使用工业锅炉生产时需要注意什么

  工业锅炉产品重要分为两种,一种是蒸汽,主要是用于发电的,一种是供电的,以煤为原料,这就是比较常见的工业锅炉类型。具体使用工业锅炉生产时需要注意什么呢?下面就为大家做详细的介绍。

  锅炉生产时需要降低锅炉排烟温度,因为锅炉排烟是热损失最大的一项,排烟量的大小主要取决于排烟温度的高低,所以降低排烟温度是提高锅炉热效率的重要一项措施。在使用过程中要避免热面上有结渣或者积灰的情况,

  如果遇到灰尘比较多,需要定期吹灰,对于松散的积灰可定期用吹灰的方法清除,如果附着在管子上的时间比较长,就会变得越来越厚。因为积灰会生产粘结性的硫酸盐和亚硫酸盐等,时间长了不容易清洗,吹灰的介质可以选择过热蒸汽、压缩空气和惰性气体等。

  另外还要投入一定量的锅炉清灰剂,锅炉在燃烧运行时需要投入一定量的清灰剂,进入炉膛之后会生化分解,炉受热面的结焦、结渣接触并渗透到受热面,发生微爆反应分解高温结渣,使其分解、脱落,可减少和防止烟垢的生成。

  工业锅炉生产中要增加或者改进尾面受热面,因此要增加锅炉的金属耗量和烟气的流动阻力,遇到含硫高的燃料时,排烟的温度要保持高一些。合理的排烟温度必须从金属与燃料的比价,运行维修费用的增加等方面进行技术经济比较来确定。

  Industrial boiler products are mainly divided into two types, one is steam, which is mainly used for power generation, the other is power supply, using coal as raw material, which is a relatively common industrial boiler type. What should I pay attention to when using the industrial boiler? Here's a detailed introduction for everyone.

  Boiler production needs to reduce the boiler exhaust temperature, because the boiler exhaust heat is the largest one, the amount of exhaust depends mainly on the level of exhaust gas temperature, so reducing the exhaust gas temperature is to improve the thermal efficiency of the boiler an important measure . In the use of the process to avoid slag or dust on the hot surface,

  If you encounter more dust, the need for regular soot, for loose dust can be regularly used soot removal method, if attached to the pipe for a long time, it will become thicker and thicker. Since dust deposits produce cohesive sulphates and sulfites, it is not easy to clean for a long time, and soot blowing media can be selected from superheated steam, compressed air and inert gas.

  In addition, a certain amount of boiler cleaning agent needs to be put into operation. When the boiler is operating in combustion mode, a certain amount of cleaning agent needs to be put into the furnace. After entering the furnace, it will be biochemically decomposed, and the coking and slagging of the heating surface of the furnace come into contact with and infiltrate the heated surface. The explosive reaction decomposes the high-temperature slag to make it decompose and fall off, which can reduce and prevent the formation of soot.

  Industrial boiler production to increase or improve the heating surface at the end, so to increase the boiler metal consumption and flue gas flow resistance, met the high sulfur fuel, the exhaust gas temperature to be kept higher. Reasonable exhaust gas temperature must be determined from the technical and economic comparison between the ratio of metal to fuel and the increase of operating and maintenance costs.
