GECPL, Specialist in environmental studies: # PERFORMANCE GUARANTEE TEST (PGT) Performance guarantee tests for environmental monitoring devices like ESP (Electrostatic Precipitators), Bag Filters, and FGD (Flue Gas Desulfurization) systems are critical to ensure that these systems meet the specified environmental emission standards and operate efficiently. These tests are usually performed after installation, during commissioning, and periodically during operation to ensure compliance with regulatory requirements. The purpose is to verify device performance meets design specifications, to ensure compliance with environmental regulations and to identify potential issues or areas for improvement # ESP: - Particulate matter (PM) collection efficiency, - Gas flow and pressure drop, - Electrical performance (e.g., voltage, current) # Bag Filter: - PM collection efficiency, - Gas flow and pressure drop, - Filter condition and integrity # FGD: - Sulfur dioxide (SO2) removal efficiency, - pH and chemical composition, - Gas flow and pressure drop Test Procedure: Pre-test preparations (e.g., device inspection, calibration), Performance testing (e.g., PM sampling, gas analysis), Data analysis and reporting and Comparison to guaranteed performance levels Benefits: Ensures environmental compliance, Verifies device performance and reliability, Identifies opportunities for optimization and improvement and Supports maintenance and troubleshooting efforts
