Sewage discharge rate of continuous sewage discharge expansion container

What is the sewage discharge rate of the continuous sewage discharge expansion container, or how to determine the gas production of the expanded water?
The continuous sewage expander is also called the continuous sewage expander. The design and manufacture should be in accordance with the pressure vessel GB150. http://www.ablfj.com/*ngimage/ Continuous layout diagram.jpg—98. The continuous blowdown expander is connected to the continuous blowdown port of the boiler and is used to depressurize and expand the continuous blowdown of the boiler. The blowdown water is adiabatically expanded and separated into secondary steam and waste hot water in the continuous blowdown expander. It is expanded, decompressed, and heat exchanged in the expander, and then discharged. The secondary steam is led out through a special pipeline, and the waste hot water is automatically drained away through the float level valve or overflow control valve. The heat energy can be recovered and reused. The continuous discharge volume is automatically adjusted as the boiler feed water load changes to maintain a relatively stable discharge rate. Therefore, the use of secondary steam and waste hot water as heat sources can recover part of the heat lost by continuous blowdown of boilers and improve boiler efficiency. The boiler wastewater is continuously and evenly connected to the wastewater expansion vessel. The wastewater moves tangentially in the cylindrical partition in the middle of the shell and is immediately vaporized into secondary steam. After passing through the upper shutter-type steam-water separator for steam-water separation, it is then introduced into the deaerator through the outlet at the top of the row, and the remaining wastewater is discharged through the water level regulating valve.
What is the discharge rate of the continuous sewage expansion vessel, or how to determine the gas production volume of the expanded water? The continuous sewage expansion vessel is actually a flash tank. The output of water or steam depends on the pressure of the flash tank. The amount of water and steam can be determined based on the enthalpy values of water and steam under this pressure.
