Thermal Efficiency Of Tunnel Kiln

Thermal Efficiency Of Tunnel Kiln. An in-depth thermodynamic analysis of modern high-temperature tunnel kilns showed that the principal exergy losses in the kilns are due to the irreversibility of the kiln processes and the imperfect design of the roof. In the 0.75-m-high kiln the internal exergy losses can be reduced by shortening the heating
