How is the high vapor volume calculated?
Thread Content
I would appreciate it if experts could tell me how to calculate the amount of vapor generated when the black water from the vaporization furnace enters a high flash vessel. How does the specific heat capacity of water change with temperature without undergoing a phase change?
The mass and enthalpy are equal before and after flash evaporation; equations are established and solved. The specific heat capacity decreases with temperature up to about 44°C, and then increases.
Calculations based on mass balance and heat balance can be used to determine the mass and enthalpy of the high-flash black water entering the system; these values indicate the heat brought in by this black water. The total heat input is equal to the heat carried away by the high-flash black water exiting the system plus the heat carried away by the high-pressure flash steam
