A boiler twice as big (6x6x6) at the same pressure has 4 times the area and has a force potential of 21,600 in/pounds. Keep the boiler pressure fixed as you take away the steam volume to work (convert more water to steam) and you realize how much more work (Horse Power) the larger boiler can produce just because of its size.

A further alternative to having a boiler barrel (a steam and water container) for heating purposes, is to have what is called a mono-tube boiler or a flash steam boiler. This essentially is a single tube containing a small amount of water which is heated to the extreme, that way expanding the steam into dry steam where the pressure can be up to 2,000 lbs/sq.in or more owing to the heat input.

How a Steam Boiler Works. Steam boilers use a contained heat system to generate steam. The steam travels through pipes in the building’s walls where they emerge at radiators in heating systems. The radiators warm from the steam’s heat. As the steam gives off its heat, it condenses back to liquid water and returns to the tank.
slide 1 of 4. Introduction Scale formation in boiler due to the presence of various salts, which comes out of solution and deposited because of the effects of temperature and density.

Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator. A boiler or steam generator is used wherever a source of steam is required.
