Abstract

The Danish Technological Institute and I. Krueger A/S have co-operated in developing a computer program MODS, to compute condensing flue gas coolers. The computer program focuses on the computation of crossflow/counterflow heat exchangers, and certain adjustments and manual calculations are required in order to use the program on flue gas coolers with parallel flow or parallel flow/counterflow coupling section by section. The computer program computes performance and temperature data, amount of condensate and pressure loss in connection with complete or partial condensing flue gas cooling. Through laboratory tests it has been demonstrated that the measured values are in keeping with the computed values within an average uncertainty margin of approx. 8% with regard to the determination of output while full-scale plant measurements have shown somewhat larger discrepancies between the measured values and the computed data. The computer program must be partly reconstructed and adjusted to try to achieve better agreement between measured and computed values. The computer program can with advantage be upgraded to be able to handle an arbitrary coupling variant (parallel/counterflow). (au)
