There are two standard processes utilized. One uses the spray method. And the other makes use of a tray type deaerator. Standard tray deaerators all have a single vertical tank. Two types of tanks are built for these trays. One tray type deaerator being used is bolted down into a double shell. A standard tray deaerator can manage up to 20,000 standard units. But custom trays are being built for industrialists, processors and manufacturers. Such trays have the ability to handle as much as 800,000 units.
Standard vertically proportioned trays can handle up to 75,000 HR. The standard tray is of an industrial size mainly. It is built with power plant qualities in mind. The tray deaerators are designed in accordance with HEI requirements. Designs take into account a minimal plan area. They are looking at minimum turndowns and longer lifespans for the machines. A two-tank tray deaerator built without pumps can still manage up to 200,000 units. This type of deaerator is usually utilized in a space where high quality and power plant gradings are a requirement.
It can achieve low turndowns and has a longer lifespan. Bolted double shell tray deaerators built without pumps are provided to manufacturers and processors in two parts. This provision makes it easier to transport the equipment and have it installed at the designated premises. Pump-less deaerators are suitable for use at central stations and depots responsible for domestic, commercial and industrial utilities consumption. The tank capacity remains high with the 200,000 HR capacity being the norm.
Industrialists, manufacturers and processors do need to give due consideration to their industrial space before opting for a tray-type or spray type design. It is hoped that this outline of the tray type deaerator has been apt as a basic intro to the deaerator process.
