摘要

The prevention of corrosion on and in the area of a gas inlet connection by a nitric acid condensation, comprises forming a gas inlet opening (4) in the form of an annular gap by a sleeve, producing secondary air by providing an annular space (7) with a feed opening, so that it forms a peripheral flow (11) from secondary air around the entering nitric oxide gas and producing the secondary air curtain by injecting the secondary air over inlet holes at the connection. The connection has the sleeve in the transition area for the interior of the condenser (1) on the inner side of the connection. An independent claim is included for an arrangement for preventing corrosion on and in the area of a gas inlet connection by nitric acid condensation.
