Back Washing Plate Heat Exchangers | Shell & Tube Heat

Automatic backwashing systems reverse the flow and backwash the shell-and-tube or plate-and-frame exchangers. The reversal of the flow direction and the increase of the (local) flow velocity fight have the following effects: They end up in the heat exchanger and can stick and settle in the low flow areas. Cannot stick if flow > 0.2 m/s. Low

Heating System Gauges: Pressure and Temperature Gauges on

The temperature/pressure gauge may help in checking for normal conditions before and during boiler operation. However the boiler pressure or temperature gauge can be wrong! This boiler pressure and temperature gauge shows a typical in-boiler pressure of under 20 psi, and a temperature of about 190 °F.

Putting Condensate Polishing Issues to Bed - Deep-Bed

Step I Backwashing. This is accomplished by passing water upward through the bed for 1020 min at a velocity of 715 m/h sufficient to expand the bed by 50. Backwashing removes particulate matter, relieves any bed compression, and allows trapped gases
