Definitions

  • the invention relates to a device for heat transfer, with at least one heat transfer member, which is alternately flowed through by a first, hot fluid and a second fluid. Furthermore, the invention relates to an exhaust gas purification device and a method for transferring heat of a first fluid to a second fluid.
  • Devices for heat transfer of the aforementioned type are known from the prior art. They are often used in emission control systems in order to regenerate the heat generated during a combustion process and to recycle it to the combustion process.
  • the exhaust gas produced during combustion is passed through the heat transfer member in a first phase. Once this is heated, the supply of hot exhaust gas is turned off and flows through the heat transfer member instead with a cold fluid, which is on its way into the combustion chamber. This is heated up by which less external energy, for example in the form of fuel, has to be fed into the combustion chamber in order to reach a certain temperature.
  • the heat generated during this heat transfer process can not be used elsewhere. Thus, only a regenerative use of this heat within the emission control system is possible.

  • a continuous stream of the first hot fluid may be passed sequentially through the devices or heat transfer members and an equally continuous stream of vaporized second fluid may be withdrawn from the apparatus. Due to the production of the heat transfer member made of ceramic, this is particularly temperature change resistant.

  • an enclosure of the heat transfer member provided by a container so for example the insulation on the outside of the heat transfer member and then the container may be provided.
