We need the low-NOx coal combustion system for small boilers. However, conventional methods of low-NOx coal combustion are not effective in small boilers because of the very high combustion rate.
We therfore developed new-low-NOx and low-carbon in flyash coal combustion system for small compact boilers using the Coal Partial Combustor technologies.
This technologies are based on NOx-decomposition with high temperature atmospheres under fuel-rich conditions.
In this paper, the new-low-NOx coal combustion technology for compact coal combustion boilers and the results of combustion tests are reported.
