Firing ceramics that contain organic binders poses a unique safety consideration. When heated, organic binders release combustible vapors. Under some conditions, concentrations may reach flammable or explosive levels during binder burn-out.
Monitoring combustible gas concentrations can provide a layer of safety. In addition, knowing how the combustible gas concentration varies over time, and the peak it reaches, is useful process data. It can increase understanding of how the firing proceeds over time, and it can inform decisions about the safe and efficient loading of the kiln. It can therefore be desirable to monitor combustible gas concentrations rather than, or in addition to, oxygen. Before measurements can be made, however, some important hurdles must be cleared.
