For a thermal deaerator, the goal is to heat the water to its saturation temperature, which is the temperature at which the water will start to boil at the given pressure. This process is crucial for effective deaeration, as the solubility of gases in water decreases as the temperature increases.
To avoid water hammer, the electric valve controlling the steam flow should be modulated to ensure a gradual and controlled increase in temperature.
A simplified formula for the heating curve can be derived from the basic heat transfer equation:
Q=m.C.Delta(T)
Q is the heat added to the water (in Joules).
m is the mass of the water (in kilograms).
C is the specific heat capacity of water (approximately 4.18 kJ/kg·K).
T is the change in temperature (in Kelvin or Celsius).
To find the time required to heat the water, you can use:
t=Q/P
Where:
t is the time (in seconds) and P is the power input (in Watts).
I hope this would help to resolve it.
