Long-term accumulation of coal in coal yard will spontaneously ignite due to oxidation, resulting in a large amount of coal burned in vain, which seriously threatens the life and property safety of nearby facilities and operators. However, the coal yards of most domestic power plants generally need to storethreeThe normal consumption of more than one month can ensure the uninterrupted operation of the generator set. Due to the limitation of coal storage environment and long storage time, coal piles often spontaneously ignite, even at several places at the same time, which causes huge economic losses and serious environmental pollution. Therefore, it is very important to find the spontaneous combustion of coal piles in time and prevent the expansion of spontaneous combustion range.

With the development of modern high-tech, people are constantly looking for better methods to detect spontaneous combustion of coal piles at an early stage, such as flame smoke detection, light characteristic detection and temperature detection. As an advanced high-tech monitoring method, infrared thermal imaging temperature monitoring can be applied to the monitoring and early warning of spontaneous combustion in coal yard and play an important role because of its irreplaceable advantages of using temperature to image.
