Numerical simulation of the vented explosion process of premixed gas in the communicating vessel;

Experimental investigations of external second-explosion induced by vented explosion;

Based on the conversation equations for hydrodynamics and chemical reaction dynamics,by adopting the k-e turbulent model and the EBU-Arrhenius combustion model,the SIMPLE algorithm was used to investigate numerically the methane-air premixed gas vented explosion process in the two-dimensional space of the spherical vessel with a conduit for explosion venting.

A methane-air mixture explosion venting process is numerically investigated in terms of Euler equations coupled with the element chemical reactions.

These problems include high explosion venting rate of electrostatic precipitator, high equipment failure rate, poor performance of evaporative cooler nozzle, the production of high maintenance costs, large fluctuation of the dust contained in the flue gas and other issues.

The concept of explosion venting encompasses all measures used to open the originally closed vessels and equipment either briefly or permanently in a non-hazardous direction following an explosion and explosion venting technology describes one of the possible protective measures against the effect of explosions.

Study on Quenching of Dust Explosion Venting;

Pressure measurement inside and outside the vessel during venting explosions;

Analysis of large area explosion of water wall tube in SG-420/13.7-M417 boiler;

By analyzing the experiment of the draining duct,this paper puts forward the opinion that the draining duct can be added to the guide place of finished detonator,which can promptly drain off the wave produced by the explosion of detonator and greatly enhance the safe production.
