Abstract
By a method and a device for preventing corrosion on and in the region of a gas inlet nozzle during nitric acid condensation, contact of the condensing gas with the nozzle and with the surroundings of the nozzle are supposed to be minimized. This is achieved in that the gas inlet nozzle has a sleeve on the inside in the transition region to the interior of the condenser, by which sleeve a gas inlet orifice in the form of an annular gap is formed, whereby the annular space is provided with at least one feed opening for secondary air, so that an enveloping flow of secondary air is produced around the entering NO gas.
