2020-5-7·In the modern water-tube boiler, separation of the steam-water mixture entering a relatively small steam drum is a complex process. For every pound of steam generated, as many as 15-20 lb of water may circulate through a drum. As a result, 99.97% or more of the circulating water must be removed from steam to ensure the desired steam purity.
Get a QuoteIn the water tube boiler the upper drum (Boiler steam drum) provides for separation of steam from water. It also provides liquid holdup capacity (typically 10 to 60 seconds) to allow for a dynamic response to load changes without losing liquid in the downcomer and riser tubes. The size of the steam drum

The 10.5 :1 circ ratio implies that for every 1000 lbs of steam generated, there will be 10.5*1000 lbs of water circulated thru the waterwall tubes, to prevent overheating of the waterwall tubes.

Get a QuoteAs water passes through the coil, the heat is transferred from the hot gases which causes the water to convert to steam. The generator design does not utilize a steam drum where the steam of a boiler has a disengagement area from the water in so the use of a steam/water separator to achieve 99.5% steam quality is required.

Get a QuoteIn small, low pressure boilers, steam-water separation can be established with the use of a large steam drum approximately half full of water.Natural gravity steam-water separation can be sufficient for this case. On the other hand, for high capacity, high pressure (HP) boilers, steam-water separation at the steam drum is accomplished with the use of mechanical steam-water separators.

Entrained boiler water contains dissolved or suspended solids, which affects the steam purity. Carryover results from incomplete separation of water from steam- water mixture.
