Thermal efficiency evaluation for multisection heat exchange equipment in heat power installations

Abstract

Comprehensive approach to improving heat exchangers for heat recovery and utilization of heat power installations is achieved by applying a step-by-step heat exchange process to be implemented in multi-section heat exchange equipment. Determination of its optimal structural, design and layout parameters can be carried out taking into account various criteria, including the use of the thermal efficiency function. Expressions for the thermal efficiency function of the objects under study are obtained in the form of complex, non-uniform heat exchange systems, on the basis of which the method for evaluating their execution options is developed. Optimal sequences of heat exchange sections, heat load distribution and operating modes for this equipment are determined.
