热风炉次使用要注意哪些问题?

  热风炉作为加热设备,其使用也是周期性的。每年,在寒冷的季节,当设备处于佳状态时,它就进入休眠状态。那么,当我们每年开始使用它的时候,我们应该注意什么呢?
  Hot blast stove is used periodically as heating equipment. Every year, in the cold season, when the equipment is in its best state, it goes to sleep. So, when we start using it every year, what should we pay attention to?
  1. 每次休眠后次使用时,应对燃烧室、净化室等高温区域采取高温防护措施,主要包括耐火砖、耐火粘土等。在初次使用时,炉温不宜升得太高太快,以免耐火材料表面开裂甚至开裂。
  1. When used for the first time after each dormancy, high temperature protection measures should be taken in high temperature areas such as combustion chamber and purification chamber, mainly including refractory bricks and refractory clay. When used for the first time, the furnace temperature should not rise too high and too fast to avoid cracking or even cracking of refractory surface.
  次使用的炉子和已经使用了一段时间的炉子在煤的使用上是不同的。次使用优质煤比较好。不仅要提高煤的燃烧效率,更重要的是选择合适的煤。通过计算发现,粒度为50-60mm的煤在燃煤热风炉中燃烧效果好。普通固定炉排可选用各种烟煤、无烟煤和褐煤。
  The first stove and the one that has been used for some time are different in the use of coal. It is better to use high quality coal for the first time. It is not only necessary to improve the combustion efficiency of coal, but also important to select suitable coal. Through calculation, it is found that coal with particle size of 50-60 mm has the best combustion effect in coal-fired hot blast stove. Various bituminous coal, anthracite and lignite can be selected for ordinary fixed grate.
  3.对于烟囱的处理,如果长期不使用,很可能在烟气的处理中出现一些问题。一般建议采用湿法脱硫,方便使用,这也是工业上的主流方法。此外,对于烟气除尘方法,我们采用了水膜除尘器。
  3. For the treatment of chimneys, if they are not used for a long time, there may be some problems in the treatment of flue gas. Wet desulfurization is generally recommended for easy use, which is also the mainstream method in industry. In addition, for the flue gas dedusting method, we use water film deduster.
  煤粉热风炉与燃气热风炉的区别
  Difference between Pulverized Coal Hot Stove and Gas Hot Stove
  [1]、炉膛受热面也很不一样,因为比较复杂,在这里就不详细说明了。
  [1], the furnace heating surface is also different, because it is more complex, not detailed here.
  燃油热风炉燃烧器必须有燃油物化装置,燃气热风炉燃烧器不需要物化装置。
  The burner of oil-fired hot blast stove must have a fuel physicochemical device, and the burner of gas-fired hot blast stove does not need a physicochemical device.
热风炉次使用要注意哪些问题
  [3]燃油热风炉采用燃烧器。在燃煤热风炉中,有固定炉篦、煤粉热风炉、起泡炉等燃烧方式。
  [3] Oil-fired hot blast stove uses burner. In the coal-fired hot blast stove, there are fixed grate, pulverized coal hot blast stove, foaming furnace and other combustion modes.
  燃油热风炉一般没有燃烧装置,燃烧的废气通过烟囱排出。而燃煤热风炉一般都有灰斗、渣机等除灰设施。
  Oil-fired hot stoves generally have no combustion device, and the exhaust gas from combustion is discharged through the chimney. The coal-fired hot blast stove generally has ash hopper, slag machine and other ash removal facilities.
  [5]燃油热风炉与燃气热风炉,就其主要结构而言,并没有很大的区别,只是由于燃油热值不同,受热面做出了相应的调整。即燃油热风炉辐射受热面较大,而煤粉热风炉是对流受热面设计的一些较大。
  [5] The main structure of oil-fired hot blast stove and gas-fired hot blast stove is not very different, but because of the different calorific value of fuel, the heating surface has been adjusted accordingly. That is to say, the radiation heating surface of oil-fired hot blast stove is larger than that of pulverized coal hot blast stove.
  [6]燃油热空气炉必须配备一个复杂的石油供应系统(特别是重油和渣油燃烧),如油箱、油泵、过滤器加热管道,等等,必须占据一定的空间,而燃气热空气炉不需要配备气体存储设备。只要把煤气管接到供气网络上就行了。当然,管道上应设置调压装置、电磁阀、缓冲阀等附件,以保证热风炉的安全运行。
  [6] Oil-fired hot air furnace must be equipped with a complex oil supply system (especially heavy oil and residue combustion), such as fuel tank, oil pump, filter heating pipeline, etc. It must occupy a certain space, while gas-fired hot air furnace does not need to be equipped with gas storage equipment. Just connect the gas pipe to the gas supply network. Of course, pressure regulating devices, solenoid valves, buffer valves and other accessories should be installed on the pipeline to ensure the safe operation of the hot blast stove.
