Моделювання роботи теплообмінних апаратів систем енерго- та теплопостачання високотемпературних технологічних установок

Abstract

The mathematical model of the heating processes in the regenerative heat exchangers with stationary refractory checker-work used for the combustion air pre-heat in the high-temperature heat engineering installations is presented. On this base the procedure simulating the hot-air stoves operation with allowance for technological and operational limitations is created. This makes possible to determine the heat transfer agents and checker-work temperatures in time intervals and in heat exchanger height. The data obtained can be applied for selection of the regenerators’ structural and processing properties during the reconstruction of the operating units as long as in designing of the modern high-temperature heat engineering equipment.
