Experimental study of combination of metal wire mesh and foam ceramic for suppressing the gas explosion.

By using self-designed gas explosion experimental pipe with the section of 30 cm x 30 cm, the authors carried out the experimental studies for the explosion suppression effects according to different parameters of metal wire mesh and foam ceramic materials and their combination. With the materials' characteristics, the function mechanism for the explosion suppression of the combination was analyzed. The results show that the performance of some parameters combined materials of wire mesh and the foam ceramic is better than that separate ones in the respect of pressure reduction and flame temperature and the damage of the explosion suppression materials is reduced obviously. The combined material can exert the advantages of original ones and avoid their disadvantages. The combined material can enhance the explosion suppression effects and reduce the damage of the materials. [ABSTRACT FROM AUTHOR]
