Abstract
The temperature can nowadays be reduced by about 400° C. as a result of the cooling of the guide vane (,) of the first guide wheel. The many film bores leading outward from the guide vane (,) must therefore remain free of blockages or deposits caused by suspended matter in the cooling medium. Only pure gas must therefore be used as the cooling medium for the first guide wheel. This purpose is served by a dust separator which is designed advantageously as an axial cyclone (,′). The latter has no moving structural parts, has a simple design, is therefore insusceptible to faults and can be exposed to high temperatures. The axial cyclone is a centrifugal deduster without gas stream reversal.
