Study of Heat-Carriers Temperature and Enthalpy Distributions in Condensing-type Surface Heat-Recovery Units

摘要

A mathematical model of heat and mass transfer in surface condensing-type heat-recovery units (HRUs) is presented. An analytical solution is obtained that allows us to determine enthalpy, temperature, and moisture distributions. The solution is obtained under the assumption of a linear dependence of the saturated steam enthalpy on the wall temperature of the device. An analysis of temperature and enthalpy distributions is presented.
