Blow down is done in the boiler in case level is high in the boiler
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.
The blow down used to remove sediment from the mud leg
By simply following the National Board of boiler Inspectors (NBBI) or the manufacturers instructions about the proper use of the blow down valves that comes with most 20th century heating units over 10 gallons
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 valves are needle valves designed for operation in open position. Their function is mainly to control a continuous flow of steam and/or water under high differential pressure. For that reason the design and materials must be such as to minimize the effects of a fluid stream in condition of flashing or made of water containing sometimes abrasive particles. They are used in Boilers mostly cases. There are two types of boiler blowdowns - continuous and manual. A continuous blowdown utilizes a calibrated valve and a blowdown tap near the boiler water surface. As the name implies, it continuously takes water from the top of the boiler at a predetermined rate A continuous blowdown is an optional feature and may not be included on your steam boiler. However, all steam boilers should include a means for manual blowdown as standard equipment. Manual blowdowns are accomplished through tapings at the bottom of the boiler. These openings allow for the removal of solids that settle at the bottom of the boiler. Manual blowdown is also used to keep water level control devices and cutoffs clean of any solids that would interfere with their operation. All steam boilers require manual blowdown whether or not they are supplied with continuous blowdowns.

Overheating of water wall tubes may cause crack. Boiler will damage due to boiler drum level goes down.
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.
The orgin of blow off some steam comes from old steam boilers. To let "off steam" or "blow off steam" would be to relieve the pressure in the boiler, to avoid risk of damage. When talking about a person, it means they are venting their thoughts, as a form of stress relief.To calm down and or from getting mad.
Blow-Me-Down Grange was created in 1839.
