摘要： A cooking oven is made with a flat base of refractory material and a dome of refractory material forming an enclosure in which solid fuel is burned while resting directly on the base and food is also cooked directly on the base. An opening is provided in the dome wall through which fuel and food can be separately inserted within the oven. Only a relatively small part of the dome is removed to form the opening, which extends only part way up the full height of the dome. A flue is located just outside the opening so that combustion products from the fuel pass generally horizontally through the enclosed space and out the opening and up the flue. A closure is provided to shut the opening to limit the escape of heat. The dome is made by casting hemispherical sectors of refractory material and assembling the sectors into a dome on the base. The sectors are formed with interlocking edges to help hold them together and the entire dome can be enclosed within an insulated chamber..

摘要翻译： 烹饪炉由耐火材料的平坦基底和耐火材料的圆顶制成，形成封闭物，固体燃料在其中直接搁在基座上而被燃烧，食物也直接在基部上烹饪。 在圆顶壁上设有一个开口，燃料和食物可以通过该开口分开插入烤箱内。 只有穹顶的相对较小的部分被去除以形成开口，该开口仅在圆顶的整个高度上部分地延伸。 烟道位于开口的正下方，使得来自燃料的燃烧产物大致水平地穿过封闭的空间，并从出口向上通过烟道。 提供封闭件以封闭开口以限制热量逸出。 圆顶通过铸造半球形耐火材料部分制成，并将这些扇区组装成基座上的圆顶。 这些扇区形成有互锁边缘，以帮助将它们保持在一起，并且整个圆顶可以封闭在绝缘室内。
