The water is blown out of the boiler with some force by steam pressure within anticipating those particles will settle to the bottom of the boiler.
Blow down is done in the boiler in case level is high in the boiler
Overheating of water wall tubes may cause crack. Boiler will damage due to boiler drum level goes down.
ANSWER: If it's a steam boiler: Once a month. If it's a forced hot water boiler-You don't have to. You'll only be adding more air into the system causing more noise.
The blow down used to remove sediment from the mud leg
Boiler can be classified as below
Boiler waterwalls should typically be blown down daily or as needed, depending on the operating conditions and water quality. Regular blowdowns help remove sludge and sediment buildup, which can affect heat transfer efficiency and lead to corrosion. The specific frequency may vary based on the boiler's design, water chemistry, and operating procedures, so it's important to follow the manufacturer's recommendations and monitor water quality regularly.
The boiler light may not be on due to a malfunction in the electrical system, a blown fuse, or a problem with the boiler's ignition system. It is important to troubleshoot and address the issue promptly to ensure the boiler functions properly.

Cycles are a measure of the dissolved solids in the boiler water in relation to the dissolved solids in the feedwater. For instance, if the measure of chlorides in the feedwater sample is 5 ppm and the chlorides in the boiler water sample is 50 ppm then the boiler water has been cycled ten times, 50/5 =10. That means that all of the water in the boiler (plus all the water that has been blown down) has been evaporated completely ten times, and replaced by the same amount of feedwater. Steam does not carry the dissolved solids out of the boiler, they remain behind, these are controlled with water treatment and a continuous blowdown (bottom blowoffs control or remove suspended solids).
Blown over, blown down, yes, but not blown away.

Blown is the past tense of blow. "The wind had blown down the tree in our yard."
