HYDROGEN MEASURING PROBE FOR COAL-GASIFICATION PROCESSES

In the framework of the European R&D program on non-nuclear energy (JO ULE I) a research project started in 1990, aiming at in-situ analysis of product gas produced by coal gasifiers. Our contribution in the pro ject deals with the development of solid electrolyte based electrochem ical sensors. In this paper the design of the hydrogen measuring probe is presented together with the first emf-measurements in an Ar/H-2 at mosphere and in a simulated coal gasification atmosphere, while the la test results obtained in a real gasifier are discussed as well.
