  Atmospheric Fluidized Bed Combustion (AFBC) Boilers are an efficient and cost-effective solution for process heating and power generation. Known for their high combustion efficiency (over 85%), they can burn a wide range of fuels including Indian/imported coal, lignite, rice husk, petcoke, and washery rejects.

  These boilers offer multiple advantages such as quick start-up, simple operation, fast response to load changes, and low operating costs. Their design ensures high reliability and flexibility in fuel usage. Features like a water wall membrane, four-stage steam separation, and studded in-bed evaporator tubes enhance performance and durability.

  AFBC boilers are also designed with environmental and maintenance benefits in mind. The hopper bottom furnace reduces wear since there are no moving parts, and the fluidized bed ensures uniform combustion with low NOx, SOx, and CO emissions. The system also supports limestone addition for sulfur control and has built-in mechanisms to avoid ash agglomeration.

  Additionally, the boiler allows for under-bed or over-bed fuel feeding and is available in bi-drum or single-drum designs—suitable for both saturated and superheated systems. With a secondary firing system and energy-efficient fans, AFBC boilers deliver reliable, clean, and cost-effective energy solutions.
