NOTE - Registration Requirements: As part of theDepartment?s implementationof e-Government, WE ARE REQUIRING THE SUBMISSION OF APPLICATIONS THROUGHGRANTS.GOV. There are several one-time actions you must complete in ordertosubmit an application through Grants.gov (e.g., obtain a Dun and BradstreetData Universal Numbering System (DUNS) number, register with the CentralContractor Registration (CCR), register with the credential provider andregister with Grants.gov). You must complete all the one-time actions in?GetStarted? at www.Grants.gov prior to submitting your initial application.APPLICANTS, WHO ARE NOT REGISTERED WITH CCR AND GRANTS.GOV, SHOULD ALLOW ATLEAST 14 DAYS TO COMPLETE THESE REQUIREMENTS. It is suggested that theprocessbe started as soon as possible.Area of Interest 05 - Surface Modification of Alloys for UltrasupercriticalCoal-Fired BoilersThe implementation of ultrasupercritical boilers requires materials withhigh-temperature creep properties and high-temperature oxidation andcorrosionresistance. New ferritic, austenitic and nickel-base alloys have beendesignedto meet the creep resistance demands but the high operating temperatureposesthe risk of accelerated material degradation in various harsh environments.Both fireside corrosion and accelerated oxidation in the presence ofsuperheated steam are of concern.In a coal-fired boiler, there are oxidizing and corroding environments thatrange from simple gas attack to under-deposit microclimates of complexnature.The gases can be oxidizing, such as mixtures of O2 and SO2/SO3, or a morecomplex mixture including aggressive gaseous compounds such as H2S, HCl,COS,CS2, CO and methyl mercaptan. These later gaseous compounds are usuallygenerated during the substoichiometric combustion of coals when modifiedcombustion systems are implemented for NOx emissions control. Similarly,thesubstoichiometric combustion process generates unburned carbon and pyriticparticulate that based on the hydrodynamics of the fireball may end updeposited on heat transfer surfaces. The deposits can generate variouslocalreducing environments ranging from carbonaceous to sulfidizing and evenlow-melting eutectics that act as a flux on the metal surface. The myriadofaggressive environments dictates a careful consideration regarding thequalityof the surface modified layers.Surface modification techniques provide an alternative to otherwise costlynickel-base materials. The science of thermal spray has evolved in the last15years with the implementation of techniques such as High Velocity OxyFuel(HVOF) that have improved the quality of the applied coatings. Cold sprayisanother emerging technology that combined with nano-size powders canprovideflexibility and economics. Technologies, such as weld overlay andchromizing,are used to ensure that pressure parts are adequately protected from theenvironment in which they must operate. Proposals are invited to optimizetechniques such as those mentioned above for use in ultrasupercriticalboilers,or, to provide other new concepts in protection of high temperature alloysincoal-boiler environments.To link to the master announcement DE-PS26-05NT42472-00, please click thefollowing link:https://e-center.doe.gov/iips/faopor.nsf/UNID/AFDC3E3018D30D1C8525700C005DB010?OpenDocument
