PT Journal AU Sikora, K TI Combustion of Natural Gas without the Presence of Nitrogen SO Acta Mechanica Slovaca PY 2024 BP 38 EP 42 VL 28 IS 4 DI 10.21496/ams.2024.021 DE Natural gas; chemical composition; stoichiometric equations; burners; flue gas; chimney. AB The following article deals with the consequences of burning natural gas without the presence of atmospheric nitrogen. It is primarily a change in the volumetric flow of flue gas in the exhaust system of the furnace. With the help of modified stoichiometric tables and the flow equation in the chimney, the difference in draft ratios of the furnace draft, when switching from conventional burners to oxygen burners, is demonstrated here on a specific industrial unit.
