International Cement Review - Measuring Opacity and Particulate Matter

星期一, 三月 9, 2020

Read our latest article in International Cement Review where we discuss technologies available for the monitoring of smoke and dust emissions within the cement production process.

International Cement ReviewAmong the most obvious of hazardous air pollutants (HAPs), as it is readily visible by eye, is particulate matter (PM) - particles of smoke and dust. Small particlesbelow 2.5 μm in diameter are a special concern as they pose the greatest risk to health.

Some PM emissions can be categorised as fugitive and are generally subject to work practice controls. However, the main sources of emissions are the pyroprocesing unit (preheater, precalciner and kiln) and the clinker cooler, whose flue gases contain high concentrations of PM. If they are working correctly, modern abatement devices such as bag filters are highly efficient and can remove over 99.5 per cent of the PM in the flue gas. The purpose of emissions measurement is to demonstrate that abatement devices are functioning as intended that the residual PM emissions comply with the allowable emission limit values (ELVs).
