Advantages and disadvantages of decomposing tube furnace
Ordinary Tubular Furnace
  Tube furnace is mainly used in metallurgy, glass, etc., decomposing tube furnace lithium battery positive and negative materials, new energy, abrasive tools and other industries to determine high-temperature professional equipment that must be under atmospheric conditions. He has the following advantages and disadvantages

    Advantages: mature skills; simple furnace structure; simple operation, easy to control, and continuous production; high yield of ethylene and propylene, high product concentration; low power consumption and high thermal efficiency; most of the cracked gas and flue gas can be managed Withdrawal; the scope of application of raw materials is gradually expanded with the advancement of cracking technology; it can be combined with multiple furnaces to produce large-scale production.

   Disadvantages: Because of the simple coking of heavy materials, the work cycle has to be shortened, the cracking depth is reduced, and the coking is often light, which shortens the useful production time throughout the year, and also affects the life of the cracking furnace and furnace tubes. When the result of lowering the cracking depth, the utilization rate of raw materials is not high, the quantity of low-value products such as heavy oil is large, and the cost of shared engineering also increases. According to the technical requirements of high temperature and short residence time and low hydrocarbon partial pressure, the external thermal strength of the furnace tube will inevitably increase, which requires the skills of oil-resistant alloy pipes and cast pipes.
