Summary

Different types of swirl coal burners are presented, along with developments in radial-biased combustion and centrally-fuel-rich swirl coal combustion technology. In air and in air/particle test facilities, a single-sensor hot-film and anemometers have been used to measure air and air/particle flows in the near-burner region of different swirl burners. This book shows the experimental results and how the two new burners simultaneously have the advantages of high combustion efficiency, flame stability, low NOx emission, and resistance to slagging and high-temperature corrosion. The air-surrounding-fuel combustion theory was put forward.
