AFBC/FBC Boiler

AFBC Boilers are designed to handle a wide range of fuels while keeping emissions low and performance high. In these boilers fuel is burned by suspending fuel particles in a bed of heated bubbling bed and air. This allows better mixing of fuel and air, resulting in cleaner and efficient combustion — even with low-grade fuels like lignite, high-ash coal, petcoke, agro-waste and other biomass.
Fuel Options

Coal, Rice Husk, Biomass, Pet Coke, Dolochar Etc.

Capacity

02 TPH to 200 TPH

Working Pressure

Up to 110kg/cm²

Temperature

Up to 540°C (Superheated Steam)

Description

AFBC Boilers are designed to handle a wide range of fuels while keeping emissions low and performance high. In these boilers fuel is burned by suspending fuel particles in a bed of heated bubbling bed and air. This allows better mixing of fuel and air, resulting in cleaner and efficient combustion — even with low-grade fuels like lignite, high-ash coal, petcoke, agro-waste and other biomass.

AFBC Boiler can be distinguished by design & firing options:

  1. Overbed firing
  2. Under bed firing
  3. Overbed with bottom hopper
  4. Under bed with bottom hopper
  • 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:

  • Fuel Flexibility & Versatility: Capable of efficiently burning a wide range of fuels such as coal, lignite, rice husk, bagasse, petcoke, wood chips, and other biomass materials.
  • Eco-Friendly Low Emission Design: Ensures reduced emissions through controlled combustion, in-bed sulphur capture, and low NOx formation—supporting compliance with environmental regulations.
  • High Efficiency: Uniform and complete combustion results in improved heat transfer, higher thermal efficiency, and overall cost-effective operation.
  • Robust Construction: Manufactured using high-quality (grade) materials to ensure long service life, durability, and low maintenance needs.
  • Quick Start-Up & Load Response: Quickly reaches operating conditions and adapts well to varying industrial load demands.
  • User-Friendly Operation: Integrated with modern instrumentation and automation systems for easy control and simplified maintenance.
  • 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.

Salient 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.
  • Emission Control: Integrated with cyclones, ESPs, or scrubbers to minimize particulate matter and SOx/NOx emissions.
