Apr 20, 2011 · 15 Apr 11 17:07. I have seen that most small boilers (below 100 ton/h of steam) are "bottom supported" design, while bigger boilers are "top supported". I am trying to understand which variables impose the use of the more expensive top supported design, even in places without seismic loads. I appreciate if someone could give references of

Why the boiler in thermal power plant is top supported

All of pressure parts assemblies of steam boiler are supported from top; they are suspended like a church bell. The weight of load and expansion are transferred to the ground. Top supported structure is usually more expensive than bottom supported.

Dec 18, 2002 · Steam is a gas that will eagerly condense on cold metal. The boiler must be able to make enough steam to reach the furthest radiator before all the steam turns to water. In other words, the boiler's ability to produce steam must match the system's ability to condense steam. If the boiler is too small, parts of your home will always be cold.

BFB boilers are ideal for a wide range of biomass and high-moisture waste fuels. B&W's bubbling fluidized-bed (BFB) top- or bottom-supported, one- or two-drum designs prove attractive in new or retrofit applications. Capacities for bottom-supported range up to 225,000 lb/h (28.4 kg/s) and top-supported from 225,000 to 1,000,000 lb/h (28.4 to 126 kg/s).

CFBC (circulating fluidization bed combustion )BOILER

A steam drum is a standard feature of a water-tube boiler.It is a reservoir of water/steam at the top end of the water tubes. The drum stores the steam generated in the water tubes and acts as a phase-separator for the steam/water mixture.The difference in densities between hot and cold water helps in the accumulation of the "hotter"-water/and saturated-steam into the steam-drum.

The top tube sheet in a steam boiler can be above or below the water line. When it is above, it is called a dry-top and when it is below, it is called a wet-top. A vertical boiler has a small "footprint" and can be installed in boiler rooms with limited space. Vertical boilers are very popular in the dry cleaning industry.
