Abstract: The invention relates to a condenser tumble dryer with a drum for articles to be dried, a drive motor for the drum, a process air duct, a process air blower, a heating and cooling system for the process air, a temperature sensor and a control device. The temperature sensor is an infrared telescope and is arranged to simultaneously measure heat radiation from at least two components of the condenser tumble dryer which are to be monitored. The invention also relates to a method for operating a condenser tumble dryer of said type.

Abstract: The invention relates to a reformer (10) for converting fuel (32) and oxidant (34) into a reformate (30), comprising a catalytic device (12) through which the fuel (32) and oxidant (34) can flow via a catalyst inlet (36), and a heat exchanger (14). According to the invention, the heat exchanger (14) is in heat-exchanging communication with least one segment of the catalytic device (12) adjacent to the catalyst inlet (36). The invention further relates to a method for operating such a reformer (10).

Abstract: The invention relates to a reformer (10) comprising a first media feeder portion (12) for receiving a supply of fuel (14) and oxidant (16), following the first media feeder portion an oxidation zone (18) in which the media supplied to the first media feeder portion react at least in part into flue gas (20), a second media feeder portion (22) for receiving at least a supply of fuel (24), a mixture formation zone following the oxidation zone (18) and the second media feeder portion and in which a fuel/flue gas mixture (28) can be generated, and following the mixture formation zone (26) a reforming zone in which the fuel/flue gas mixture (28) is catalytically reformable. In accordance with the invention it is provided for that the volume of the mixture formation zone is in the range of 20 to 90 cm3.
