A system (20) and method (100) using decentralized trace gas sensors (44a, 44b, 44c) and a central control element (46) to detect smoldering material in particulate material processing equipment (26) with continuous air flow (22, 24, 34). First and second sensors (44a, 44c) measure gas concentrations at an air inlet (22) and an air outlet (34), respectively. The control element (46) receives the measurements from the sensors (44a, 44c) simultaneously, considers the first and second concentrations simultaneously to determine an amount of gas being produced in the processing equipment (26), determines whether the amount of gas being produced exceeds a threshold value indicative of smoldering, and if so, activates an alarm. A user interface (48) allows a user to interact with the control element (46), including resetting the alarm, viewing current and stored sensor and system information, and initiating a test of the system by exposing the sensors (44a, 44b, 44c) to gas released from a gas reservoir (50a, 50b, 50c). |

1. A system for detecting a smoldering of a material in a processing equipment, the processing equipment having a first air inlet and an air outlet, the system comprising:
a plurality of sensors configured to measure concentrations of a trace gas, including a first sensor configured to measure a first concentration of the trace gas at the first air inlet, and a second sensor configured to measure a second concentration of the trace gas at the air outlet; an electronic control element configured to receive the measurements of the trace gas simultaneously from the plurality of sensors, consider the first concentration of the trace gas and the second concentration of the trace gas simultaneously to determine an amount of the trace gas being produced in the processing equipment, determine whether the amount of the trace gas being produced in the processing equipment exceeds a threshold value indicative of smoldering, and activate an alarm if the amount of the trace gas being produced in the processing equipment exceeds the threshold value; and a user interface configured to allow a user to interact with the electronic control element, including resetting the alarm. |
