Research on combustion and explosion characteristics of mixed feed dust
In order to explore the combustion and explosion characteristics of mixed feed dust with different proportions,a 20 L spherical explosion test system and a Hartmann tube were used to test the minimum ignition energy(MIE),minimum explo-sive concentration of dust cloud(MEC),maximum explosive pressure(Pex)and explosion index(Kst)of corn powder,corn straw powder and three samples mixed with different proportions.The pyrolysis characteristics of mixed feed with different pro-portions were analyzed and compared by the synchronous thermal analyzer.The results show that when the mixing proportion is 3∶2,the weight loss rate is higher,and more heat is released during the pyrolysis process.When the mixing proportion is 1∶1,the MIE and MEC values are higher,the Pex value is the largest,and the hazard and destructive power are greater.The research results can provide reference for the explosion-proof of mixed feed processing.
