WebJun 20, 2015 · The evaporation rate depends on the surface area of your brew kettle, the rate of boil (e.g., rolling boil), and to a lesser extent, the altitude. A percentage can be accurate if you always boil the same volume in the same kettle at the same rate, but as soon as you change one of these variables that percentage will be wrong. http://www.cfbcboiler.com/what-are-boiler-efficiency-and-boiler-evaporation-ratio.html

WebJun 1, 2016 · Indeed, you can write. J = K ( c − c s), where J is the evaporation flux, c the concentration of water vapor in the air and c s the concentration of saturated water vapor at the given temperature. The problem is that generally, c will not be constant over the position (if you blow dry air into the x direction, then c = 0 at x = 0 and c → c ... WebBoiler heat exchanger effectiveness is specific boiler thermal efficiency, which is converted to heat energy from the fire side to the water side. ... L 2 is the percentage of heat loss owing to the water evaporation. Tf is the temperature of flue gas, o C. C p is the specific heat of superheated steam, ... continuous blow down rate. ... WebEvaporation can be defined as the process through which a liquid (generally water) is converted into a gas/vapour without being heated to its boiling point. The key factors that affect the rate of evaporation of a liquid are: Temperature: The greater the temperature of the liquid and its surroundings, the faster the rate of evaporation.
