Frequently Asked Questions
CFB Boiler Technical FAQ
Common questions from EPC contractors, power plant operators, and industrial end users considering CFB boiler technology for their projects.
What is the typical efficiency of CFB boilers compared to pulverized coal boilers?
Modern CFB boilers can achieve net efficiency up to 90% (LHV basis) when properly designed and operated. Compared to pulverized coal (PC) boilers, CFB technology offers:
- • Similar or higher efficiency: Especially with lower-grade fuels where PC boilers struggle
- • Better part-load efficiency: CFB maintains high efficiency at 50-70% load
- • Lower auxiliary power: No need for coal pulverizers and associated equipment
- • Fuel flexibility advantage: Can burn waste fuels that PC boilers cannot handle economically
Final efficiency depends on fuel properties, steam parameters, and auxiliary equipment selection. We provide detailed efficiency calculations during the proposal stage.
How do CFB boilers handle fuel variations and what is the minimum/maximum fuel quality?
CFB boilers are exceptionally tolerant to fuel quality variations. Typical fuel ranges we can accommodate:
Coal & Solid Fuels:
- • Calorific value: 8-30 MJ/kg
- • Ash content: 5-60%
- • Moisture: up to 45%
- • Sulfur: up to 4%
Biomass & Waste:
- • Bagasse, wood chips, rice husk
- • Municipal solid waste (MSW)
- • Industrial waste and sludge
- • Co-firing ratios up to 100%
The fluidized bed naturally accommodates fuel variations through automatic mixing and temperature control. We design each system based on your specific fuel analysis and expected variations.
What are the maintenance requirements and typical maintenance costs for CFB boilers?
CFB boilers generally have lower maintenance costs than PC boilers due to simpler fuel handling and no pulverizers. Typical maintenance schedule:
Planned Maintenance:
- • Annual shutdown: 2-3 weeks for inspection, refractory repair, tube cleaning
- • Major overhaul: Every 3-4 years (4-6 weeks) for cyclone refractory, water-wall inspection
- • Daily maintenance: Routine inspection, ash removal, water treatment
Key Wear Items:
- • Cyclone separator refractory lining (3-5 year life)
- • Lower furnace refractory and cladding (2-4 year life)
- • Distributor plates and nozzles (5-8 year life)
- • Bed material replenishment (continuous, low cost)
Maintenance costs are typically 15-25% lower than PC boilers. We provide detailed maintenance manuals, spare parts recommendations, and training for your maintenance team.
How do you achieve SO₂ and NOₓ emission control in CFB boilers?
CFB technology inherently produces lower emissions than conventional combustion systems. Our emission control approach:
SO₂ Control:
- • In-furnace desulfurization: Limestone injection directly into the bed
- • Capture efficiency: 85-95% SO₂ removal achievable
- • Ca/S ratio: Typically 2.0-3.0 for high sulfur coals
- • No wet FGD required: Reduces capital and operating costs
NOₓ Control:
- • Low combustion temperature: 850-900°C reduces thermal NOₓ
- • Staged combustion: Primary/secondary air distribution optimization
- • SNCR option: Urea/ammonia injection for ultra-low NOₓ
- • Typical emissions: <200 mg/Nm³ without SNCR, <100 mg/Nm³ with SNCR
Emission guarantees are provided based on fuel analysis and local regulatory requirements. We can meet EU, US EPA, and other international emission standards.
What is the typical delivery time and project timeline for CFB boiler supply?
Project timeline depends on boiler size, scope of supply, and technical complexity. Typical schedules:
Engineering & Manufacturing:
- • Small CFB (6-35 t/h): 8-12 months from contract
- • Medium CFB (35-130 t/h): 12-16 months from contract
- • Large CFB (130+ t/h): 16-24 months from contract
- • Detailed engineering: 2-3 months for drawings and calculations
Project Milestones:
- • Contract signature to detailed drawings: 8-12 weeks
- • Manufacturing start to first shipment: 6-8 months
- • Site erection and commissioning: 3-6 months
- • Performance testing and acceptance: 1-2 months
We work closely with EPC contractors to optimize delivery schedules and coordinate with civil works. Expedited delivery options available for urgent projects with premium pricing.
What technical support and services do you provide during commissioning and operation?
