In the apparatus shown in Fig. 1, the air to be heated passes through a pipe C to a heating-box D, provided with baffles d', d<2> and with exit tubes E fitted with nozzles e for insertion into the bungholes of the casks, for which stands e<1> surrounding the nozzles are provided. The air is heated by furnaces B, the gases from which surround the box D and escape through the flue K. In the apparatus shown in Fig. 3, the lining- composition enclosed in a tank L is heated by steam, which enters by a pipe N to a surrounding tank M partially filled with water, the compositioh being ejected through a nozzle S to the cask resting on a stand T by a force pump o.
