The tutorial shows steam power cycles using wood as fuel. The simulation of variants 1 and 2 takes the chemical composition of the fuel into account. As a result, stoichiometric combustion is calculated in the components, and supply and exhaust air flows are generated. Weather data have not been entered. The Interest rate and Tax rate are both set to 0.
Reference Case: Simple Steam Power Cycle
The reference case shows the process of electricity generation using a steam power cycle. The four state changes are represented by the corresponding components:
1. Adiabatic expansion,
2. Isobaric condensation,
3. Adiabatic pressure increase, and
4. Isobaric heat input.
Variant 1 With Intermediate Superheating
In the first variant, intermediate superheating is implemented at a medium pressure level. Heat from the steam generator’s exhaust gas is utilized for this purpose.
Variant 2 With District Heating
In the second variant, there is additionally a heat extraction system for a district heating network. For this, the condenser is replaced with a heat exchanger.
