Consultation about temperature and pressure of stream

[zasddsgg]

Hello, could I ask you some questions about steam in BioSTEAM? Thanks for your help. Wish you a good day.

a) Why is the temperature and pressure of low pressure steam higher than that of high pressure steam?
The code is as follows:

from biorefineries import cellulosic
import biosteam as bst
from biosteam import settings
cs = cellulosic.Biorefinery('corn stover ethanol')
hps = settings.get_heating_agent('high_pressure_steam')
lps = settings.get_heating_agent('low_pressure_steam')
print(lps.T)
print(lps.P)
print(hps.T)
print(hps.P)

b) If the reactor temperature is 300 degrees, the existing high pressure steam can not meet the temperature requirements, what should be done? Is it set using hps = settings.get_heating_agent('high_pressure_steam'), hps.T=273.15+300，hps.P=12000000? Is this still the high-pressure steam produced by the boiler, and is the price of the high-pressure steam still set to 0?

c) As in (b), when the boiler is called using CHP_sys = create_coheat_and_power_system(), does the boiler automatically take into account the high pressure steam whose temperature and pressure is changed, and then calculate the amount of high pressure steam (whose temperature and pressure is changed) produced?
