A study of the design of coal preparation plant firefighting systems

For facilitating rational deployment of firefighting facilities by design workers in design of coal preparation plant, and providing a highly secured plant area fire protection, a summation of the relevant norms and regulations is presented. Following an introduction, in particular, to the indoor and outdoor fire hydrants′ water supply systems, fire water curtain systems, automated water cannons′ water supply systems, layout of fire extinguishers and gas fire extinguishing systems, a detailed analysis is made on the water consumption of each fire water supply system and the duration of fire hazard calculated according to standard-specified figures. It is pointed out that the ultimate effective volume of the water pond of a coal preparation plant should be determined by the sum-total of the maximum volume of the water that can be consumed by both indoor and outdoor firefighting apparatuses of the plant′s largest building or structure plus the total water consumption in case the water curtain systems at the same floor are activated simultaneously. A comparison is also made of the firefighting systems suitable for use at different locations of a plant. It is finally proposed that rational and effective firefighting apparatuses should be selected for use according to the property and industrial use of each building or structure of a coal preparation plant for ensuring fire safety.
