The floating head on a floating heat exchanger can be of different types depending on requirements. To reduce thermal stresses and provide a way to remove the tube bundle for cleaning, different floating heads have been designed. Below are four basic types.. Split Back Ring (Type S) A Split Back Ring type unit is most commonly used in industry.

Working Of Solar Drying. The principle of the solar drying technique is to collect solar energy by heating the air volume in solar collectors and to lead the warm air from the collector to the drying chamber. The products to be dried are placed in the drying chamber. The basic principles employed in a solar dryer are:

How Does It Work. The floating ping-pong ball is a wonderful example of Bernoulli's Principle. Bernoulli, an 18th-century Swiss mathematician, discovered something quite unusual about moving air. He found that the faster air flows over the surface of something, the less the air pushes on that surface (and so the lower its pressure).

The general working principle of desiccant air dryers is simple: moist air flows over hygroscopic material (desiccant) and is thereby dried. The exchange of water vapor from the moist compressed air into the desiccant causes the desiccant to gradually be saturated with adsorbed water. Therefore, the desiccant needs to be regenerated …

The principle of vibrating fluidized bed drying: the natural air is taken from the dry air, and the natural air is passed through the air filter by the blower and then heated to the set temperature by the heat source such as the steam heat exchanger or the electric heater (the temperature is determined according to the characteristics of the ...

The working of a float switch is based on the principle of buoyancy i.e., when there is no liquid in contact with the float, it floats on top of the liquid surface and triggers an alarm signal, when there is a sufficient amount of liquid in contact with float, it submerges itself into liquid and stops alarming. The principle of operation is the ...

The rotary dryer's drum is a slightly angled and rotatable cylinder with wet material entering from one end up and dry material collecting from the other end down. Hot air enters at the inlet or outlet end and exits at the top of the other end. The barrel is equipped with a forward-running plate, which makes the material to be continuously run …

A feature of this design is complete isolation between the electrical components and the "wet" components sensing the liquid level. The steel rod moves inside a non-magnetic metal tube, with the tube sealing process fluid pressure from escape while still allowing the magnetic tilt switch to sense float position.

Gently place ping pong ball above the hair dryer; The ping pong ball will float about the hair dryer, spinning and bobbing gently, but will not fly out of the air stream. The moving column of air produced by the hair dryer causes an area of low pressure (due to the Bernoulli Principle as explained below).
