The most important dimension in the design of vertical flash tanks is the internal diameter, which must be large enough to ensure a low discharge velocity of flash steam to minimize condensate carryover. If this velocity is low enough, the height of the tank is not important, but it is good

Automatic feedwater flow control for a monotube boiler. Author links open inexpensive and robust system for the electronic control of feedwater flow to a monotube boiler, as used in a small steam power system, is described. The situation is worsened if a monotube boiler is used instead of the conventional steam and water drum type. Here
