Numerical Simulations of Flue Gas Flow in a First Stage Filter with Top Inlet -Modifications of the Inlet Chamber Inserts

摘要

This paper is focused on flue gas flow simulations in a first stage filter with top inlet that is used in a cogeneration power plant. CFD simulations were done with emphasize on the influence of inlet chamber on the flue gas distribution and filtering process. The flow has to be tumed at right direction in a quite small space. To achieve this change, distribution walls with flaps and duct inserts are used in the inlet chamber. The results showed that the main influence on the velocity distribution inside the filter have the inserts in the chamber.
