List of basic data required for the design of flue gas desulfurization projects (CFB-FGD flue gas desulfurization process): Basic parameters of sintering equipment. Equipment model: Burning method: Exhaust gas temperature in °C. Flue gas volume in Nm3/h. Initial dust content in the flue gas in g/Nm3. SO2 concentration in the flue gas in mg/Nm3. Other components in the flue gas: HCl, HF, NOx, O2. Existing flue gas purification system. Dust collector model: Dust removal efficiency under current operating conditions: Capacity of the existing dust collector’s ash removal system. Parameters of the exhaust fan: Number: Flow rate: Total pressure: Motor power. Site conditions: Floor plan of the site where the flue gas treatment system will be installed for desulfurization purposes. Modify the geological data of the site. Treatment of fly ash and desulfurization slag; Dust particle size distribution data; Dust composition analysis; Storage requirements and duration for storage sites; Transportation methods and distance requirements; Desulfurizing agents; Sources of raw materials for desulfurization processes – quicklime or slaked lime (calcium carbide slag) ； Is a desulfurizer preparation system required? Desulfurizer quality ； On-site cost ； Water: Wastewater can be utilized comprehensively; the water quality is preferred to be alkaline. Water quality report: Chloride content should be less than 100 mg/l. Compressed air: Quality of the compressed air source – oil-free/oil-containing. Supply pressure in MPa; available supply volume in m3/min. Reserve capacity of power supply facilities – sufficient to meet additional electrical demands. Voltage output of the power source; wiring method. Environmental standards: Standards applied for environmental protection in the user’s location. Dust emission concentration; sulfur dioxide emission concentration. User’s views on the comprehensive utilization of fly ash. Required control levels; requirements regarding the automation level of the desulfurization system, which should be consistent with or matching the control level of the generator set. The communication signals between the (PLC/DCS) control system and the host require signals provided by the desulfurization system. Funding situation: Funding source – self-financing/bank loan. Economic evaluation: The basic data for calculating desulfurization costs are listed in the “Basic Data Table for Economic Evaluation”
