Intec Fluidised Bed Firing

The fluidised bed firing promises efficient combustion of low-quality fuels. A wide range of fuels can be used for firing, with high efficiency.

Instead of a grate, the combustion chamber is filled with a bed of inert material (e.g. sand). Air is blown into the bed from underneath through nozzles in order to fluidise the bed.

The fluidised bed and the combustion chamber are heated to the fuel ignition temperature and then fuel and distributed in the bed. The fuel catches fire and burns.

Complete burnout takes place in the combustion chamber above the bed. Heating surfaces immersed in an adjacent fluidised bed conduct usable heat out of the bed material.
