Originální abstrakt

The study of particulate matter deposition on solid surfaces is an important subject for development of technologies for combustion of solid alternative fuels such as municipal solid waste (MSW). For this purpose, new experimental facility was build and available mathematical models of particulate matter fouling were examined. One of the two main parts of experimental facility is a deposition chamber, which became a subject to a subsequent simulations of initial stage of fouling process. We consider MSW as a testing fuel. A simple fouling model from group of critical velocity models was selected. Model parameter values were obtained from literature. Influence of variations of one of these parameters (reference diameter) on predicted deposition mass flux was studied. For considered size distribution the overall deposition mass flow shows only a little dependence on chosen reference diameter. Also simulation yielded the deposition chamber efficiency, showing ability to retain 15 % of overall particulate matter mass flux for considered size distribution.
