A new model of a 1-D distributed-parameter tunnel kiln has been proposed in the form of an integral equation. Its kernel function characterizing the mixing and boundary conditions has been assumed to consist of a finite number of elementary kernel functions of its subsystems and the parameters of this kernel function are directly measurable on a real kiln. According to industrial need, a simple optimization procedure is proposed for minimizing the specific energy with respect to unit product mass in the steady-state of the kiln. Technological requirements are given in the form of inequalities for the temperature and temperature gradient of the product in the kiln. As a result 5-8 % of usually used energy has been saved.
