There will of course be numerous break downs in terms of the different kinds of deaerators in use. This of course all has to do with the different industrial sub-sectors it is feeding. But in the main, the tray type deaerator could be categorized in the following ways. Three tray type examples follow. These are the vertical tray deaerator, also known as a single vertical tank, the tank car tray and the bolted double shell tray.
The vertical tray (VT) deaerator has no pumps. A tank car tray deaerator also comes equipped with two tanks. And the bolted double shell (BDS) tray deaerator is also packaged as a bolted vertical heater with horizontal storage capacity. But in each of the three cases here, the unit per hour capacity is high. Vertical tray deaerators can, however, be optional with a pump package included, but in this case the abovementioned capacity will be much lower in comparison.
Power plant quality applications are being designed in accordance with HEI requirements. Tray units require a minimal plan. Tank car tray deaerators can be applied to all those areas where high quality and power plant grade use is required. Like the abovementioned VT deaerator, the tank car tray deaerator has little downtime and is capable of long lifespans. In all three aforesaid cases mentioned thus far just note that where unit per hour capacities are lower than standard even, the industrialist can arrange for a customized alternative, in which case he will be able to produce his required capacity.
The bolted double shell (BDS) deaerator, with or without pumps, does however, have high capacities for the user. The standard and custom design can be prepared in accordance with HEI requirements. The tray unit will be shipped to the industrial site in two sets mainly for easier shipping and installation.
