Introduction
CFBC technology is a new, efficient, and low-pollution clean coal method. This low-temperature combustion significantly reduces Nitrogen Oxide emissions and enables direct, high-efficiency desulfurization. Economically straightforward, CFBC lowers costs compared to other methods and accommodates various fuels, including low-calorific, low-quality coal. The resulting ash is reusable, eliminating secondary pollution. Moreover, CFBC supports wide load adjustments, operating down to about 30% of full load.
