E101 LOW NOx COMBUSTION SYSTEM FOR HEAVY OIL : 2^<nd> REPORT

概要

論文の詳細を見る
This paper shows a new combustion system called KACC (Kawasaki Advanced Clean Combustion) on utilize heavy oils such as asphalt or Orimulsion directly for boiler fuel suppressing the Nox emission. The concept of this system is to realize the furnace of high temperature and strong reduction condition. Through the test carried out using 18MWth test rig, it was proved that this technology is available to keep NOx emission below 100ppm. Further more the urea solution injection method was tried for Orimulsion firing, and NOx emission was reduced by 20-30%. Three industrial boilers were constructed based on this concept. The have been operating successfully, and each NOx emission was lower than expected.
