Every year, 400-500 explosions occur worldwide in storage and processing facilities for plant raw materials, including food production facilities.
⚡ According to DustEx Research Limited, storage bunkers had the highest percentage of combustible dust incidents in 2023, with 64 fires and 10 explosions, accounting for 38.7 per cent of all combustible dust incidents at facilities. This is a higher percentage than the 2017 and 2018 reports, which found that the highest percentage of incidents occurred on dust collection systems. In addition, of the known equipment incidents, storage silos had the highest number of injuries in 2023, with 13 injuries.
The hazard is related to the specifics of the technological process:
▪ the presence of a flammable dust-air mixture;
▪ occurrence of explosion initiation source in the tank due to self-heating and self-ignition of the bulk products;
▪ release of combustible gases during fermentation of raw materials due to high humidity.
Prolonged storage of self-heating products in containers leads to their spontaneous combustion. In this case, combustible gaseous products of thermo-oxidation reaction in dangerous concentrations: hydrogen, methane, carbon oxide enter the overhead and underwater spaces, as well as the rooms of the overhead and underhead floors.
The rules of operation of silos and hoppers prescribe to prevent dust accumulation, long-term storage of vegetable raw materials; control the temperature and humidity in the container. If explosion prevention is carried out, the probability of explosion is reduced, but it cannot be completely excluded. If the rules of operation are violated, it increases multiply.
