A vapor - liquid - solid three - phase circulating fluidized bed

which is a new type of evaporation boiling means

has been studied. The experimental results show that it has the abilities of enhancing heat transfer

preventing from and cleaning fouling. Under the same conditions

its heat transfer coefficient is 1.5-2.0 times that for the two - phase flow boiling heat transfer. Meanwhile the effects of different particles (glass

ceramic

steel and titanium particles)

particle concentration

liquid flow rate and heating vapors pressure on boiling heat transfer are studied. The investigative results in this aspect are not reported so far.
