Abstract
To improve the performance of "JFE Hyper 21 Stoker System", an advanced stoker-type incinerator, we have modified High-temperature Air Combustion Technology (HiCOT). In this paper, the effect and characteristics of modified HiCOT are examined. In verification tests, stable combustion with lower NOx emission is demonstrated at air excess rate 1.3. In a numerical simulation, calculated internal temperature distribution of the incinerator is agreed with measured that in verification tests qualitatively. In case of applying modified HiCOT to actual waste incinerator, increase of power generation is expected by increase of steam flow for turbine which is due to eliminating a catalytic denitrification equipment.
