| Abstract: | A new type evaporator with double separation chambers and double tube passes was established to solve the problem of reduced heat transfer coefficient for the evaporation material that viscosity changes greatly with the concentration.The whole separation chamber is divided into two sub-chambers and each sub-chamber has double tube passes in tandem.Glycerin and water solution was applied to the hot state experiment,and the average heat transfer coefficient was studied in the conditions of different heat flux... |
