    摘要: A fluid heating apparatus heats fluid in a passage to a target temperature. The fluid heating apparatus includes a fluid heating unit that heats the fluid, a fluid temperature measuring unit that measures a temperature of the fluid, and a pressure control unit that controls a pressure in the passage such that the pressure becomes equal to a target pressure. While the fluid in the passage is heated to the target temperature and when a temperature estimated from the thermal conductivity and specific heat is not increased, the pressure control unit increases the target pressure. According to a fluid heating method, when the fluid is heated by the fluid heating apparatus, the pressure control unit controls the pressure of the fluid such that the pressure becomes equal to or higher than a critical pressure.

    摘要: In a fuel lance by means of which fuels can be injected, via at least two separate passages, into a combustion chamber alternately or simultaneously at an injection location arranged substantially at the lance tip, reliable operation is achieved, without the risk of flashbacks and also without coking, by virtue of the fact that the fuel lance, in addition to fuel, also passes purge air to the injection location, and that the purge air, at the injection location, is routed between the two fuel systems, in such a manner that these systems are shielded from one another by the purge air.

    摘要: The invention relates to an apparatus for the thermal treatment of process exhaust gases containing pollutants, which can be used in particular for a very wide range of surface modification processes carried out under a vacuum. The intention is to achieve the object of thermally treating process exhaust gases containing pollutants in such a way that accumulations of particles on the inner wall of a combustion chamber and an undesirable adverse effect on the thermal conversion can be avoided with little outlay. In a combustion chamber of the apparatus according to the invention, at least one burner with a process exhaust gas feed is arranged at the top cover of the combustion chamber. Furthermore, there is a feed for washing liquid, which forms a film for the removal of particles on the inner wall of the combustion chamber, and a discharge for exhaust gas and washing liquid arranged at the base. The feed for the washing liquid is arranged immediately below the cover and is designed in such a way that a continuous film can form over the entire inner lateral surface of the combustion chamber exclusively under the force of gravity. Moreover, that part of the cover which faces into the interior of the combustion chamber and has the at least one burner should not be wetted by the washing liquid.
