Description

technical field [0001] The invention relates to a test device, in particular to a multiple safety and energy-saving fire test furnace. Background technique [0002] When mentioning an explosion, people always naturally think of the earth-shattering bang when explosives or combustible gas and oxygen (or air) explode. As everyone knows, the floating dust suspended in the air will also cause a powerful explosion. [0003] Dust explosion accidents are common at home and abroad. In 1921, a dust explosion occurred on a large grain elevator in Chicago, USA. The explosive force lifted 40 warehouses, each containing about 300,000 tons of grain, from the base and moved them by 152.4 mm. As a result, 6 people were killed and 1 injured, and economic losses up to $4 million. In 1942, the world's largest coal dust explosion occurred in Benxi Coal Mine in my country, killing 1549 people and seriously injuring 246 people. On August 2, 2014, a particularly serious aluminum dust explosion...
