As a heating device, the use of coal fired hot blast stove is also cyclical. Every year in the cold season, when the equipment is fully functional, it will go to sleep when the chill goes away. So what should we pay attention to when we start using hot stove every year? 1.在每一次休眠过后第一次使用的时候，我们都应该对燃烧室以及净化室等高温区域进行耐高温防护措施，主要是耐火砖与耐火泥。在初次使用时，炉膛的温度不宜上升过高过快，以免耐火材料的表面出现裂纹甚至发生崩裂的情况。
1. When we use it for the first time after each dormancy, we should take high temperature protection measures for high temperature areas such as combustion chamber and purification chamber, mainly refractory bricks and refractory mud. In the initial use, the furnace temperature should not rise too high or too fast to avoid cracks or even cracks on the surface of refractories.
2. there is a difference between the use of coal for the first time and the furnace that has been used for a period of time. For the first time, it is better to use some good quality coal. Not only to improve the efficiency of coal combustion, it is more important to choose the right coal. After calculation, we found that the coal with a diameter of 50-60mm is the best to burn in a coal-fired hot blast stove. For common fixed grate stoves, all kinds of bituminous coal, anthracite and lignite are available.
3. For the treatment of flue gas, if the flue gas is not used for a long time, there may be some problems in the treatment of flue gas. The general recommendation is wet desulphurization, which is also the mainstream method in the industry. In addition, we use the water film dust collector for flue gas dedusting.
