Dispersion studies for logistic problems
Dvořáček, Jan ; Šomplák, Radovan (referee) ; Pavlas, Martin (advisor)
Presented diploma thesis deals with the application of dispersion modelling of emissions from stationary sources of pollution as a potential tool which can be used for data preparation in reverse logistic models. In this case, the stationary source is represented by a waste-to-energy plant. The thesis consists of two main parts -- theoretical and computational. Firstly, emission sources and pollutants originating in thermal waste treatment are discussed. In the second chapter, legislation linked to the problem of air pollution is listed and the topics of current air quality in the Czech Republic and dispersion studies are outlined. Closing section of the theoretical part provides information about the principals of dispersion calculations and classification of dispersion models is given. In the computational part, the used dispersion software SYMOS'97 is introduced and the series of conducted calculations is presented. The calculations investigated the influence of plant capacity, dispersion conditions and terrain on the results. The input data of plant capacity and wind rose were indicated as key parameters in the calculation. The final evaluation revealed a good potential of the used dispersion model as a support tool in reverse logistic models.

Evaluation of air pollution in dependence on operation of centralized heating systems
Čejková, Eliška ; Matějíček, Luboš (advisor) ; Hůnová, Iva (referee)
1 ABSTRACT This bachelor work deals with some environmental aspects of disintegration of traditional centralized heating systems in the Czech Republic. This situation is shown on a particular case of centralized heating supply in a housing estate in town Kroměříž. This centralized heating system has been quickly disintegrating and it is close to its dissolution due to disconnection of customers who has been building their own local household gas boiler plants. The bachelor work calculates the consumption of natural gas for both ways of heating. It is calculated by using the amount of heat energy required for heating of all buildings, including domestic hot water and the average efficiency of these production methods. This work also calculates the amount of emissions NOx (nitrogen oxides) expressed as NO2 (nitrogen dioxid) which are producted by each type of heating. The amount of NO2 is calculated by using emission factor which is obtained from authorized measuring system. One part of this work also deals with nitrogen oxides in the atmosphere. Another important part of the bachelor work is about a basic dispersion analysis (study) - dispersion model of pollutant (nitrogen oxides) around the source/sources. One chapter compares the environmental impacts of central and local way of heating from the viewpoint...
