Explosion protection for equipment in the wood slicing area of paper mills
Thread Content
Could you please tell me what the explosion-proof standards are for the equipment used in the wood chopping area of paper mills? What are the explosion-proof rating standards, and what are the relevant explosion-proof requirements?
The ignition temperature of wood is around 225°C, while that of coal is about 330°C. The minimum explosive concentration for coal is 60 g/m3, and the same value applies to wood powder as well. Based on these figures, it seems that the explosion-proof requirements for equipment used in processing and transporting wood can be set at the same level as those for equipment used with coal. However, according to statistical data, the likelihood of dust explosions involving wood powder is 30% to 500% higher than that involving coal powder. Therefore, the explosion-proof standards required for equipment used in processing and transporting wood should be higher than those for coal-related equipment. I have tried to find relevant domestic standards, but was unable to locate any. Relevant requirements can be found in ANSI-2004 \"Fire Protection and Explosion Prevention for Wood Processing and Processing Facilities\" or ANSI-2007 \"Fire Protection and Explosion Prevention for Wood Processing and Processing Facilities\". Does anyone here have such information?
