Steam—chapter_efficiency

2007-9-18 · Hence, one boiler horse power is equal to an evaporation of 34.5 pounds of water per hour from and at 212 degrees Fahrenheit. The term boiler horse power, therefore, is clearly a measure of evaporation and not of power. A method of basing the horse power rating of a boiler adopted by boiler manufacturers is that of heating surfaces.

Evaporation Article about Evaporation by The Free …

evaporation, change of a liquid into vapor at any temperature below its boiling point boiling point, temperature at which a substance changes its state from liquid to gas. A stricter definition of boiling point is the temperature at which the liquid and vapor (gas) phases of a substance can exist in equilibrium.

Safe management of industrial steam and hot water boilers

2018-11-1 · Safe management of industrial steam and hot water boilers Water treatment As with all systems where water is heated there will be a potential for scaling. This can lead to a loss of efficiency or, in extreme cases, premature failure of the boiler due to either scale build-up on the internal surfaces or debris from corrosion

Evaporator – Wikipedia

2019-11-11 · Evaporation can be distinguished from some other drying methods in that the final product of evaporation is a concentrated liquid, not a solid. It is also relatively simple to use and understand since it has been widely used on a large scale, and many techniques are generally well known.

Boiling – Wikipedia

2019-11-23 · Evaporation only happens on the surface while boiling happens throughout the liquid. When a liquid reaches its boiling point bubbles of gas form in it which rise into the surface and burst into the air. This process is called boiling. If the boiling liquid is heated more strongly the temperature does not rise but the liquid boils more quickly.

Which Factors Affect Evaporation? Reference.com

At a high humidity, the rate of evaporation is also low. A high rate of airflow increases evaporation. Large surface areas also facilitate evaporation. An increase in temperature facilitates evaporation by increasing the kinetic energy of the evaporating molecules. However, strong intermolecular forces or bonds reduce the rate of evaporation.
