Deaerator
and Feedwater Tank
The Alstom deaerator is
the result of many years
of experience in designing, engineering and
manufacturing the full
range of power plant
equipment. It is known
as a “spray, trays and
reboiling” unit, which
heats and deaerates the
feedwater.
Proven technology
for your plant safety and efficiency
To prevent corrosion, the feedwater supplied to the boiler and steam generators
of the thermal and nuclear power plants should not contain more than a few
micrograms of oxygen per litre water. The deaerator incorporated into the
feedwater heating circuit eliminates continuously the residual oxygen and
non-condensable gases contained in the condensate.
Customer benefits
Robust
The Alstom deaerator is designed to offer sustained reliability
across a wide range of operating conditions, including extreme conditions. It is also largely maintenance-free, which
means higher plant availability and greater cost-efficiency.
Versatility
A variety of different arrangements can be provided to fit all
types of power plants (fossil-fired, nuclear, combined cycle,
etc.) and all operating conditions.
Safety and efficiency
Optimized efficiency due to very small steam flow required
for venting and feedwater heating. There is no risk of water
return to the turbine. The Alstom deaerator offers good
deaeration over the entire load range.
Quality standards
The Alstom deaerators are subject to the company’s stringent
quality and design standards, which are applied to deaerators
as well as all Alstom power plant equipment.
