operation. Recorded observations can help identify flame instability, impingement, slagging, and other visible performance concerns.

Coal Fineness & Fly Ash Laboratory Analysis

SAS Global provides on-site and laboratory testing to evaluate pulverized coal particle-size distribution, fly ash LOI, and other selected fuel and combustion parameters.

From Diagnostic Measurements to Engineered Solutions

Our work begins by establishing the plant's actual operating conditions. Test results are reviewed to identify possible sources of fuel imbalance, improper airflow, inadequate fineness, abnormal furnace temperature profiles, and combustion inefficiencies.

SAS Global then develops an engineering assessment with findings and recommendations tailored to the facility's equipment and operating objectives.

Where included in the project scope, our team can support combustion tuning, operational adjustments, modernization recommendations, and post-improvement testing.

A Complete Approach to Coal-Fired Boiler Performance

SAS Global combines diagnostic testing with expertise in coal pulverizer modernization, fuel-pipe balancing technologies, burner components, engineering, fabrication, and field installation. This integrated approach helps power plants move beyond identifying performance problems toward implementing measurable, application-specific improvements.
