The results obtained show that airflow reversal of declensional ventilation is catastrophic and the reversal may occur even in higher quantity of ventilation airflow.
In large space building,several environment actors disadapt current fire detectors in early-stage fire detecting,such as width and scope of space,velocity of airflow,dust,temperature and humidity.
An investigation on dusted airflow distribution in gas chamber of multicyclone has been carried out by using the principle that the resistance of dusted airflow in it would keep equilibrium.
