Choosing burners for tunnel kilns

Conclusions Double-duct burners fitted to tunnel kilns have proved themselves. Subsequently, it will be necessary to improve the design of burners and to carry out research into the most rational economic combustion of natural gas.Hot-air injection into burners is undesirable in tunnel kilns heated with natural gas and used for firing chamotte and dinas products.A discussion.Translated from Ogneupory, No. 5, pp. 11–13, May, 1968.

Convective heat exchange in tunnel kilns

Conclusions In calculating the coefficients of heat transfer by convection in tunnel kilns for the longitudinal surfaces of the setting with a latticed column structure Eq. (1) is recommended, for the longitudinal surfaces of the setting with solid columns Eq. (9); and for transverse surfaces in the setting Eq. (14). The resulting coefficients of heat transfer can be made more accurate by multiplying them by the value , determined from Eq. (2).Translated from Ogneupory, No. 3, pp. 20–27, March, 1972.
