Recently, we have constructed a new heavy oil boiler (N 1 boiler) and steam turbine (N 1 turbine) to reduce energy cost in our Kishu Mill.
This new system replaced the less efficient old boiler and turbine. This N 1 boiler is equipped with a newly developed unique low-NOx combustion system. This paper introduces the data of the NOx emission obtained during the short period from the trial to the normal operation.
