Description

Atmospheric fluidized bed combustion (AFBC) boilers (Hybrid Shell-cum-Watertube Membrane wall panel) advanced combustion systems designed to burn solid fuels, such as coal or biomass, efficiently and with reduced emissions. Here's a brief overview of their key features and advantages:

 

Key Features

  • Fluidized Bed: In AFBC, fuel is suspended in a stream of air, creating a "fluidized" state. This enhances mixing and heat transfer, leading to more uniform combustion.
  • Lower Temperature: AFBC operates at lower temperatures (typically around 850-900°C) compared to conventional combustion methods. This helps reduce the formation of nitrogen oxides (NOx).
  • Flexibility: AFBC can burn a wide range of fuels, including low-quality or waste fuels, making it versatile for different applications.
  • Ash Handling: The fluidized bed can help manage ash production effectively. Ash can be removed continuously, minimizing operational interruptions.
  • Environmental Benefits: AFBC systems generally produce lower emissions of SO2 and NOx compared to traditional combustion methods, making them more environmentally friendly.

Specifications

Advantages

  • Efficiency: The fluidization process improves combustion efficiency, often resulting in better fuel utilization.
  • Reduced Emissions: Lower combustion temperatures and better fuel mixing contribute to reduced harmful emissions.
  • Wide Fuel Range: The ability to utilize various fuels makes AFBC suitable for diverse energy needs.
  • Operational Stability: The system is more stable under varying loads, allowing for flexible operation.

Applications

 

AFBC boilers are commonly used in power generation, industrial heating, and waste-to-energy plants, where their efficiency and environmental benefits can be maximized.
