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.
Blow down is done in the boiler in case level is high in the boiler
You should blow down a hot water boiler regularly, typically once a week during the heating season, to remove sediment and prevent buildup. However, the frequency may vary based on water quality and usage; some systems may require more frequent blowdowns. Always consult the manufacturer’s guidelines or a qualified technician for specific recommendations tailored to your boiler. Regular maintenance helps ensure efficient operation and prolongs the boiler's lifespan.
The blow down used to remove sediment from the mud leg
Call the water board, if you can't turn the pressure down on the boiler.
Overheating of water wall tubes may cause crack. Boiler will damage due to boiler drum level goes down.

The blow down used to remove sediment from the mud leg
When blowing down a boiler, the proper sequence is to first open the blow-off valve slowly to allow for a controlled release of pressure and water, followed by opening the blowdown valve. After the blowdown is complete, close the blowdown valve first, then close the blow-off valve. This sequence helps prevent potential damage and ensures safe operation by managing pressure changes effectively.
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.
A "blowcock", also known as a "blow-off valve" is a cock (valve) in the blow-off pipe of a boiler. Since blow-off valves are installed at low points of the boiler water system, it is obvious that one of their principal uses is to help remove suspended solids or impurities, particularly those that tend toward sedimentation. Secondarily then, it is also obvious that is blowing down, a portion of the boiler water is discharged thereby reducing the water level in the boiler. This function therefore aids as a safety measure, in avoiding carryover of water from the main steam drum in the event of high boiler water-level for whatever reason. A third use of these valves, but far less frequent, is the introduction of boiler cleaning acid to the boiler, and again draining of this acid after the boiler is acid-washed. Many boiler operators choose to pump this fluid through the blow-off valves, since they usually are a handy means of ready access to the boiler.In the case of a car, the "blow cock", aka blowoff valve(BOV) or dump valve is a pressure release system present in most turbocharged engines. Its purpose is to prevent compressor surge, and reduce wear on the turbocharger and engine. Blowoff valves relieve the damaging effects of compressor "surge loading" by allowing the compressed air to vent to atmosphere, making a distinct hissing sound, or recirculated into the intake upstream of the compressor inlet.

Of course it can fail. Look at the temperature of the water in the boiler, turn the stat up and down. You should hear a slight click when the temperature setting and the boiler water temp are appx the same if you do, the stat is probably good. You can verify this with a voltmeter.
Overheating of water wall tubes may cause crack. Boiler will damage due to boiler drum level goes down.
If you are using water and not steam there should be a temperature controller mounted in the side of the boiler, that is where the start and stop point of the boiler is controlled.
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.
It didn't blow down. It burned down in 1936.
