AFBC/FBC Boiler
AFBC (Atmospheric Fluidized Bed Combustion) and FBC (Fluidized Bed Combustion) boilers are advanced combustion systems designed to burn a wide range of low-grade fuels efficiently. By suspending fuel particles in a bed of heated air, these boilers ensure uniform combustion, reduced emissions, and high thermal efficiency. Ideal for industries seeking cost-effective and eco-friendly steam generation.
Fuel Options
Coal, rice husk, biomass, petcoke, sludges
Capacity
10 TPH to 200 TPH
Working Pressure
Up to 120 kg/cm² (IBR-certified)
Temperature
Up to 540°C (superheated steam)
Advantages
- Low-Cost Fuel Utilization: Optimizes low-grade or waste fuels.
- Uniform Combustion: Fluidized bed ensures complete fuel burnout.
- Adaptability: Suitable for fuels with high moisture or ash content.
- Cogeneration Ready: Integrates with power turbines for combined heat and power (CHP).
- Fuel Efficiency: Reduces operating costs with high combustion efficiency.
- Eco-Friendly: Lowers emissions through controlled combustion and pollution control systems.
- Versatility: Handles multiple fuel types in a single system.
- Compact Design: Requires less space compared to conventional boilers.
- Low Maintenance: Robust construction minimizes downtime.
Key Points
PP Boilers’ AFBC/FBC boilers are engineered to handle diverse fuels, including coal, biomass, agro-waste, and industrial sludges. Key design elements include:
- Fluidized Bed Technology: Enhances combustion efficiency by suspending fuel in a turbulent air stream.
- Fuel Flexibility: Burns low-calorific fuels like rice husk, coal rejects, and petcoke.
- Emission Control: Integrated with cyclones, ESPs, or scrubbers to minimize particulate matter and SOx/NOx emissions.
- Modular Construction: Simplifies installation and maintenance.
Features
- In-Bed Coils: Studded coils for enhanced heat transfer in the fluidized bed.
- Advanced Air Distribution: Nozzles ensure uniform air-fuel mixing.
- Ash Recycling: Re-injects unburned particles for improved efficiency.
- Automated Controls: PLC-based systems for real-time monitoring and adjustments.
- Durable Refractory Lining: Withstands high-temperature combustion environments.
Applications
- Power Plants: Captive and co-generation power units.
- Textiles: Steam for dyeing and drying processes.
- Chemicals: Process heating and reactor systems.
- Paper Mills: Steam generation for pulp drying.
- Distilleries: Combustion of spent wash and biomass blends.
