A novel de-rusting method with molten salt precleaning and

May 11, 2021 · The molten salt would adhere and solidify on the samples surface after the precleaning process. An intermediate process between molten salt precleaning and laser cleaning was needed to remove the residual salt. This intermediate process consisted of cooling, a water bath, and drying (as shown in Fig. 3). Fig. 3 Analysis and optimization of concentrated solar power Feb 09, 2021 · In the current industrial CSP plants, tower systems with molten salt as both the HTF and the storage material are the most efficient option with annual efficiency of 17%-18%. 31 On the other hand, the lowest among those technical options is the annual efficiency of linear Fresnel systems with saturated/superheated steam, which is 9%-13%. 37 The tower systems can have higher efficiency

proposed molten salt washing method on the basis of the improved formula. The experiment proved that molten salt above 400 C could clean up the carbon deposi-tion on the surface of the valve within 25min. The new formula of molten salt cleaning could only play an auxiliary role in the removal of scale and rust, and the Design and Development of Additively Manufactured Design and Development of Additively Manufactured Molten Salt to Supercritical CO 2 Heat Exchanger in Concentrating Solar Power Application Tracey Ziev1, Ziheng Wu (Dino)2, Srujana Rao Yarasi2, Nicholas Lamprinakos2, ParthVaishnav3,1, Anthony D.

Pass air over and bubble air under the surface of molten salt at various flow rates. b. Pass pregenerated steam over the salt as a comparison with air. c. Generate steam at the salt surface by adding water to the system to determine the relative heat-extraction characteristics of water.

METAL SURFACE SCALE CONDITIONING - KOLENE

  • Background of The InventionBrief Summary of The InventionBrief Description of DrawingsDetailed Description of Embodiments of The InventionThe conditioning of oxide surfaces or scale on metal surfaces, sometimes referred to as descaling, is desired with respect to the production of stainless steel and superalloy metal strips. While our discussion focuses primarily on metals in strip form, the applicability and value of our invention may be useful for conditioning oxide surfaces or scale in various shapes, geometries, or assemblies other than metal strip; it is not our intention to limit the benefit to only metal strip. Stainless steels are ferrous alloys containing A Characterization Method for Al Recovery from Dross Based
    • AbstractIntroductionExperimental ProcedureMathematical Model of The Recovery ProcessResults and DiscussionConclusionsWhen aluminum or its alloys are melted, considerable amounts of dross are produced. The alloy type and the method used in the production of aluminum products play an important role in the amount of dross that will result as a byproduct. The current needs of the Al industry as well as economic and environmental factors demand the recovery of the pure material that is lost during dross removal by simple and efficient methods that can be applied within the foundry. Most cases of Al recovery employ Mathematical model of the metal mould surface temperature Nov 30, 2015 · @article{osti_22496238, title = {Mathematical model of the metal mould surface temperature optimization}, author = {Mlynek, Jaroslav and Knobloch, Roman and Srb, Radek}, abstractNote = {The article is focused on the problem of generating a uniform temperature field on the inner surface of shell metal moulds. Such moulds are used e.g. in the automotive industry for artificial Parameter Optimization and Effect Analysis of Low Mar 08, 2021 · the paint weight loss during cleaning process, the image method was chosen to calculate the cleaning rate, which is the area ratio of the cleaned surface to the entire surface. The concrete steps of the image method are as follows:1.Crop the photo taken after cleaning and delete the treated area from the specimen; 2. Pulse Plasma Nitriding Improves Surface Treatment, Wear Mar 30, 2021 · However, the process of immersing components in molten salt makes it very difficult to remove the salt from open surface porosity. When gas nitriding is used, the nitriding atmosphere permeates all open pores resulting in the entire component, the surface, and

      • AbstractIntroductionExperimental MethodResults and DiscussionConclusionConflict of InterestsAcknowledgmentA key component in the molten carbonate fuel cell (MCFC) is electrolyte matrix, which provides both ionic conduction and gas sealing. The aim of this work is to investigate the effects of selected operating conditions on the performance of the matrix preparation. Slurries were prepared to produce matrices by the technique of tape casting. The characteristics of the slurries and matrices were examined by laser particle size analyzer, scanning electron microscopy, and BET surface area analyzer. The testing resulPEER-REVIEWED ARTICLE bioresourcesThe utilization of molten salt as a medium for biomass pyrolysis and conversion has never been reported before the 1990s (Sada et al. 1992), although some studies on utilization of molten salts as hydrocracking catalysts have been executed, mainly due to the reactors severity when molten salt is employed (Kudsy and Kumazawa 1999).
