    MODEL TO ASSESS ENERGY CONSUMPTION IN INDUSTRIAL LUMBER KILNS

    At equilibrium, the heat power supplied to the kiln is equal to the heat losses, thus a generic heat transfer coefficient (including both thermal insulation and air leakage) was calculated with a definition similar to equation 12. Then, warm-up heat is equal to the total energy supplied to the kiln minus the integral of the heat losses
