PCI tube manufacturing process in the country this is a difficult topic. The main questions focused on two points: First, the inner and outer wall of coal injection pipe into place easily worn pink; the second is heat-resistant steel head was oxidized surface temperature kiln flame. European ceramics with high temperature glue and heat resistant steel head Boriding technology adoption. Domestic high temperature plastic hard to find, no Boronizing process developed. Imported coal injection pipe is generally a price of $ 10 to 15 million. Domestic manufacturers are imported from Germany, a one (2) into the pulverized coal injection pipe at guard (Φ245 × 6 × 1220), spent 60,000 yuan entire burner boiler is actually processed by Boronizing seamless Q235A pipe. Currently gas burner bright spot is that energy, security and technological innovation, this sun Shanxi Environmental Protection Equipment Co., Ltd. will own unique burner presented to the user. 1 in terms of the heat transfer coefficient kcal / m 2.
