Why Three Element method for Boiler Drum Level Control | Single Element Control |Steam & water Flow

The term “3-element control” refers to the number of process variables (PVs) that are measured to effect control of the boiler feedwater control valve. These measured PVs are: liquid level in the boiler drum, flow of feedwater to the boiler drum, and. flow of steam leaving the boiler drum.

Sir explain what are the functional block that used in dcs can you explain and how it error generated

[@WAQASMAHMOODEngineer]

What is the normal position of boiler feed water control valve, normally open or normally close

[@monishvasu3292]

fail open

[@shravanimore8671]

Why are there bubbles formation due to less pressure inside the drum?

[@ElectricalAndautomation_guru]

Hit concentration of solids inside the boiler at the low pressure.

[@cliffordswamy2409]

I hav a doubt but a good one,u n many said about swell n shrink of water inside boiler,n u said that due sudden steam load the water swells n thus gives high level n vice versa,my point is that the level transmitter measures the head(weight of liquid) of the level inside boiler ,if at certain constant pressure, temperature and flow if theres a sudden load pickup the costant volume of water swells but at that instant the mass remains the same so how come the level transmitter reads higher level when the mass of water remains the same n just the volume swells,in other words if i boil 1 ltr of water at 100 c by clossing the lid and suddenly opening it the water swells but the wieght or mass remains the same or may be less,that means the force applied at the bottom of the vessel will always remains the same no matter how much the water expands or swells this particular finding is true but its very contradictory to the practical of the boiler cud plz elaborate and clear this doubt of mine that hows that possible, when volume of water increases the weight of the water also increases.

[@ElectricalAndautomation_guru]

Look, you understand this very correctly. Let me clear your confusion in this way. When the demand of steam suddenly increase then it will creates the drum level high but because the steam present in the drum suddenly gone at this position the water supply should decreases, as per logic but this will get rectified by the steam flow data.

[@ElectricalAndautomation_guru]

Bubble size is affected by pressure, so if a boiler experiences a sudden extra demand for steam, its pressure drops. The drop in pressure causes the steam bubbles in the boiler water to expand, and the level measurement can show an increase in level.

[@ElectricalAndautomation_guru]

Here are the two factors pressure and temperature which creates the different scenario from the normal situation that you told in comments
