  • a combination of storage and drying takes place in the large ones Drying rooms in which ceramic workpieces (e.g. refractory blocks for Construction of float glass pools, porcelain or high voltage insulators) often over Weeks to be dried.
  • the heatable rooms mentioned as examples must be used to achieve a uniform temperature distribution targeted and even with the heated Gas flow. This is usually used accordingly dimensioned blowers.
  • the air in the Circulation using moving air fans that move air out of the room, circulating air called, suction and elsewhere - after heating and cleaning if necessary - feed again.
  • the high ones usually required Air volumes require the use of powerful fans, so that In order to save performance, the pressure losses in the air recirculation system are constructive must be minimized. This is done by using the flow cross sections for the Circulated air flows selected as large as possible and distributing units such as air baffles, Chokes etc. can be avoided.

  • the admixing gas consists of heated gas, it has a lower temperature than the heated gas.
  • the mixture of heated Gas and admixing gas are therefore correspondingly cooler than the pure heated gas.
  • the removal of the admixing gas from the one behind the fan warmed gas also has the advantages that, firstly, no separate gas must be provided and secondly the pressure of the - already existing - Blower for returning the admixing gas and mixing it with the heated gas is used. As a result, the existing systems and Procedure to be carried out change effort for the conversion to the method according to the invention minimized.
