Abstract: The system described herein relates to a baking oven having a baking chamber which is provided with an outlet opening leading to a flue. Air is able to escape from the baking chamber through the outlet opening. A fresh air opening with a motor-adjustable flow cross section is provided between the baking chamber and the surroundings. The system adjusts the pressure conditions within the baking chamber optimally throughout the baking operation. A pressure sensor measures pressure in the baking chamber and passes the measurement signals to a control unit which controls the adjustable flow cross section of the fresh air opening on the basis of the measurement signals from the pressure sensor.

Abstract: A steam generator for an oven, includes at least one heat transfer element and at least one water conduit which carries water to the heat transfer element. The system optimizes the targeted introduction of steam into a defined space and the removal thereof from the space. This is achieved by means of at least one pressure increasing device which increases the water pressure, such as e.g. a compressed air line through which compressed air is fed to the water.
