In plants where material is processed, the detection of smoldering fires is a big challenge: Optical detection by Infra Red Sensors or smoke detectors is rendered difficult due to dust clouds inside the equipment. Temperature sensors deliver only information on their local environment and cannot detect hot spots over a certain distance.
The detection of decomposition or smoldering gas, in particular Carbon Monoxide (CO), may be a solution to this issue. CO-Monitoring is already well-established in many drying processes. It might also be the solution for the protection of your plant and employees.
