How does the INTEC fuidised bed combustion work?
A material bed is filled with inert material.
Air is introduced from the bottom, air bubbles are forming
The material starts to move, it gets whirled around and fluidised.
The sand/air mixture behaves like a fluid.
The fluidised bed is heated by the start-up burner to ignition temperature, then the fuel is introduced onto the fluidised bed.
Immersed heat transfer tubes absorb the heat from the overflowing bed.
