Abstract
A truck for use in a tunnel kiln is disclosed. The tunnel kiln is used for firing shaped bodies by heating them with use of a plurality of combustion burners provided on sides inside the tunnel kiln. The truck comprises supports. Among them, at least supports with which a combustion stream from the combustion burners directly contacts have a streamlined shape with respect to the combustion stream. By so constructing, turbulence of the combustion stream can be minimized to make temperature distribution more uniform inside the kiln.
