The energy consumption of a given facility is always of interest and, when energy resources are limited or expensive, often the objective of intensive investigation. The efficiency of dryers and kilns is evaluated on the basis of energy balances. Energy balances enable statements concerning:
› energy conservation potentials
› comparison of the energy efficiency of different operating conditions
› the technical and financial assessment of newbuild projects (insulation of dryer walls, refractory superstructures for kiln cars)
Similar to double-entry bookkeeping, the...
