Dual Circulation CFB process, abbreviated as DC-CFB, uses CaO or Ca(OH)2 as desulfurization agent, utilizing high-efficiency fluidized bed reaction tower and matching low-pressure pulse reverse blowing bag filter for high-efficiency desulfurization and dust removal, while removing other acidic pollutants such as HCl and SO3 from flue gas. The fluidized bed reaction tower can adsorb and solidify trace heavy metals such as lead, cadmium, mercury, and pollutants like dioxins.
Double-curved Venturi: Uniform flow field, low resistance
Dual circulation desulfurization system: Combination of large and small cycles, self-regulating control, load self-adaptive, low-consumption operation
Double-layer multi-nozzle dual-fluid spray gun atomization: Fine mist uniform distribution, enhanced reaction, saving desulfurization agent and reducing calcium-to-sulfur ratio
Venturi upper return material: Drag reduction and energy saving, protects tower body, ash hopper requires no material seal, completely solves ash hopper hardening problem during ash discharge operation
Weighing ash hopper: Individually supported + weighing level gauge, visualized precise level control, safe, low-consumption, easy maintenance
Low cost: 6-10% power saving, 10-15% agent saving, less slag that can be resourced, low treatment cost
High reliability: Precise material control without hardening, multiple interlocks for stable operation
Strong adaptability: 0~110% wide load range, full-process automatic regulation
