<p>The duct (40) has an end (40A) that is connected to a fluidizing feeder, and another end (40B) intended to be opened through machining shoulders (45) into a combustion chamber, where a separation zone (P1) is located proximate to the shoulders. An inner wall has two flats that are disposed proximate to the latter end, where the flats are arranged on upper and lower sides of the inner wall. The flats are opposite to each other such that the inner wall has a continuous and streamlined shape.</p> |
