AI Technical Summary

Technical Problem

The existing primary air distribution structure of incinerators results in insufficient filling of the air chamber, uneven air distribution, unstable combustion, low combustion efficiency in oxygen-deficient areas, and easy generation of harmful gases such as carbon monoxide.

Method used

The gas flow is preheated by heating components and distributed into the incinerator through multiple pipes, including the main air duct, the annular air duct and the telescopic branch pipe, forming an annular air curtain to uniformly replenish oxygen and heat. The gas temperature control is improved by using arrayed and staggered heating tube groups.

Benefits of technology

It improves the combustion efficiency and stability of the incinerator, reduces the generation of harmful gases, and extends the combustion time.
