Hot corrosivity of coal conversion product on high temperature alloys. Final report

Description: This report describes research begun under Contract AS01-76-ET-10577, most of which was continued when the same project was continued under a new number, Contract AC01-79-ET-13547. The areas studied are thermochemistry of high temperature corrosion, hot corrosion of turbine alloys and coatings, and electrochemistry of sulfate melts. A background to the problem of hot corrosion is presented first followed by a description of results obtained in the three areas of this project.

Hot corrosivity of coal gasification products on gas turbine alloys. Summary report, 15 April 1978-15 November 1979

Description: The results of this investigation have produced mechanisms for the hot corrosion of a number of pure metals and alloys in the types of atmospheres likely to be obtained in turbines using coal conversion products as fuel. The results of these mechanistic studies suggest the following conclusions regarding application of alloys in these situations: (1) Simple Cr/sub 2/O/sub 3/-forming alloys of both Co and Ni have good hot corrosion resistance to most of the deposits likely to form in turbines bu… more

Report covering examination of parts from downhole steam generators. [Combustor head and sleeve parts]

Description: Combustor head and sleeve parts were examined by using optical and scanning electron metallography after use in oxygen/diesel and air/diesel downhole steam generators. The degradation of the different alloy components is described in terms of reactions with oxygen, sulfur and carbon in the presence of cyclic stresses, all generated by the combustion process. Recommendations are presented for component materials (alloys and coatings) to extend component lives in the downhole steam generators. 9 … more

Oxy-Combustion Environmental Characterization: Fire- and Steam-Side Corrosion in Advanced Combustion

Description: Steamside Oxidation: A first high pressure test was completed, 293 hr at 267 bar and 670�C; A parallel 1 bar test was done for comparison; Mass gains were higher for all alloys at 267 bar than at 1 bar. A comparison was made with longer-term literature data: Ferritic steels--no consistent pressure effect; Austenitic steels--fine grain alloys less able to maintain protective chromia scale as pressure increases; Ni-base alloys--more mass gains above 105 bar than below. Not based on many data poin… more

Fireside Corrosion in Oxy-Fuel Combustion of Coal

Description: The goal is to develop technologies for pulverized coal boilers with >90% CO{sub 2} capture and sequestration and <35% increase in the cost of electricity. Air-fired power plant experience shows a corrosion loss max at 680-700 C. Low melting point alkali metal trisulfates, such as (K,Na){sub 3}Fe(SO{sub 4}){sub 3}, become thermally unstable above this temperature range. Some overall conclusions are: (1) CO{sub 2} + 30% H{sub 2}O more corrosive than Ar + 30% H{sub 2}O; (2) Excess O{sub 2} … more

Fireside Corrosion in Oxy-Fuel Combustion of Coal

Description: Oxy-fuel combustion is based on burning fossil fuels in a mixture of recirculated flue gas and oxygen, rather than in air. An optimized oxy-combustion power plant will have ultra-low emissions since the flue gas that results from oxy-fuel combustion consists almost entirely of CO2 and water vapor. Once the water vapor is condensed, it is relatively easy to sequester the CO2 so that it does not escape into the atmosphere. A variety of laboratory tests comparing air-firing to oxy-firing condition… more

Oxy-Combustion Environment Characterization: Fire- and Steam-Side Corrosion in Advanced Combustion

Description: Oxy-fuel combustion is burning a fuel in oxygen rather than air. The low nitrogen flue gas that results is relatively easy to capture CO{sub 2} from for reuse or sequestration. Corrosion issues associated with the environment change (replacement of much of the N{sub 2} with CO{sub 2} and higher sulfur levels) from air- to oxy-firing were examined. Alloys studied included model Fe-Cr alloys and commercial ferritic steels, austenitic steels, and nickel base superalloys. The corrosion behavior is … more

GRH 12-01 Fireside Corrosion in Oxy-fuel Combustion Poster 0108

Description: The goals are to: (1) Achieve 90% CO{sub 2} capture at no more than a 35% increase in levelized cost of electricity of post-combustion capture for new and existing conventional coal-fired power plants; (2) Provide high-temperature corrosion information to aid in materials development and selection for oxy-fuel combustion; and (3) Identify corrosion mechanism and behavior differences between air- and oxy-firing.

Materials and Component Development for Advanced Turbine Systems

Description: Hydrogen-fired and oxy-fueled land-based gas turbines currently target inlet operating temperatures of ∼1425-1760°C (∼2600-3200°F). In view of natural gas or syngas-fired engines, advancements in both materials, as well as aerothermal cooling configurations are anticipated prior to commercial operation. This paper reviews recent technical accomplishments resulting from NETL’s collaborative research efforts with the University of Pittsburgh and West Virginia University for future land-based gas … more
