Oxygen (O2) and carbon-di-oxide (CO2) gases solved in boiler feed water are excess corrosive gases and causes corrosion on boiler sheets and tubes. They can create small holes on tubes and sheets in short time like 6 months if they can not be eliminated from boiler feed water. The amount of CO2 in feed water should be zero and O2 below 0.05 mg/liter.
ARALSAN deaerator is the best solution to eliminate corrosive gasses in boiler feed water.
Old model dearator consists of a huge condensate tank, a huge deaerator tank and a deaerator drum.
Tons of water are accumulated in both tanks that means a lot of heat consumption and heat loses and a lot of place.
Flash steam can not be recoved at old model deaerator system and a flash tank is tried to sold you for utilization of flash steam in deaerator. It means extra investment cost.
Condensate tank and deaerator tank are combined at ARALSAN COMPACT DEAERATOR and deaerator drum is a flash steam tank at the same time.
Flash steam of condensate is used to heat deaerator without using any other equipment.
In this case the investment amount and necessary place are reduced. That means your money is saved by reducing investment and operation costs.
