Patent number: 7666367Abstract: The invention relates to a device equipped with a burner for combusting a fuel/oxidant mixture inside a combustion chamber in which a material (3, 3?, 3?, 3??) is provided that endures a maximum temperature. The inventive device also comprises one or more supply lines (25, 26) for the fuel as well as for the oxidant which are provided for supplying the same into the combustion chamber. The inventive device is characterized in that it is designed for carrying out a combustion with a combustion temperature of the fuel/oxidant mixture that exceeds the maximum temperature. The device is designed in such a way that at least one additional supply line (30) is provided via which an additional gas having, in particular, a low calorific value can be supplied to the combustion chamber. Said additional gas enables the temperature during combustion to be lowered to a value that is less than the maximum temperature.Type: GrantFiled: July 3, 2000Date of Patent: February 23, 2010Assignee: SGL Carbon AGInventors: Franz Durst, Jürgen Künzel

Publication number: 20040175323Abstract: A process for preparing hydrogen chloride includes reacting chlorine with water vapor in an endothermic reaction with heat being supplied in a first process step to give a mixture of hydrogen chloride and oxygen. Then in a second process step, chlorine that has not been reacted in the first process step is converted into hydrogen chloride in an exothermic reaction by the addition of a reducing agent and oxygen formed in the first process step is bound by the reducing agent. An apparatus has first and second reactors for carrying out the process.Type: ApplicationFiled: March 5, 2004Publication date: September 9, 2004Inventors: Marcus Franz, Jurgen Kunzel

Patent number: 4651655Abstract: Dissolving salt encrustations which are deposited by exceeding the saturation limit from a gas saturated with water vapor on the heat exchanging surfaces of a heat exchanger, by passing the gas through a heat exchanger subdivided into several sections. The predominant part of the sections is subjected to a hot fluid heating the gas saturated with water vapor and the smaller part of the sections to a cold fluid for cooling the gas below the dew point. The salt crust is dissolved in the cooled sections by the separated condensation water and the salt solution is drained from the heat exchanger. After the salt crust is removed, the cooled sections are subjected to the hot fluid and parts of the heated sections to the cold fluid.Type: GrantFiled: March 4, 1986Date of Patent: March 24, 1987Assignee: Sigri GmbHInventor: Jurgen Kunzel
