Xiaohongmen energy storage spontaneous combustion

What is spontaneous combustion of coal & biomass fuel?

Spontaneous combustion often occurs when carbonaceous materials are stored for a long time. Up to now, domestic and foreign scholars have done a lot of research on the spontaneous combustion mechanism of coal and biomass fuel, monitoring methods and prevention measures, and achieved fruitful results.

Why is spontaneous combustion monitoring important?

This is of great innovative significance for spontaneous combustion monitoring and prevention of coal and biomass under silo conditions. Spontaneous combustion often occurs when carbonaceous materials are stored for a long time.

Can spontaneous combustion monitoring and fire prevention be achieved in coal storage silos?

At present, very fruitful results have been achieved in coal spontaneous combustion monitoring and fire prevention in mine, but the spontaneous combustion research around coal storage silos and biomass silos is insufficient, and the spontaneous combustion monitoring and fire prevention technology for them is relatively backward.

Can a spontaneous combustion method be used for coal spontaneous combustion monitoring?

The spontaneous combustion characteristics of biomass are worthy of reference for coal spontaneous combustion monitoring, but the structure of the two is different, and the spontaneous combustion monitoring method suitable for one fuel cannot be directly transferred to the other fuel.

What is the characteristic of oxidation self-heating in coal storage silo?

As shown in Fig. 1. Fig. 1. Coal storage silo. Coal has the characteristic of oxidation self-heating, because the silo is not completely closed structure, and the “chimney effect” in the coal storage silo will promote the oxidation heat release of coal.

How to prevent spontaneous combustion of coal?

At present, in mine mining and open pit coal storage, two methods of reducing temperature and isolating oxygen are often used to prevent spontaneous combustion, such as covering coal with cement slurry, spraying retarder, and injecting foam [ 67, 69, , , ], as shown in Fig. 11. Fig. 11.
