On the evaporation of the water in the boiler, this oil is left as a thin film upon the heating surfaces, and by preventing the actual contact of water with the plates has been the cause of serious trouble. An attempt has been made to overcome the emulsion difficulty by uniformly mixing with the water a small quantity of solution of lime.

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.

Equivalent evaporation actually indicates the amount of heat added in the boiler for steam generation. Equivalent evaporation refers to the quantity of dry saturated steam generated per unit of time from feedwater at 100°C to steam at 100°C at the saturation pressure corresponding to 100°C. Sometimes it is called equivalent evaporation from and at 100°C. Thus mathematically it could be given as:

Equivalent Evaporation Advanced Steam Traction "For comparing the capacity of boilers working at different pressures, temperatures, different final steam conditions etc, a parameter called "equivalent evaporation" can be used. Equivalent evaporation actually indicates the amount of heat added in the boiler for steam generation.

The equivalent evaporation of a boiler is a measure to compare: A. the given boiler with the model: B. the two different boilers of the same make: C. two different makes of boilers operating under the same operating conditions: D. two boilers of same make but operaing under different conditions: E.

What are boiler efficiency and boiler evaporation ratio 2019-4-26 · Evaporation ratio = quantity of steam generation/quantity of fuel consumed.For example quantity of steam Is 310 ton/hr and fuel is 55 ton/hr then the evaporation ratio is 5.63.

Boiler blowdown is water intentionally wasted from a boiler to avoid concentration of impurities during continuing evaporation of steam. The water is blown out of the boiler with some force by steam pressure within the boiler. Bottom blowdown used with early boilers caused abrupt downward adjustment of boiler water level and was customarily expelled downward to avoid the safety hazard of showering hot water on nearby individuals. Surface blowdown is removed from the steam drum at the top of the
