...Fireside corrosion of superheater tubes in waste incinerators has been a long-term issue for boiler fabricators and tube manufacturers considering high-efficiency waste-to-energy (WTE) plants. Ambitious performance goals have been set in various countries ^{1 , 2} , but the selection...

... plants require new corrosion-resistant materials for superheater applications and many efforts have been carried out to investigate the corrosion behavior of desirable new materials in waste incinerators( 1 )( 2 )( 3 ). Y. Kawahara et al. revealed the relationship between the corrosion...

... corrosion resistant superheater tubes are a critical component for the success of future municipal waste incinerators designed to operate with a steam temperature of 500°C and 100 ata pressure. In an effort to meet the challenge of producing such a component, 347SS tubes were overlaid with alloy 6M (Ni-20wt...

... such as lead and zinc in waste are the principal factors in the fuel chemistry which cause severe corrosion attack of superheater tubes in waste incinerators. high temperature corrosion waste incinerator fused salt hot corrosion fireside corrosion superheater tube INTRODUCTION Studies showed...

...Abstract Protective coatings produced by high velocity flame sprayings can be useful in combating the hot corrosion experienced in waste incinerators. The D-GUN and HVOF coating processes produce poreless high quality coating layers with strong adherence to substrate materials. Laboratory tests...

... from corrosion test probes in existing waste incinerators exposed at 550°C for 700 h and 3000 h was measured by DSC in a simulated flue gas atmosphere. Heat of fusion was summationed for up to 550°C, and the sum was considered to represent the relative amount of fused salts in the deposits at 550°C...

...Abstract Recently, a new corrosion resistant Ni-Cr-Mo-Ta alloy, MAT-21, alloy T, was developed with improved corrosion resistance to sulfuric acid dewpoint corrosion which occurs in fossil fuel-fired power plants. Under conditions simulating acid dewpoint corrosion in waste incinerator flue gases...

...Abstract Laboratory corrosion tests simulating environments of superheater tubes in waste incinerators were conducted to obtain information on the performance of 17 commercial "corrosion resistant" steels and alloys. The steels and alloys were corroded in a simulated flue gas atmosphere containing...
