Abstract
Filter boxes for ceramic foam filters in Aluminum casthouses are typically preheated by gas-fired systems, as they are faster and more versatile than existing electrical preheating solutions. The Drache Flow Heater is a next-generation electrical preheating system which has the efficiency of a gas-fired system, combined with the ease of use of an electrical system. In this paper, a brief introduction to the technology of the Flow Heater is given. A comparison is made between the Flow Heater, a gas-fired preheating system, and existing electrical heating solutions, showing the individual advantages of each system. Performance data for preheating ceramic foam filters with the Drache Flow Heater is shown. Furthermore, an outlook on the future development of the Flow Heater system is given.
