ABSTRACT:
A process for manufacturing a flue made of fiber-reinforced plastic (FRP), particularly of a stack for discharging chemically aggressive fumes, consists of manufacturing the FRP flue directly inside the stack. The apparatus for performing this process includes a rotating carousel which supports a first work station, a second work station and at least a third work station to progressively and constantly deposit on a stationary mold at least one first layer of chemically-resistant material and at least one layer of mechanically-resistant material in order to form, without discontinuities, a central portion of the flue of the stack.
