WALL-TO-LIQUID HEAT TRANSFER IN A LIQUID-SOLID FLUIDIZED BED
Abstrakt
A Multi-Stage-Flash/Fluidized Bed Evaporator (MSF/FBE) in which a fluidized bed heat exchanger is used represents an attractive process for water distillation.
The main characteristic of this type of evaporator is its vertical concept with short flash chambers accomodating a large number of parallel heat exchanger tubes.
Due to the liquid-solid fludized bed the wall-to-liquid heat transfer coefficient is enhanced in particular at low superficial fluid velocities. An early test apparatus was developed to measure the overall heat transfer coefficient to obtain a design equation for the construction of the first vertical evaporator with fluidized bed heat exchangers.
This paper deals with the development of a test apparatus to acquire more fundamental analysis of the heat transfer phenomena of a liquid-solid fluidized bed.
Explanation of an experimental set up for determination of the wall-to-liquid heat transfer coefficient is given. The independent variables in the total investigation include mass velocity, particle size and density, bulk temperature, wall temperature and tube diameter.
