Analytical Model of an Exhaust Gas Cooling System Employing Liquid Injection

Abstract

An analysis was undertaken to better understand the phenomena occurring in spray coolers and to develop a mathematical model for comparison with experimental data from an operating unit. The physical characteristics of an operational exhaust gas spray cooler and the instrumentation systems are described. A mathematical model of a spray cooler was developed by assuming kinetic and thermodynamic equilibrium and one-dimensional flow. A mathematical model of a hypothetical, optimum cooler is included in order to have a basis for defining cooler efficiency. The equations were programmed for numerical solution on a digital computer, and several trial case runs are presented. Experimental measurements are compared with the efficiencies predicted by the mathematical models.
