Abstract

Fireside corrosion of boiler tubes in bio medical waste incinerator plants has been of great concern for plant operators, boiler designers, and boiler tube manufacturers since quite a few number of boiler tubes in these plants suffered from wall thinning due to hot corrosion. The corrosion problem at high temperature is more serious due to the highly aggressive environment in bio medical waste incinerator plants such as Cl , HCl, alkali metals and heavy metals. 2 Corrosion resistant coatings are the key technologies to reduce the maintenance in bio medical incinerator plants by reducing the hot corrosion problem. Different corrosion resistant coatings processes have been developed such as thermal spray, HVOF, HVSFS, PVD and cold spray. Employing the corrosion resistant coatings ensure the high corrosion and wear resistant of the boiler tubes. This paper highlights the hot corrosion in bio medical incinerator plants, its effects and its protection with corrosion resistant coatings. Cold spray coatings have been reviewed with the aim of summarizing their high temperature corrosion resistance properties.
