The Effect of Adding Hydrogen to Natural Gas on Flue Gas Emissivity

Abstract

The aim of the article is to analyse the impact of adding hydrogen to natural gas. The main goal is to analyze the influence of the increase of hydrogen during the combustion of the gas-air mixture on the emissivity of flue gases in the combustion chamber, applying calculation methods from known relations that can be used in the creation of mathematical models. The created mathematical model simulates the increase in the amount of hydrogen in natural gas. The results are graphical representations of the courses of the selected parameters depending on the increase of the hydrogen content in the mixture. The increase of hydrogen in the fuel mixture confirms a significant effect on the emissivity of exhaust gases, especially from 60% hydrogen content. Moreover, with already 45% of hydrogen in the fuel mixture, the composition and volume of the exhaust gases also changes significantly.
