搪瓷管预热器的用处又表现在哪里呢?
What is the use of enamel tube preheater?
咱们先来看一组数据，在现代的工业锅炉和电站锅炉中，空气预热器低温腐蚀和堵灰表象时有发生，这关于锅炉和机组的安全、经济运转构成了难题，尤其在燃用高硫分煤种时，疑问愈加杰出。而我国热电厂中的空预器占锅炉全体出资的6%-8%，每年由于以上疑问形成的设备替换与停产清灰费用约占运转本钱的4 %-5%，丢失非常大。
Lets first look at a set of data, in the modern industrial boiler and power plant boiler, low temperature air preheater corrosion and ash clogging representation have occurred, this a unit boiler and the safety, economic operation constitute a problem, especially in the burning high sulfur coal, doubt is more and more outstanding. And the air preheater in the thermal power plant of China accounts for the boiler 6%-8%, due to the above questions every year the formation of equipment replacement and production clearance costs about 4%-5% running costs, lost very large.
而搪瓷管预热器则改变了这一局面，研发人员在预热器的烟气进口烧制了一种高温的珐琅涂层，取消了传统的金属套管的运用，然后加大了空气的流转面积，并降低了烟气的流转速度，使磨损明显减。除此之外，珐琅涂层的运用还解决了低温腐蚀状况，再加上珐琅的外表非常润滑，故不容易发生积灰，有用减少了预热器的积灰阻塞疑问。这些都是空预器的价值表现。
And enamel tube preheater has changed this situation, R & D personnel in the flue gas inlet of the preheater fired a high-temperature resistant enamel special coating, the abolition of the use of traditional metal casing, then increase the air circulation area, and reduces the flow speed of the flue gas and the wear significantly reduced. In addition, the use of enamel coating is completely solved conditions of low temperature and corrosion, and the appearance of the enamel is very slippery, so it is not easy to produce dust deposit, effectively reduce the accumulation of ash blocking doubt preheater. These are the value of air preheater performance.
