What you should know about waste-to-energy incineration

Blog |

What is waste-to-energy? Currently, there are three primary methods for disposing of household waste: sanitary landfilling, composting, and incineration for power generation. However, landfilling requires a significant amount of land and can easily lead to secondary pollution. Composting is slow and only suitable for small-scale applications. As a result, incineration for power generation has become

What’s the difference between elliptical and circular tube in air preheaters

Blog |

Elliptical tube air preheater has a significant improvement in efficiency compared to traditional circular tube. The original circular tube air preheater suffers from high wind resistance and low efficiency. In comparison, elliptical tubes offer better aerodynamic properties, lower flow resistance, and longer time for dust to accumulate between them. With equal cross-sectional areas, elliptical tubes
