- Abstract
- Fire detectors and their suitability to peat boiler plants is considered. The main interest is concentrated on the methods applicable to detection of smouldering fires. The description of fire detection of smouldering fires. The description of fire detection methods is based on the literature and brochure information of the devices. In addition fire detection and extinguishing systems of three peat boiler plants are described briefly. The conventional smoke detectors are not applicable to detection of smouldering fires in dusty environments. IR spark and flame detectors have been developed intensively during the last years and these are also available to detection of smouldering fires. The improvement of detectors has decreased their sensitivity to false alarms. The present IR detectors are most applicable to spark and fire warning in pneumatic dust coveyor tubes and in dust separators, but these detectors have been used also in association with belt conveyors at peat heating plants.
