Abstract: On the basis of the multidimensional transient heat transfer differential equation, two-dimensional transient heat transfer governing equation in the cylindrical coordinate was derived. Fully implicit discretion equation of inner nodes and discretion equation of boundary nodes by means of additional source term method were built up. Taking cokes in coke drum as the research object, a simplified middle-channel model was built up. Then the mathematical model established in this paper was numerically analyzed using finite volume method. Visual Basic 6.0 was used to program to calculate the temperature fields of cokes in coke drum. On the assumption that the exothermic amount of coke is equal to the heat absorption amount of water, the calculated vaporization amount of water 1.4~12.0t/h is close to the flux range of condensated water 4~15t/h.
