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.
In a layman language, it's a steam generator. It's a closed pressure vessel in which fluid is heated to generate steam, also called (steam boiler). Open vessel, generating steam is not a boiler. So, its function is to transfer the heat produced by the combustion of fuel to water and finally to generate steam. i.e power generation.
Boiler and Pressure Vessel Safety Program | Mass.gov. The primary function of the Boiler and Pressure Vessel Safety Program is to manage the registration and inspection of all non-residential boilers and pressure vessels within the Commonwealth of Massachusetts.
Steam Pressure Reduction: Opportunities and Issues varies directly in proportion to the boiler’s net stack temperature (the difference between the flue gas tem-perature and combustion air temperature). When boiler pressure is lowered, a lower stack temperature results. This, in turn, causes slightly improved combustion efficiency.
The Boilers and Pressure Vessels Division is responsible for enforcing the Boilers and Pressure Vessels Ordinance (Cap.56) to ensure the safe operation of boilers and pressure vessels. Its major work includes : registration of boilers and pressure vessels ; carrying out spot checks on pressure equipment in work sites

Cold potatoes are ﬁlled in a big pressure vessel and hot steam is abruptly injected. The abrupt heat supply causes the potato peels to fall off so they do not have to be peeled by hand any more. Now, isn’t it tempting to fetch the old steam cleaner from the cellar and use it as a cooking aid? 8 | Industrial boiler technology for beginners
Jan 18, 2020 · Boiler safety valves are designed to prevent excess pressure, which is usually responsible for those devastating explosions.

10/27/2017 · Function of Steam Boiler. A boiler is defined as “a closed vessel in which water or other liquid is heated, steam or vapor is generated, steam is super heated, or any combination thereof, under pressure or vacuum, for use external to itself, by the direct …
Boilers are classified as either low pressure or high pressure and are constructed to meet ASME Boiler and Pressure Vessel Code requirements. Low-pressure boilers are limited to a maximum working pressure of 15 psig (pound-force per square inch gauge) for steam and 160 psig for hot water (2).
A high pressure steam boiler is boiler in which steam is generated at pressure exceeding 15 psig and operates hot water boiler above 160 psig or 250o F. Application this type usually is used for ...
A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially different from the ambient pressure (or simply atmospheric pressure). Gas cylinder in your house is a pressure vessel, an oxygen cylinder ..like that numerous examples. Boiler's function is just a closed vessel which heat a fluid.
Safety measures are to be taken care when the flow is continuous and pressure built up in the pressure vessel. For example in the boiler integral lines we have a high pressure steam drum which contains steam at top and water at the bottom in a mixed phase and maintains the operating pressure of 85 bar.

Feb 14, 2012 · In terms of an exploding pressure vessel with saturated steam I would expect the vessels shell to initially explode and be thrown apart in a similar way to an air explosion. But then the steam would very quickly condense when it hits the cool atmosphere, so there would be a reduced pressure wave. Testing an old vessel with steam just sounds crazy.
