Abstract
In a full-size large steel plant, we analyzed the temperature distribution, the decline rate of dust and the smoke effect in two cases. The results showed that: natural draft reduced the sinking rate from 0.43 cm/s to 0.35 cm/s, the horizontal spread speed was reduced from 38.87 cm/s down to 30.99 cm/s in the plant; The highest temperature of workshop roof reduced from 76 °C to 60 °C; The layer height rose up from 3 m to 5 m, which made a greater affect on the visibility and it was more helpful for personnel evacuation and fire fighting and rescue activities. From the fire temperature and visibility control perspective, experiment proved that the affect of natural draft is good for the large steel plant.
