Abstract: A method for adjusting or controlling the temperature of water released for product pasteurization, by taking into consideration the heat transfer into the products for the control of the water temperature. Further, a method for adjusting or controlling the water temperature for the water released for product pasteurization in several superimposed decks, by taking into consideration the water temperature in at least one deck located below the upper deck for the control of the water temperature. Also, corresponding pasteurization tunnels as well as a pasteurization tunnel with at least three superimposed decks, where the water for at least three decks is released to the products in the uppermost deck.

Abstract: A method of controlling a turbine, in particular a wind turbine, which improves the energy production from the turbine while ensuring that no damage or structural overload occurs. The turbine may be operated at or near the Cp,max trajectory at rotational speeds which exceed the nominal rotational speed of the rotor of the turbine. This provides an improved energy production.
