High temperature gas hot water boiler steam drum with TUV For power
station CFB 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.
Boiler steam drum water level is one of the most important power
plant parameters to both measure and control. Control of the proper
water level in the boiler is critical for safe operation of the
boiler. If the level is too low, boiler tubes will be damaged by
overheating. If the level is too high, steam separators will not
function properly, temperature control will be difficult, and the
superheater tubes and turbine could be damaged by moisture or water
treatment chemical carryover.
In this circulation, the water flowing from upper drums through
downcomers which is located in the boiler is relatively cold, flow
down to mud drum. From mud drum, water flow back into the steam
drum after passing through the evaporator tubes.
In this forced circulation, fluid is pumped through the evaporator.
This causes the boiler can work with very high pressures.
