GET A QUOTE### What is an Evaporation Rate? - Definition from

Evaporation is an endothermic process that changes liquid into a gaseous state of matter before reaching the boiling point of the liquid. Evaporation rate is linked with many factors such as surface area, temperature of the liquid and surrounding air. A system's evaporation rate slows down once the vapor pressure achieves equilibrium.

GET A QUOTE### Is the predicted Evaporation Rate for the 5AT realistic

The higher boiler evaporative heating surface area per m 2 of grate of the 5AT will increase the evaporation rate per m 2 of grate area compared to 3450. You have 4 reasons above why the 5AT would have a higher evaporation rate per m 2 of grate area compared to 3450. There are also more esoteric ones, but the above is enough I think.
