The Process of Evaporation | National Geographic Society
21/01/2011 · Evaporation happens when a liquid substance becomes a gas.When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. Evaporation is a very important part of the water cycle.Heat from the sun, or solar energy, powers the evaporation process.It soaks up moisture from soil in a garden, as well as the
Water evaporation occurs because, at high temperature, water molecules vibrate rapidly, which results in some of the molecules gaining enough energy to escape from the lattice network of water molecules.

Oil fired central heating is popular in properties in rural locations where there is no direct access to the mains gas grid. Oil is a highly efficient fuel giving good return on every unit of energy, with an efficiency rate of over 90%, these oil boilers will help to keep your energy bills down.
Vacuum Evaporation Sources • Physical evaporation A source container is heated. The material to be evaporated is placed in or near the source. The radiative and conductive heating evaporates the source. • Electron beam evaporation A filament is heated and
15/05/2015 · evaporators (Figure 3, next page) in the pulp mill is to evaporate the water content of the weak black liquor leaving the pulp washers to a sufficient concentration to allow firing and combustion of the liquor in the recovery boiler. To evaporate the large amounts of water contained in the weak black liquor from the pulp washers (15 to
the boiler operating when the water level is low, but allows the boiler to restart and resume operation once the water has risen to an appropriate level. The second low-water-level alarm is triggered at a lower level than the first and this shuts the boiler down completely and requires a manual restart.
