Abstract: A cleaning apparatus includes at least a holder, a lance with a fluid distributing device, a drive unit for a translatory movement of the lance in the holder, a first fluid conducting system with a first feed, a first return and at least one first flow path proceeding from the first feed toward the first return for cooling the cleaning apparatus, and a second fluid conducting system with a second feed and at least one second flow path proceeding from the second feed toward the fluid distributing device.

Abstract: Techniques relate to a cleaning device for an interior of a thermal power plant carrying flue gases, especially a so-called soot blower. The cleaning device includes at least one rigid lance having a base and a lance add-on part which includes at least one nozzle, the lance add-on part being detachably connected to the base. At least the lance add-on part includes at least one sensor for measuring an environment parameter. The techniques further relate to a method for installing such a cleaning device and to a cleaning and monitoring method for defined areas of the interior of the thermal power plant.

Abstract: A cleaning device for a combustion boiler, comprising a high-temperature-resistant cleaning hose for feeding a cleaning medium into the combustion boiler, a hose reel which can be rotated about a first axis of rotation, wherein the cleaning hose can be wound at least partially in said reel, and wherein the hose reel comprises an opening through which the cleaning hose can be guided during winding or unwinding parallel to the first axis of rotation.

Abstract: A measuring device for a heat exchanger includes a pressure pipe arrangement that is spaced using webs and that has a heating side and an isolation side and that is implemented with at least one heat flow sensor. A heat flow sensor is arranged on the heating side in such a way that at least two temperatures T1 and T2 and the temperature difference thereof can be detected there, and additionally at least one temperature sensor for measuring a temperature T3 is arranged on the isolation side and at a distance to the heat flow sensor.
