A mathematical model for the temperature field in a glass furnace regenerator

A mathematical model for the temperature distribution in a glass furnace regeneratorhas been proposed on the basis of heat balance. For the establishment of the model, thethermal parameters concerning the flowing gases with that of the checker bricks as well asthe heat transfer coefficients are taken into consideration as the functions of the tempera-ture. The local surface temperature translated from the local mean temperature of thechecker on the nodes was used to calculate the heat transfer coefficients, and the lumpedheat transfer coefficient was adopted to embody the effects of the intraconduction of thechecker brick. The above mentioned governing features of the model was thus consoli-dated into the mathmatical equations by which the necessary numerical computation couldbe solved by the method of finite difference. In the end-port glass making furnace regenerator, the measurements gained and thecomputation done under the condition interested are in good agreement, hence the calculatedresults of the thermal performance of the regenerators would provide a ready reference forthe designing and the operating work of any regenerators specified.
