Abstract: High temperature corrosion is one of the key factors restricting the long-term stable operation of waste incineration power plants. A waste heat boiler of a waste incineration power plant was taken as the research object， the gas temperature， steam temperature， tube wall temperature of superheater and the distribution of velocity filed in furnace before and after modification were analyzed. The results showed that the high temperature corrosion risk of the superheater could be reduced by strictly controlling the tube wall temperature of superheater through optimizing the layout of heating surface and designing the furnace arch， and improving the non-uniformity of flow field scouring in the horizontal gas pass. At the same time， the corrosion resistance of 12Cr1MoVG material was decreased evidently when the wall temperature was higher than 472 ℃， while TP347H material still had good corrosion resistance when the wall temperature was about 493 ℃ and below. It was recommended that when the wall temperature was higher than 465 ℃， stainless steel with corrosion resistance no less than TP347H or other anti-corrosive processes could be used for tube wall.

Key words: waste incineration, waste heat boiler, high temperature corrosion, design optimization
