提高热风温度,我厂面临两大难题:一是高炉煤气热值低,既难以实现富化,也不可能很快实现助燃空气预热,因此拱顶温度低,升温速度慢;二是高炉煤气用户较多,热风炉煤气用量受到一定限制。因此,提高风温、节约煤气对我厂至关重要。自寻最优控制器既能提高风温,又能节约煤气,因此被我厂采用,具有很大的现实意义。 Increase hot air temperature, I plant is facing two major problems: First, low calorific value of blast furnace gas, it is difficult to achieve enrichment, it is impossible to quickly achieve combustion air preheating, so vault temperature is low, slow heating; second blast furnace gas Users are more, hot stove gas consumption subject to certain restrictions. Therefore, to improve air temperature and save gas is very important to our factory. Since seeking the best controller can not only improve the air temperature, but also save gas, so I plant adopted, with great practical significance.
