Function: always control the concentration of the fuel, do not let it reach the "explosion limit"". Once the explosion does not crowd. In 2015, China's Taiwan District of New Taipei city amusement park occurrence of dust explosion accidents caused many casualties, scary. The amusement park is hell, because people in the activity of spraying corn flour mixed with air after the formation of a certain concentration ratio, the spark explosion immediately met.
"The explosion limit" means that it is the concentration range that can lead to the explosion ". Flammable substances and air must be uniformly mixed in the explosion limits, in case of fire explosion; the lower limit of the explosion does not explode nor fire; in the higher than the explosion will not explode, but can burn.
Different material explosion limits are not the same. The incident is very sudden, dust explosion is more easy to ignore, such as aluminum, zinc etc.. Place all kinds of plastic powder, wheat flour, milk powder, coal dust, fiber production and processing plants are prone to dust explosion, so to control these places the combustible concentration, ensure safety in production. Explosion suppression need to pay attention to the explosion limit of the fuel, because in case of improper rescue operation, may cause a number of explosions caused by a large number of casualties. Encounter such a explosion, remember do not onlookers!
