If yourmill has a boiler producing saturated steam at, say, 250 psi andyou are using steam at your dry kilns at 100 psi (which has beenreduced from 250 psi through a pressure reducing valve), the steamwill be 407Â°F, not at the saturation temperature of 338Â°F for 100psi steam.

Plate tectonics is the theory that the outer rigid layer of the earth (the lithosphere) is divided into a couple of dozen plates that move around across the earth's surface relative to each other, like slabs of ice on a lake.est Answer: the theory that the earth is made of massive plates beneath the surface that move every so often which is how we get earthquakes. and this also goes back to Pangea if you know what that is.

There are three main types of plate boundary: divergent, convergent and transform. Plates move away from one another at divergent boundaries. This happens at mid-ocean ridges. Plates move towards one another at convergent boundaries; one plate is forced below another in a process called subduction. Earthquakes and composite volcanoes are common at this type of boundary. Plates move past on another at transform boundaries. The most famous example of this type of boundary is the San Andreas Fault in California.
