This standard specifies the basic requirements of explosion prevention design for coal conveying, storage and pulverized coal preparation of coal-fired power plant, as well as such design for relevant flue, air duct and dust ignition.
This standard is applicable to coal and pulverized coal preparation system of coal-fired power plant, as well as explosion and ignition of pulverized coal cloud in enclosure (such as raw coal bunker, pulverized coal bin, coarse and fine pulverized coal separator as well as cylindrical silo etc.). For coal-fired power plant using multi-fuel ignition of coal and fuel oil or that of coal and fuel gas, it shall comply with this standard for contents related to coal.
This standard is not applicable to enclosure that produces extremely large internal pressure due to external flame or being exposed to other ignition source. If there are explosion prevention requirements of boiler furnace and boiler ignition system, it is not applicable to detonation and unconditional explosion and ignition.
