What are the characteristics and working principle of circulating fluidized bed boiler?

30 Jun 2023

Circulating fluidized bed (CFB) boilers are a type of combustion technology that is commonly used for power generation and industrial applications. The following are the characteristics and working principle of circulating fluidized bed boilers:

 

Characteristics:

 

High combustion efficiency: CFB boilers have high combustion efficiency due to the large surface area of the bed particles and the high turbulence created by the fluidizing air.

 

Fuel flexibility: CFB boilers can burn a wide range of fuels, including coal, biomass, and waste materials. This makes them a versatile choice for power generation and industrial applications.

 

Low emissions: CFB boilers can operate with low emissions of nitrogen oxides (NOx) and sulfur dioxide (SO2) due to the use of limestone or other sorbents to capture these pollutants.

 

Low maintenance: CFB boilers have simple and robust construction, which reduces the need for maintenance.

 

Working principle:

 

The working principle of a CFB boiler involves the combustion of fuel in a bed of particles, which are suspended in a high-velocity stream of air. The bed of particles is fluidized by the air, which causes the particles to behave like a liquid and circulate through the combustion chamber. The bed acts as a heat sink, absorbing heat from the combustion process, and transferring it to the circulating particles, which in turn transfer the heat to the water in the boiler's tubes.

 

The combustion process in CFB boilers is controlled by adjusting the flow of air and fuel into the combustion chamber, as well as the addition of sorbents or other additives to control emissions. The combustion temperature is typically lower than that of conventional boilers, which helps to reduce the production of nitrogen oxides.

 

Overall, CFB boilers offer a number of advantages over other types of boilers, including high efficiency, fuel flexibility, low emissions, and low maintenance requirements.
