Abstract

PURPOSE:To provide the subject method comprising retaining the temperature of water at the inlet of the cooling member system when teh evaporation cooling method is changed over to the forced water circulation method, thereby imparting no abrupt thermal influence to the shell to prevent the melting loss of the tuyere.
