Statement and personal-computer-aided realization of the conjugate problem of heat transfer in a power-technological boiler with a moving bed of dispersed heat-transfer agent

Abstract

Consideration is given to the statement of the problem and principles of personal computer-aided realization of the thermal-calculation method for a steam generator-utilizer of the heat of high-temperature coke or other loose medium with known thermophysical properties.
