Two-Dimensional, Two-Phase Numerical Model for Spray Dryers

摘要

This is the final report of a program to develop a detailed numerical model to simulate the desulfurization by spray dryers of the flue gases from coal fired power plants. The goals of this research were to supply a powerful analysis tool, a computer code called LDEF-SS, that permits the investigation of different spray dryer design concepts and operating conditions and hence provides a theoretical basis for optimizing performance and scaling up spray dryers. The bulk of this report is documentation for the LDEF-SS code. We also report the findings of an investigation we performed of the SO sub 2 absorption process. Due to funding limitations, we were unable to include the calculation of SO sub 2 absorption in the computer code. Nevertheless, the present version of LDEF-SS is a basis from which one can develop detailed models of flue gas desulfurization and many other industrial processes that use spray dryers.
