Operation of injector devices in a tunnel kiln at the Nikitov dolomite combine

Conclusions The injection coefficient of injector devices of a typical high-temperature tunnel kiln designed by the All-Union Institute of Refractories changes from 4 to 9, depending on the working conditions. The main factor affecting the injection coefficient is the pressure behind the injector mixer.Control of the injection coefficient by the thermal balance method gives completely satisfactory results. The thermal loss of the injector device is determined with the coefficient being approximately equal to 1.15.Translated from Ogneupory, No. 5, pp. 11–15, May, 1967.
