Drain flow rate and parameter control of the steam drum, as well as recycling methods
Thread Content
Everyone, what is the typical discharge flow rate for the continuous drainage from hydrogen production steam drums in various companies? What should the control limits be for the water quality analysis parameters of the drainage water? (Such as conductivity, iron ions, silicon content.) Do anyone have any good experiences or suggestions regarding the recycling of drum drain water? ? Thank you
In a tandem arrangement, discharge occurs sequentially, with the outlet located right above the liquid level, allowing the floating scum on the surface to be removed
For the boiler water quality parameters and emission levels of hydrogen production facilities, GB/T1576 (Chemical dosing in boilers) can be used as a reference. Regarding the drainage water, depending on the scale of the facility, if it is large-scale, flash evaporation of this drainage water is employed to recover low-pressure steam, which can then be used as heating steam in thermal deaerators. In smaller-scale facilities where the amount of drainage water is low, flash evaporation is not necessary; instead, circulating water is used for cooling before the water is discharged into the factory’s wastewater system.
It has been learned that, within the specified range of indicators, economic efficiency also needs to be taken into account
