Overheating of water wall tubes may cause crack. Boiler will damage due to boiler drum level goes down.
Blow down is done in the boiler in case level is high in the boiler
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.
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 swelling and shrinking effect in a boiler drum refers to the physical changes in the drum's volume due to temperature variations and pressure changes during operation. When the boiler is heated, the water inside converts to steam, causing the drum to swell as the pressure increases and the water expands. Conversely, when the boiler cools down or experiences a drop in pressure, the drum may shrink as the steam condenses back into water. This phenomenon is important to consider for the structural integrity and safety of the boiler system.
Deaerator removes dissolved oxygen from boiler water. The condensate cascades down a number of perforated trays and its surface area is greately increased. This enables dissolved oxygen to come out. Further bleed steam is supplied to deaerator and due to this the atmosphere is predominantly of steam. So the partial pressure of oxygen above the water level is very very low. When a gas exists above a liquid level, the solubility gas in the liquid depend upon its partial pressure. So oxygen comes out of water. Deaerator outlet water has less than 0.05 ppm dissolved oxygen. This is furthe removed by dizing of Hydrazene (N2H2). =A.D.PALAMWAR

it all starts at the firebox and moves down to the boiler then out the pistons and the lefover steam goes up the stack.
As the steam releases thermal energy inside the radiator, it begins to cool down and condense back into water. This water then flows back to the boiler to be reheated and turned into steam again in a continuous cycle to provide heat.

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.
A steam boat is powered by the steam which turns the paddles or propellers. The steam is made by water being fed into a boiler which then heats up untill steam is produced and fed into a piston cylinder. The piston is pushed up by the steam, which is then released by a valve and it drops back down again.
The steam used in a fossil fuel power station is condensed back into water after it has passed through the turbines. This water can then be reused in the boiler to produce more steam for generating electricity.
If you are talking about a steam powered fire engine, for fire fighting, the answer is yes. If you are talking about a steam engine fed steam from a boiler, the answer is maybe. Some plants shut down their boilers nightly, others don't. Steam engines themselves however, do not use fire to operate, only boilers do.
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.
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.
