Final answer:
The working principle of FBC involves suspending solid particles in a bed of inert material that is fluidized by a flow of air or gas, creating a turbulent mixing and heating environment. A diagram of FBC typically shows a bed of solid particles, an inlet for fuel and air, a combustion chamber, and an outlet for combustion gases. Bubbling fluidized bed (BFB) is one example of FBC, where the bed material exhibits both fluid-like and solid-like behavior, enhancing combustion efficiency.
Step-by-step explanation:
The working principle of FBC (Fluidized Bed Combustion) involves suspending solid particles in a bed of inert material that is fluidized by a flow of air or gas. This creates a turbulent mixing and heating environment that enhances combustion efficiency. A diagram of FBC typically shows a bed of solid particles, an inlet for fuel and air, a combustion chamber, and an outlet for combustion gases. One example of FBC is the bubbling fluidized bed (BFB), where the bed material has a particle size distribution that allows it to exhibit both fluid-like and solid-like behavior. In BFB, the solid particles are fluidized and bubbles are formed, providing a large contact area for fuel and air, resulting in efficient combustion.
