PCT No. PCT/NL95/00319 Sec. 371 Date Mar. 4, 1997 Sec. 102(e) Date Mar. 4, 1997 PCT Filed Sep. 22, 1995 PCT Pub. No. WO96/10147 PCT Pub. Date Apr. 4, 1996Discharge pipe for discharging hot substances, which discharge pipe consists of an outer pipe, and an inner pipe placed coaxially inside the outer pipe, the inner pipe and the outer pipe enclosing a space, which is filled up with insulating means. The insulating means consist of a first layer (7) of compressible material surrounding the outside of the inner pipe (3), and a second layer (6) of concrete with very good thermal insulating properties which surrounds the first layer (7) and is surrounded by the outer pipe (2). The inner layer (7) consists of compressible material with high thermal insulation properties, such as ceramic wool. The discharge pipe is made up of several lengths of pipe (1), the successive lengths of pipe being fixed to each other by means of fixing means (13), and a compressible layer (12) of material with good thermal insulating properties, being placed between the contact faces of two successive lengths of pipe. |
