A horizontal coke oven has a floor with an upper layer (11a) and a lower layer (11b), each made of firebrick. The layers are made of the same or different types of material. The top layer is made of solid material. The lower layer incorporates a series of channels, gaps or cracks open to the ambient air. The upper surface of the top layer is flat. The downward-facing profile of the lower layer is domed. The thickness of the open channels is determined in accordance with the thickness of the main sidewalls.
