For softening calsium or magnecium hardness and its become slury, other effect is by used phosphate can increased the Ph value.

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.
In the steam drum, where steam exits and flows to the superheaters.
the decay of boiler material by chemical or electrochemical attack by its environment is known as boiler corrosion
one of the main purpose of refractories in the boiler furnace is to

Na3po4 dosing boiler drum is used mainly for two things. To soften calcium and magnesium to make them slushy and to increase phosphate.
The steam drum separated the steam from the water and stream mixture in the 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
boiler drum diffferential pressure level calculation explained
Generator
Overheating of water wall tubes may cause crack. Boiler will damage due to boiler drum level goes down.
as the boiler drum is cylindrical in shape due to low stress concentration and in both end the diameter will be less.so for easy entry into the drum for a man the drum man hole is elliptical in shape.

This is due to steam seperation the silica remains in the drum water.

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.
