Before firing a cold boiler with no steam pressure, the air cock is opened to allow air to escape during the heating of the water.
The furnace and tubes are within a larger vessel, which contains the water and steam. The firetube construction provides some characteristics that differentiate it from other boiler types. Because of its vessel size, the firetube contains a large amount of water, allowing it to respond to load changes with minimum variation in steam pressure.
things, the use of steam receivers. Steam receiver means any vessel used for containing steam under pressure greater than atmospheric pressure and covers equipment such as a vessel used to store steam for heating of other materials (i.e. dryers, steam rolls etc.), or for heating of fluid under pressure in a vessel as kiers. 2.
upon the ratio of boiler feedwater makeup to returned condensate and the operating pressure of the deaerator. Deaerators use steam to heat the water to the full saturation temperature corresponding to the steam pressure in the deaerator and to scrub out and carry away dissolved gases. Steam flow may be parallel, cross, or counter to the water flow.

What is the pressure of a high pressure boiler?
Another example of an unfired pressure vessel is a steam generator that is related to the piping systems for producing steam. Steam generators are used more often than boilers in generating steam, since these are safer alternatives and capable of reducing the extent of damage associated with corrosion.
One function: to safely heat water. Whatever the resulting hot water or steam is used for is not a function of the boiler, but the system it is connected to.
The rate at which the water flashes to steam is a function of the storage pressure, and the rate at which steam is required by the system being supplied. Charging.
