摘要 |
The present invention provides a heat exchanger (32) for heating a fluid (26) in an incineration plant (2), the incineration plant (2) in operation producing a flue gas (34), the heat exchanger comprising at least one heat exchanger component (40) comprising a wall having a first side (46) in contact with the fluid (26), and a second side (48) in contact with the flue gas (34), the second side (48) being provided with a protective oxide (50) for protecting the heat exchanger component (40) against corrosion caused by corrosive compounds entrained or comprised by the flue gas (34), wherein the protective oxide (50) comprises α-Al2O3. A method of forming a scale (50) for protecting a heat exchanger component (40) against corrosion caused by corrosive compounds entrained or comprised by a flue gas (34) is also provided. |
