Determination of Dust Emission Amount: Temperature and Pressure Changes

Determination of Dust Emission Amount Considering Temperature and Pressure Changes

What is Emission?

Air pollutants emitted into the atmosphere from an enterprise as a result of processes such as decomposition, evaporation, synthesis and similar processes that occur with the combustion of fuels and the like, and the collection, separation and transportation of substances are called emissions. Flue gas emission measurements are more emission control. In this way, emissions are kept within the specified limits and legal regulations regarding emissions are complied with.

In addition, another reason for flue gas emission measurements is the control of combustion efficiency and boiler adjustment. In this way, the efficiency of the boilers is increased, fuel and money savings are achieved and emissions are reduced. Naturally, process control is also ensured with flue gas emission measurements. In this way, the quality of production processes is increased and the boilers used in the process are regularly adjusted.

Dust Emission and the Role of Temperature and Pressure Changes

In order to accurately calculate the amount of dust during emission measurements, temperature and pressure variations must be taken into account. This is because the volume of gases and particles varies depending on environmental conditions (especially temperature and pressure). The temperature and pressure of flue gases in industrial plants is an important factor in the calculation of dust emissions.

• Temperature: Temperature directly affects the density of gases. High temperatures cause gases to expand and therefore increase in volume. This can also affect the density of emissions. Therefore, it is necessary to correct the gas for temperature conditions during measurement.
• Pressure The pressure of the gas likewise affects the density of the gas. High pressure causes gases to be compressed and become more dense. Pressure changes must be taken into account in order to correctly calculate the amount of dust measured.

For these reasons, ignoring the effects of temperature and pressure changes during dust emission measurements can lead to incorrect results. Given these conditions, measured gas and dust emissions should be adapted to “standard conditions” (normalized conditions).

The main objectives of the Regulation on the Control of Air Pollution from Industrial Facilities published by the Ministry of Environment and Forestry are as follows:

• To control emissions in the form of soot, smoke, gas, dust, vapor and aerosols emitted into the atmosphere during the activities of industrial and energy production facilities
• Protecting people and the natural environment from hazards arising from air pollution
• Eliminating the negative effects of air pollution on the environment and ensuring that these effects do not occur

In this respect, it is important to determine the amount of dust emission by considering flue gas temperature and pressure changes.
