COMBUSTION CONTROL WITH FLAME SIGNALS FOR PARTIAL OXIDATION PROCESS

摘要

The SCOT-System as lambda sensor system for air-rich mixtures with lambda > 1 has proven to be reliable in different applications. This SCOT-System is also usable for controlling fuel-rich mixtures with lambda < 1, and the ionisation probe as an air ratio sensor can control a partial oxidation process. For dynamic fuel cell operations it is necessary to generate different amounts of hydrogen-rich synthesis gas as quick as possible. The system automatically controls the combustion and compensates different gas compositions.rnFurthermore, this presentation is to demonstrate how to integrate a SOFC fuel cell operating with a partial oxidation combuster in a residential condensing boiled system. With this application it is possible to decentrally produce heat and electric power with a small scaled power module.
