The Heater model is a simple 0D model that adds or removes heat from a material stream.
import pyomo.environ as pe # Pyomo environment from idaes.core import FlowsheetBlock, StateBlock from idaes.generic_models.unit_models import Heater from idaes.generic_models.properties import iapws95
# Create an empty flowsheet and steam property parameter block. model = pe.ConcreteModel() model.fs = FlowsheetBlock(default={"dynamic": False}) model.fs.properties = iapws95.Iapws95ParameterBlock()
# Add a Heater model to the flowsheet. model.fs.heater = Heater(default={"property_package": model.fs.properties})
# Setup the heater model by fixing the inputs and heat duty model.fs.heater.inlet[:].enth_mol.fix(4000) model.fs.heater.inlet[:].flow_mol.fix(100) model.fs.heater.inlet[:].pressure.fix(101325) model.fs.heater.heat_duty[:].fix(100*20000)
# Initialize the model. model.fs.heater.initialize()
Aside from the inlet conditions, a heater model usually has one degree of freedom, which is the heat duty.
A heater model contains one ControlVolume0DBlock block.
The heat_duty variable is a reference to control_volume.heat.
A heater model contains no additional constraints beyond what are contained in a ControlVolume0DBlock model.
