To avoid drastic changes in the temperature of hot blast stove, combustion adjustment methods 1) maintain a certain thickness of material layer when the load is stable, so that the combustion on hot blast stove grate can be stable; 2) avoid too low buffer material level, in operation, each feeding line must maintain the material level of the first two buffer boxes. The material level of the last buffer box fluctuates at 50% material level. This can maintain stable seeding and ultimately achieve stable combustion. 5. 热风炉观火孔的改进方法
5. improvement method of fire hole in hot blast stove
At present, the sight of the fire viewing hole of hot blast stove is not good enough to observe the thickness of charging layer and the detailed combustion situation of the grate. It is suggested that the larger fire viewing mirror be replaced. At the same time, the inside of the fire hole should be inclined upward and downward, and should be transformed into a horn mouth, so that the vision is wider, which is conducive to seeing the combustion of fuel on the grate. It is easy to open the outside of the fire observation hole. When the hot blast stove is running, the ash accumulated on the side of the fire observation hole can be sucked in. Otherwise, too much ash will be accumulated and the combustion situation on the grate can not be seen clearly.
6. It is strictly forbidden to mix plastic products (especially plastic film and plastic bags) into fuel to avoid plastics as far as possible. Because plastics contain a large amount of chlorine, when plastics are mixed in fuel, a large amount of hydrogen chloride may be produced, which corrodes the heating surface of water wall and the heating surface of tail flue.
