Powder deposits in a milk powder plant may start a fire. Once milk powder is smouldering, it produces a significant amount of carbon monoxide. Previous research showed that this increase of CO can be detected by a sensitive CO analyser. Based on this principle, NIZO developed a fire detection system, consisting of an air sampling and air sample preparation unit and a sensitive CO analyser. The system was tested on an industrial drying plant for a period of four months. The detection system operated without any malfunction. Little maintenance was required. CO emission sources in the neighbourhood of the drying plant may interfere. The system can compensate for this. Recommendations are given for a proper installation and maintenance of the system.
