Notes on the emissions measurements
Stack particulate mass concentration is measured in milligrams per cubic metre (mg/m3). It describes the amount of dust in every cubic metre of air in the stack, at the point of measurement. Stack particulate mass flow rate is measured in grams per second (g/s). It is the product of the stack particulate mass concentration and the stack air flow and is an indicator of the amount of particulates exiting the stack.
Please note: To maintain accuracy, the monitors conduct a daily system calibration. This occurs at approximatley 12:15 on K5 and 12:45 on K6. The graph will exhibit a spike in the data that can reach up to 346mg/m3. These spikes are not a reflection of actual emissions.
