Determination of Dust Emission Amount at Nominal Reference Temperature Conditions

In industrial plants, flue gas analyzes need to be done in extreme conditions, for example high temperatures, high humidity or high dust in the flue gas. Emissions measurements are generally made in resource- and energy-intensive processes where large amounts of emissions such as carbon monoxide, carbon dioxide, nitrogen oxides or sulfur dioxide are produced. These emissions are subject to strict regulations to ensure compliance with set limit values and to optimize production processes and methods. These measurements are made by advanced laboratories with methods such as exhaust gas probe, sensor and automatic dilution.

The Method-5 method has been published by the Environmental Protection Agency (EPA) for the determination of dust emission amount under nominal reference temperature conditions. This method is applicable to the determination of particulate matter emissions from stationary sources. If the requirements of this method are followed, the quality of the data obtained from the air pollutant sampling methods increases.

Determination of dust emission amount under flue gas nominal reference temperature conditions is based on the following principle: particulate matter is taken from the flue in isokinetic conditions and the amount of particulate matter in the collected volume on the filter is determined.

The main standards considered in the determination of particulate matter are:

• TS ISO 9096 Fixed source emissions - Manual determination of mass concentration of particulate matter
• TS EN 13284-1 Fixed source emissions - Determination of mass concentration of dust in low range - Part 1: Manual gravimetric method
• EPA Method 5: Determination of particulate matter emissions from stationary sources in high humidity spots
• EPA Method 17: Determination of particulate matter emissions from stationary sources at locations free of high humidity
