一、点火技术本文讨论了35吨/时沸腾炉所采用的沸腾态油点火技术。该炉燃用Q_(DW)~V?1100大卡/公斤益阳石煤,点火主要环节为: (1)风量:从点火过程中的热平衡分析出发,说明风量是决定点火温升速度的主要因素。温升速度过低,即导致点火失败。故控制风量至为重要。合适的风量是每平方米床面为1500～2000标米~3/时。为适应此较小风量,对布风板结构和底料的制备均有一定要求,同时还应配备有效的风量计测系统。根
First, the ignition technology This article discusses the 35 tons / hour boiling furnace boiling oil ignition technology used. The furnace burning Q_ (DW) ~ V? 1100 kcal / kg Yiyang stone coal ignition main links: (1) air flow: starting from the ignition process of heat balance analysis shows that the air volume is the main factor that determines the ignition temperature rise speed . Temperature rise is too low, which led to ignition failure. Therefore, the control of air flow is important. The right amount of wind per square meter of bed is 1500 ~ 2000 standard meters ~ 3 / hour. In order to adapt to this smaller air volume, there are certain requirements for the structure of the air distribution plate and the preparation of the bottom material, and an effective air volume measurement system should also be equipped at the same time. root
