| Description
| - The environment suffers heavily from pollution caused by solid exhalations (particles smaller than 500 ?m). These are contained in the exhaust gasses of coal-fired power plants and heating stations, as well as being a by-product of building materials production, metallurgy, or waste incineration. Electrostatic precipitators count amongst the most effective systems used to eliminate solid exhalations. Their effectivity is affected by numerous factors, many of them related to physical and chemical properties of the separated particles. From the physical properties, not only resistivity is relevant, it is also important to know the size distribution and shapes of the dust particles. Knowing this distribution, it is possible to determine the charge of the particles and in turn choose a suitable type of precipitator. Information on the size distribution of solid particles and their shapes can be obtained by various - mostly optical - methods of measurement. This paper deals with a laboratory method of determining size distribution of solid particles using image analysis. Image Analysis has a wide range of possible uses (eg determining of distribution size, shape, edge detection) and many advantages including high assessment rate, full automation of calculations and very high level of control of the measurement process. The experimental part of this contribution deals with the sample preparation procedure, scanning of the picture, measurement and evaluation using NIS ELEMENTS AR 2.30 type Advanced Research (Laboratory Imaging) software. The measurement was performed on samples of dust from a solid waste incinerator and a heating station.
