Equivalent Evaporation | Advanced Steam Traction

Equivalent Evaporation might be more simply defined as “the quantity of water at 100°C that a boiler can convert into dry/saturated steam at 100°C from each kJ of energy that is applied to it. This defines it in terms of kg (of water/steam) per kJ of energy.

The principal shortcoming of pan evaporators is their low surface/volume ratio, resulting in poor evaporation capacity and extremely long retention time. Tubular heat exchangers (Billet, 1989; Minton, 1986) represent an attempt to fit more heat exchange area into an evaporator of a given volume.The tubular (shell-and-tube) heat exchanger can be installed either inside or outside the evaporator

Evaporation from Water Surface - Engineering ToolBox

2020-3-20 · Evaporation of water from a water surface - like an open tank, a swimming pool or similar - depends on water temperature, air temperature, air humidity and air velocity above the water surface. The amount of evaporated water can be expressed as: g s = Θ A (x s - x) / 3600 (1) or . g h = Θ A (x s - …

Boiler: Meaning, Development, Types and Calculations

“The evaporation which would be obtained if the feed water were supplied at 100°C and converted into dry and saturated steam at 100°C, at standard atmospheric pressure, is known as equivalent of evaporation from and at 100°C”. Evaporative Capacity: “It is defined as the amount of water and water evaporated into steam per hour”.
