The Influence of the fuel used in the burner for heat transfer in process furnaces
 Jaworská, Petra ; Zejda, Vojtěch (referee) ; Skryja, Pavel (advisor)
This diploma thesis is about an influence of technical gases CO2 and N2, that are present in a fuel, over overall combustion process and a flue gas emissions. The first part of this thesis discussed issues like heat transfer, basic process combustion utilities, used technical gases in experimental part and finally description of observed pollutants. Second part of thesis describes the experiments themselves. Experiments were trying to find how selected parameters were influenced by adding 40 mN3/h or 80 mN3/h of inert gases to a flow of natural gas. Observed parameters were namely emission volumes, flame parameters and maximal heat duty. Experiments took place in horizontal water-cooled combustion chamber and were performed on two different types of burners. Evaluation of results confirmed clear connection of inert gases on temperature of flame; the biggest temperature drop was observed while inert gas CO2 was present in fuel. Lowering of temperature spikes also highly influenced presence of NOx in hot flue gas during all performed trials.
