Numerical simulation study on optimization of ventilation airflow organization of a raw coal bunker

For the problem of gas accumulation in product bunker a company’s coal processing plant, three different ventilation schemes are proposed. The first one opens rectangular air inlet louvers on wall and adds fans top for exhaust; second sets six windows evenly natural ventilation; third sends to interior through small holes distributed pipes exhaust ports wall. Finally, effect management scheme is simulated analyzed numerical simulation. applicable raw bunkers with storage heights, provides technical reference plants.
