Steam Generator vs. Steam Boiler | Powerhou

The water flows through the smaller diameter boiler tubes while the combustion gases travel around them to transfer heat to the water. The boiler tubes in the watertube design carry the heated water inside the tubes between the lower drum (mud drum) and upper drums (steam drum), with the generated steam accumulating in the upper drum.

Drum sizing estimation - Boiler and Pressure Vesse

2003-2-24 · The steam and water are separated by a combination of cyclone separators and demisters. Each of these 2 components has a capacity based on operating pressure and required steam purity leaving the drum. If the boiler is a "natural circulation" boiler, then one also must limit the allowable pressure drop thru the separator to not more than 2 ft

Relying on the size of the drum to effect the steam separation in a high pressure boiler would require a very, very large steam drum indeed (assuming it would even be possible) due to the increasingly narrow gap in enthalpy.

2003-10-30 · Forced and natural circulation boilers: the pressure drop in the evaporator part of drum-based boilers does not affect the pressure loss of the main steam/water flow through the boiler. This means that saturated steam leaving the steam drum has the same pressure as the feedwater entering the steam drum. The pressure loss of the evaporator has to be
