Verfahren zur Vermeidung einer Rückzündung in einem einen Reaktionsraum anströmenden Gemisch und Reaktor zur Durchführung des Verfahrens

摘要

A method for preventing flashback in a reaction chamber that includes providing a mixture of educts flowing through a mixture distribution zone and into the reaction chamber. The mixture distribution zone has an inlet opening and a variable flow cross-section between the inlet opening and the reaction chamber. The method also includes combusting the mixture in the reaction chamber at a combustion rate, and varying the flow cross-section as a function of a volume of the mixture so as to affect a flow rate of the mixture into the reaction chamber such that the flow rate is greater than the combustion rate. In addition, a reactor that includes, an inlet opening for receiving a mixture of educts, a mixture distribution zone disposed downstream of the inlet opening and having a variable flow cross-section, a reaction chamber disposed downstream of the mixture distribution zone, and a regulation device disposed in the mixture distribution zone for varying the flow cross section.
