The Effect of Inert Fuel Compounds on Flame Characteristics

To describe the effects of inert compounds in gaseous fuel, experiments on three different process burners (staged fuel burner, staged air and low-calorific burner) were carried out. The tested are commercially available, but they specially designed for experimental usage. Tests out semi-industrial burner testing facility to investigate influence gases flame characteristics, emissions, heat flux combustion chamber wall. Natural gas was used as a reference and, during all tests, thermal power 500 kW maintained. simulate alternative fuels with lower LHV, N2 CO2 diluents. hydrocarbon at certain conditions can NOx emissions (up 80%) increase 5%). Once incombustible present higher amount flowing through nozzles affects flow by increasing Reynolds number. This change pattern temperature field, it be both positive negative, depending actual conditions.
