Temperature Monitoring and Early Warning for Coal Stack Based on Optical Fiber Sensor |
| |
Abstract: | Spontaneous combustion of coal stack will cause huge economic losses and serious environmental pollution.A distributed fiber optic temperature monitoring system is designed for coal stack based on Raman scattering principle,consisting of three parts of the host of temperature,the sensing fiber and temperature monitoring software.With high sensitivity,good reliability,and not affected by electromagnetic interference,it can be used for the monitoring of the temperature of the coals throughout,and issued a early warning to avoid the occurrence of the phenomenon of spontaneous combustion. |
