PROBLEM TO BE SOLVED: To provide an analyzing device and an analyzing program, capable of analyzing a state of heat transfer in a reactor having a plurality of heat transfer tubes for flowing a heat transmission medium arranged therein in a short time.SOLUTION: A cross section of a fluid layer of a reactor is represented by S and the height represented by H to realize two-dimentional space. The space is horizontally divided into two parts corresponding to a ratio between an interfacial area of heat transfer tubes through which a heat transmission medium at a temperature equal to or lower than the boiling point flows and an interfacial area of heat transfer tubes through which a heat transmission medium at a temperature above the boiling point flows. Further, the space is vertically divided into two parts, i.e., a region where heat transfer tubes exist and another region. Based on the heat balance relation between zone B1 and zone B2, the heat balance relation between zone B1 and zone E1, the heat balance relation between zone B2 and zone E2, and the heat balance relation between zone E1 and zone E2, temperature of each zone is calculated.
