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.
Extensive Combustion Adaptability
The DHX steam boiler with CFB makes the newly developed coal particles fully mix with the developed coal particles, making the newly developed coal particles rapidly rise to the ignition temperature and burn.Therefore, all kinds of coal can be burned stably and efficiently. Almost all fuels, such as bituminous coal, lean coal, anthracite, petroleum coke, can be burned in CFB boilers, and can achieve stable combustion at 30% rated load.
High Efficiency
The fundamental difference between CFB boiler and other types of boiler lies in the combustion system, the thermal efficiency of CFB can reach more than 86%. Effectively reduce SOX and NOX emissions to meet environmental standards.
It is easy to realize the comprehensive utilization of ash and slag.
CFB technology allows coal to burn well enough to have a low carbon content in the ash. As a result, the ash is easy to reuse synthetically, such as for signs that can be used directly in cement and building materials.
