three element means
1) drum level transmitter.
2) main steam flow transmitter.
3) feed water flow transmitter . in squared root.
we are controlling drum level by these 3 elements. output feed to 30% control valve. or control valve.

What is the difference between the operation of a automatic boiler and manual boiler?
boiler are working on same principal but automatic and manual boiler has difference that manual boiler working at single element loop and automatic boiler work at three element loop.single loop means when fuel increase mean load increase on boiler by adjusting fuel operator has to adjust steam drum level manualy , while automatic means when load increas, fuel increase steam drum level adjust automaticaly by watching fuel consumption.
What will happen when boiler steam drum level goes down?
Overheating of water wall tubes may cause crack. Boiler will damage due to boiler drum level goes down.
What is drum boiler?
A drumless boiler is obviously a boiler without a drum. The steam is fed into a header, then into a turbine for making electricity. Quality control of the water used is of extreme importance. Since there is no water level in a drum to maintain, feedwater must be constant with no interruption of any kind. With a drum type, water feed can be interrupted for a very short time. Not so with a drumless type.
High pressure steam boiler feed water p and id?
Usually high pressure boiler feed water is a 3 cell control using the drum level transmitters average, Steam flow Transmitter and feed water flow transmitter The drum level controller is tuned so that the drum level is around the half glass depending on load using the steam flow as a feed forward & drum level trim (lifting the drum level above SP under high load and lowering drum level under SP for low load)and the water flow to balance out with the steam flow (mind you if you blow down or have a tube leak the drum level will open the feed water control valve to maintain level) the main tuning in the P.I.D for this is Gain and integral not using derivative as it is too abrupt in its response obviously the actual full control schematics is a lot more complex than this
What is the use of steam drum in boiler?
The steam drum separated the steam from the water and stream mixture in the boiler drum.
What will happen if boiler drum level goes high?
the component seperator will not work and the cost of fuel will increase.
What is the purpose of boiler drum?
Purpose of the boiler drum is to collect steam from all the various tubes in a boiler, and send it to the turbine to spin the generator
Why is to safety valve mounted on boiler drum?
the safety valve is mounted on the top of drum because, if the water level in boiler decreases a certain value, the temperature gets increased in water drum because of lack of water. So, increase in temperature result in high pressure in steam drum, as the safety valve is designed to withstand a certain pressure, after a cetain pressure, the safety valve is removed by high pressure of steam. this is why the safety valve is mounted on top of boiler drum. +++ Shall we sort out that lot? That answer is wrong. Its only link with water-level is that the valve has to be above the water anyway. If the boiler runs dry the safety-valve will not protect it. The safety-valve is there to prevent the steam pressure rising to a potentially a dangerous level. It is set to open at the boiler's designed working pressure.

Why you use minus to zero range in drum level transmitter?
I refer to Steam Boiler drum level. It is actually - to some positive figure is the range. Generally the boiler level is maintained at mid point that is zero. The transmistter is differential type. (DP type) If the transmitter is with a specified signal out put of 4-20 mA, it sends out 4 mA at lowest level and 20 mA at highest level. At mid level zero it sends out 12 mA. Differential pressure is highest at actual lowest level and lowest at actual highest level of the drum. By keeping negative to positive range there is fair amount of analog signal on lower and higher side of the drum.
