ABSTRACT:
The invention involves the generation of dry hot steam to be drawn into an oven cooking cavity where the steam is allowed to contact dough pieces on a baking plate in order to bake French bread with a glossy appearance and a hard crust, for example. In one embodiment, the cooking cavity is partitioned in the top thereof to form a steam generating chamber which receives therein a supply of water to convert it into hot steam with the heat from an upper gas burner located beneath the chamber. The upper gas burner and a lower gas burner located beneath the baking plate may be of forced combustion type and a perforated burner tube has provided along the length thereof a flame transmitting member which is divided into a plurality of segments mounted with a proper gap between two adjacent ones thereof to accommodate the thermal expansion of the segmented flame transmitting member and the tube per se. In another embodiment, the oven has a manually operable damper for selectively controlling the opening of an exhaust outlet in the rear of the oven leading to the cooking cavity. The damper is adjusted to control the amount of steam circulating in the cooking cavity depending upon the kind of foods to be baked and also in order to retain the heat of the oven to conserve fuel.
