Abstract (en)

[origin: US4444154A] The fluidized bed is situated in a combustion chamber formed from evaporator tubes welded in seal-tight relationship and leading into a gas flue. The combustion chamber is connected to the gas flue via two inclined connecting wall surfaces. Heater tubes bent into an L-shape extend through the fluidized bed. Each shorter limb of the heater tubes extends substantially vertically while the other longer limb extends substantially horizontally. The horizontal limbs pass through a substantially vertical combustion chamber wall at the level of the fluidized bed and the vertical limbs pass through the free surface of the fluidized bed beneath the connecting wall surface. As a result of this arrangement of the heater tubes, the stresses therein due to uneven thermal expansion of the heater tubes remain within permissible limits.
