This short article runs through some of the features of standard built and use spray type deaerators. Note too that apart from the standard spray type deaerator, a tray type deaerator is also being used industrially. Standard spray type deaerators come in the form of vertical and horizontal designs. Both the vertical spray deaerator and horizontal spray deaerator (standard build) are composed of a single vertical tank.
In both cases, however, industrial users have the option to use a deaerator without pumps or a deaerator that carries a full pump package. Deaerators without pumps have higher capacity loads. But custom builds can go even higher, by as much as 800,000. And horizontal custom builds go even higher. Up to a capacity of 2,000,000. But without the pumps.
The vertical spray deaerator is applied to commercial and light industrial work processes. This favors those industrialists who have cost considerations to take into account and those who hold small floor spaces. The horizontal spray deaerator suits those who also have cost considerations to make but are dealing with ‘low headroom’. Speaking of space, this article has room for a quick comparison between spray type deaerators and tray type deaerators.
Experts believe that when dealing with temperature rises, use of the tray type deaerator is preferred. This is because high temperatures will always be required to allow spray type deaerators to perform at maximum loads. Also, in the case of the spray type deaerator, deaeration effectiveness drops when loads are increased. In this case, the experts say that the spray type’s heat/steam requirements are insufficient in order to maintain high steam flows.
Tray type deaerators have different operating principles in place, primarily for the release of gasses and they are also built with as many as 24 tray layers.
