Here is a brief outline of standard deaerators. You generally have two types of deaerators; the standard tray type deaerator and the spray type deaerator. All standard tray deaerators have a single vertical tank. There are also two tank alternatives and a bolted down double shell tray type deaerator. A standard vertical tray without pumps has the capacity to handle up to 200,000 standard units.
Custom prepared units, on the other hand, can manage up to 800,000 HR. The standard vertical tray type deaerator built with a pump package can manage up to 75,000 HR. These are industrial size and industrial use deaerators. They are all indicative of having power plant qualities. They are also designed in accordance with HEI requirements. The design carries a minimal plan area and achieves maximum turndowns and longer lifespans for the machines.
The two tank tray deaerator, built without pumps, also has a capacity of up to 200,000. But custom designs with two tanks in mind can achieve capacities of up to 250,000 HR. These two tank deaerators are applied in areas where only high quality and power plant gradings should be used. These machines also achieve low turndowns and longer lifespans. A bolted vertical heater (not deaerator) has horizontal storage capabilities.
A bolted double shell tray deaerator without pumps can be supplied to industrial users in two pieces. This makes it easier to transport and install at the industrial premises. This deaerator is suitable for use at central stations and those depots that take care of all domestic, commercial and industrial utility consumption. Tank capacities are also high, going as high as 200,000 HR, and the units are built in accordance with HEI requirements. Industrialists and manufacturers need to fully consider their operations before deciding whether to utilize trays or sprays.
