MGN 2800N HP 26BURNER PERFORMANCE CURVEBelow is the detailed operating data for the MGN 2800N HP.The graph contains the following: The certified burner performance envelope The gas head pressure curve The combustion air head pressure curve Gas train inlet pressure curvesThe total minimum gas supply pressure is obtained by summing the combustion chamber resistanceand combined burner head and line loss (shown as solid lines). A further 2.5 mbar should be addedto allow for manufacturing tolerances, etc.The gas and combustion air head pressure curves are supplied as a guide only and are not intendedto replace a full burner commissioning procedure using certified test equipment.The burner outputs are based on the gross calorific value of natural gas (38.56 MJ/m3).
