Morphology
The phrase is compositionally built: it denotes a boiler that uses a 'fluidized bed' — if a learner knows 'fluidize' (make particles behave like a fluid), 'bed', and 'boiler' they can infer it is a boiler in which a layer/bed is fluidized. However, the exact technical process and implications (suspended particles, combustion efficiency, reduced emissions) are domain-specific, so full understanding goes beyond everyday vocabulary.
Etymology
Fluidized bed boiler gets its name from the image of a bed of small hot particles that is made fluidized, so it moves and bubbles and the fuel is 'burned while floating' among the grains. That bubbling, floating mix helps the fuel burn more fully, so the boiler is more efficient and makes fewer harmful gases.
