ON THE THERMAL STATE OF A CONDENSATION HEAT EXCHANGER

Within the framework of a model of a heat-releasing structured granular bed, simulation has been conducted of the heat-transfer processes in a gas-tube heat exchanger in the presence of water vapor condensation in the vapor–gas mixture. A functional dependence of the heat fl ux used for heating water on the geometric and hydraulic parameters of the heat exchanger has been established.
