Boilers: Industrial Point Sources

1. Boilers or Industrial Stacks are always linked to an industrial plant, and can have (optional) time-series of emission data;
2. Small Stacks, that are "singular", have no plant grouping but may have an optional contact address of a plant, and have a single, average emission value for each pollutant substance.

Point sources or stacks/boilers can optionally be grouped into

• plants representing industrial installation that also hold administrative data such as street address, contact person, ISIC classification, start of operations, etc.

• Name, short description, owner, creation and last modification date;
• Georeference: symbolic and (type specific, reference point at the base of the stack);
• Hypertext description (with import function);
• Type specific attributes (Descriptors):
  • Stack height, diameter
  • Industry classification (ISIC)
  • Boiler type, power rating, primary fuel, average fuel consumption.
  • Other optional attributes (open list of Descriptor-Value pairs that can be configured with the KB editor and the OBJECT TEMPLATEs). Examples are operating hours, start time and stop time of operations.
• Source specific temporal scaling factors (for month, day, hour)
• a TABLE of substance specific average (default) emission values;
• optional one or more Substance (or parameter) specific temporal scaling factors;
• optional time series of Emission values (for boilers and stacks), includes flue gas temperature and velocity), and optinal related parameters such as flue gas volume or fuel consumption, with a generic time series import function.
