Boilers

Overview

We model heating plants based on their output:

• Hot Water Plants
• Steam Plants

Within a plant is its system of equipment:

• Boilers
• Heat exchangers
• Storage tanks

Heating plants share the following terminology with chilled water plants:

• primaryLoop: pipework within the plant
• secondaryLoop: pipework from the plant to the building

Hot Water Plants

The hotWaterPlant tag is used to model the plant and its system of equipment to generate hot water.

Plant level points:

• hot water leaving temp sensor
• hot water leaving temp sp
• hot water entering temp sensor
• hot water leaving flow sensor
• hot water leaving pressure sensor
• hot water entering flow sensor
• hot water entering pressure sensor
• hot water delta pressure sensor
• hot water delta flow sensor
• hot water delta temp sensor
• hot water bypass valve cmd
• hot water mixing valve cmd
• makeup water flow sensor
• outside air damper cmd
• flue temp sensor

Steam Plants

The steamPlant tag is used to model the plant and its system of equipment to generate steam.

• steam leaving temp sensor
• steam leaving temp sp
• steam leaving flow sensor
• steam leaving pressure sensor
• steam entering flow sensor
• steam entering pressure sensor
• steam delta pressure sensor
• steam delta flow sensor
• steam delta temp sensor
• steam bypass valve cmd
• steam mixing valve cmd
• steam header pressure sensor
• condensate entering temp sensor
• makeup water flow sensor
• outside air damper cmd
• flue temp sensor

Boilers

The boiler tag is used model boiler assets as an equip.

Equip level tags:

• equipRef must reference parent plant if associated with a plant
• hot water or steam
• oil or gas

Points associated with the boiler equip:

• run cmd
• run sensor
• enable cmd
• circ pump cmd
• circ pump sensor
• condensate pump cmd
• condensate pump sensor

Heat Exchangers

Heat exchangers are tagged with heatExchanger. Equip level tags:

• equipRef must reference parent hot water or steam plant

The points for a heat exchanger will be based on the fluids between the two loops. In general we use primaryLoop and secondaryLoop to quality the points.
