16.4 Heat Flow Function
Heat Flow Function set in Expansion Option 120 can be configured and used in different ways.
1. Steam Flow with default values
The steam flow is a calculated value based on:
• The commissioned Fuel Flow Metering on the MM, enabled in option 57.
• The standing losses are set as a fixed percentage in Expansion Option 121
• The total blowdown losses are set as a fixed percentage in Expansion Option 122
• The stack losses are set as a default fixed percentage value in the MM. If an EGA is enabled then
the stack losses are taken from the EGA rather than using a default value for the calculation.
