Reduction of NOx emissions using ceramic filter
Rubišar, Václav ; Niesner, Jakub (referee) ; Jedlička, Filip (advisor)
My bachelor's thesis deals with the problém of NOX reduction which is present in the flue gases. First is the description of all major types of NOX and are given their chemical properties. It is mentioned and their impact on human health and the mechanism of their formation. Furthermore, they presented all the major methods by which today achieves the reduction of nitrogen oxides from flue gases and waste gases, especially the method of selective catalytic reduction. That can be achieved in several ways - for example by using ceramic candles or fabric filters. Each of these methods is also listed with main advantages and disadvantages. Part of this work will become familiar with experimental filtration unit INTEQ II designed for selective catalytic reduction of NOX, a description of its function and a simple calculation of pressure losses in the ceramic candle.

Treatment of flue gas polluted by NOx II
Jedlička, Filip ; Jecha, David (referee) ; Dvořák, Radek (advisor)
My master’s thesis deals with the problems of NOx abatement that are included in flue gases. The accent is put on combined flue gases treatment throug ceramic candles, where the deposited catalyst enables NOx reduction throug the method of selective catalytic reduction. The main aim of my master’s thesis has been the design of experimental equipment for current removal of gas pollutants (dioxins, VOC and NOx) and fly-ash on catalitic ceramic candle. Design of experimental equipment consisted in the calculation of basic characteristics like pipe diameter, filtration chamber diameter, heater performance etc. During the design it was necessary to build pressure drop model that was split into head loss of ceramic candle and piping system. For the evaluation of experimentally measured data and for description of ongoing catalytic reaction in various operating conditions was made prediction model of catalytical filter. The last chapter deals with planned experimental testings.
