Abstract

A transparent multi-tube vapor-liquid-solid circulating fluidized bed evaporator was built to research the thermal efficiency under different conditions. The effects of circulating flow rate, heat flux, the amount of additive particles and properties of particles on the thermal efficiency in the evaporator were investigated. The results show that as the circulating flow rate, additive particle amount and heat flux increase, the thermal efficiency increases; and thermal efficiency increases significantly with the increment of heat flux, which indicates that heat utilization is better at high heat flux. While the density and thermal conductivity of particle increase, the thermal efficiency also increases. A circulating pump was used as forced-circulation equipment, and the power consumption of pump increases modestly with the increment of additive particle amount.
