| Abstract: | Heat transfer and scale inhibition were studied for gas-liquid-solid three-phase flow boilingwhich was formed by introducing a small amount of inert gas and solid particles into flow boilingliquid. The experimental results show that heat transfer is much enhanced with the introduction of theinert gas and fluidized solid particles. Scale can be effectively inhibited in the three-phase flow boilingand "on-line cleaning" of the heating surface can be realized. |
