Abstract: A cooking oven includes a cooking cavity with an opening for enabling food items to be moved into and out of the cooking cavity. A combustion area is located below the cooking cavity and a combustion gas flow space includes paths along left and right external sides of the cooking cavity. A burner is disposed in the combustion area and has a left burner segment disposed left of a centerline of the cooking cavity and a right burner segment disposed right of the centerline of the cooking cavity. A baffle arrangement is located in the combustion area. The baffle arrangement includes an upper baffle that has a low point substantially aligned with the centerline, and a lower baffle wall extending downward from the low point and between the left burner segment and the right burner segment.

Abstract: A method and furnace assembly for treating solid refuse. The refuse comprises both recoverable materials useful either in cement or in construction and contaminants. The contaminants have a vaporization temperature lower than the vaporization or sublimation temperatures of the recoverable materials. The furnace assembly comprises a resource recovery furnace connected to a cement manufacturing furnace. According to the method, the refuse is transferred through a resource recovery furnace. Inside the resource recovery furnace the refuse is separated into vaporized contaminants and recoverable materials. Gas carrying the vaporized contaminants is transferred to the cement manufacturing furnace and used as an energy source. The recoverable materials are used in the cement manufacturing furnace as a constituent for making cement.
