| 摘 要： | 在炼油生产中,由于加热炉负荷和工况的变化,经常会调整炉温以及出现炉温偏差,为了满足工艺生产的要求,则需要对燃料进行调节。在一般调节过程中,由于温度响应比较慢,且不易稳定。采用交叉限幅控制,可以使燃料和空气达到动态过程的空燃比基本协调一致,从而减少损失,节省燃料。

| Abstract: | In the oil refining the production because of heat stove burden and work condition of variety, usually adjust stove and appear a heat of deviation, for the sake of satisfy craft produce of request, then need to carry on regulate to the fuel.In generally regulate the process because of the temperature respond to slower, and not easy stability.Adoption cross only for, can make fuel and air attain dynamic state process of empty Ran ratio basic moderate consistent, thus decrease loss, economical fuel. |
