Regarding water tank level adjustment
Thread Content
Dear sea friends, does anyone know what the various methods for adjusting the liquid level in the water storage tanks in the calcination section are, and what the advantages and disadvantages of each method are? Let’s share! Currently, self-regulating valve assemblies are widely used for regulation, but this often leads to delayed adjustments, inadequate control, numerous leakage points, and frequent maintenance.
If considering the instrument control hardware, that is the domain of the instrument control specialty. However, from the perspective of production operation management, I do have one piece of experience: it is essential to keep the pressure of the flash steam stable. In many plants, the flash steam systems are not connected to the main network (there are pipelines and valves, but their opening degree is low or they are not used at all in order to reduce internal steam consumption). Changes in the amount of steam used internally often affect the pressure in the flash steam pipeline system, which makes it difficult to use control valve assemblies and accelerates the wear and damage of these valves. The liquid level control in the water storage tank is extremely unstable, and both workshop managers and operators often turn to the instrumentation specialists for help.
Two-phase vapor-liquid flow: maintenance-free, low operating intensity, and few leakage points; the steam leakage rate is only 0.3%.
