Boiler Drum Level Control - Chemical Engineering World

Drum drying: in drum drying, the heated surface is the envelope of a rotating horizontal metal cylinder. The cylinder is heated by steam condensing inside, at a pressure in the range of 200 to 500 kPa bringing the temperature of the cylinder wall to 120–155°C. The wet material is applied on the drum surface as a relatively thin layer by a variety of different methods to be described later.
