Description

Verfahren zur Reinigung verkrusteter 1Vletallflächen Nach dem durch das Patent 473 320 geschützten Verfahren werden Metallflächen, insbesondere die feuergasberührten Wandungen von Kesseln, mittels eines Gebläsebrenners gereinigt, der mit einem unter niedrigem Druck zugeführten ölsauerstoffgemisch und mit unter höherem Druck der Flamme gesondert zugeführtem Sauerstoff betrieben wird. Es wird auf diese Weise an der Brennermündung eine büschel- oder strahlenförmig ausgebreitete Flamme erzeugt, die einen verhältnismäßig großen Teil der zu reinigenden Fläche bestreicht und von so niedriger Temperatur ist, daß sie zwar die Verunreinigungen lockern, zermürben und absprengen, aber das zu reinigende Metall nicht beschädigen kann, und die endlich auch die abgesprengten Teile fortbläst.Process for cleaning encrusted metal surfaces According to the process protected by patent 473 320 , metal surfaces, in particular the boiler walls that come into contact with the flue gas, are cleaned by means of a forced draft burner which is operated with an oil-oxygen mixture supplied at low pressure and with oxygen supplied separately to the flame at higher pressure. In this way, a tufted or radiant flame is generated at the burner mouth, which spreads over a relatively large part of the surface to be cleaned and is of such a low temperature that it loosens, wears down and blasts off the impurities, but the metal to be cleaned cannot damage it, and which finally blows away the parts that have been blown off.

Es hat sich nun beim Gebrauch dieses Verfahrens ergeben, daß man statt reinen Sauerstoffs auch atmosphärische Luft, die unter einem entsprechend hohen Druck steht und an Stelle von Öl auch.andere geeignete Brennstoffe verwenden kann. Durch die Verwendung von anderen Brennstoffen wird neben der Verbilligung des Betriebes noch der Vorteil erreicht, daß man an bestimmte Formen des( Brennstoffes nicht gebunden ist und durch entsprechende Auswahl des letzteren die Temperatur der Flammen regeln kann. Durch die Verwendung von Druckluft ist ferner die Möglichkeit gegeben, die Temperatur der erzeugten Flamme besonders niedrig zu halten.It has now been found when using this method that instead of pure oxygen also atmospheric air, which is below a correspondingly high level Pressure is available and can use other suitable fuels instead of oil. The use of other fuels also makes the operation cheaper nor achieved the advantage that one is not bound to certain forms of (fuel and regulate the temperature of the flames by selecting the latter accordingly can. The use of compressed air also gives the possibility that To keep the temperature of the flame generated particularly low.
