Research on Heat Transmission and Wall Temperature of Cooling Wall Coiled Tubes in Supercritical Pressure Boilers.

Abstract The paper presents calculation and research results of heat transfer and wall temperatures of coiled tubes in the cooling walls of a 600MW supercritical pressure boiler. A relevant program for calculating wall temperature of coiled tubes in cooling walls has been developed as wall, which was used to calculate the medium's temperature at the cooling wall's exit, the wall temperature at different locations of the water walls heating surface, the heat transfer coefficient of the inner wall, as well as the enthalpy and temperature distribution of the fluid.
