What is Surface Blowoff? - Definition from

Cited by: 23In the surface blowoff process, water is intentionally removed from boilers in order to prevent concentration of impurities while the steam is constantly evaporating. Water is blown off the boiler through steam pressure inside the boiler. Steam boilers typically need regular replenishment, as their supply of water is constantly evaporating due

Evaporator | Article about Evaporator by The Free

a heat-exchange device for evaporating liquids. In thermal power engineering, the evaporator is used to produce a distillate that compensates for losses of condensate in steam power plants. A tube vertical evaporator is usually heated by the steam coming from the turbine and passing through the space between the tubes.
