The articles are arranged in hanging fashion on a moveable arched cover over the upper shaft opening of the kiln. The kiln comprises a tunnel chamber having separating side walls opening outwardly into the flame zone in the region of the firing zone. There are also provided thin walled, fire resistant hollow blocks in said region. These hollow blocks are arranged so that they prevent relative movement to each other transversly of the furnace axis. Openings are provided in the blocks, burners are directed toward such openings. Hot gasses are removed in a composition below a cool air flow channel which is bounded by the upper tunnel chamber and opens thereto and a gap is provided for the inflow of outer air between the arched cover and the outer contour of the cool air flow channel.，下面是Tunnel kiln专利的具体信息内容。

权利要求
