    摘要: A heat transfer component that is resistant to corrosion and fouling is disclosed. The heat transfer component includes a heat exchange surface formed from a chromium-enriched oxide containing material formed from the composition δ, ε, and ζ, wherein ζ is a steel containing at least about 5 to about 40 wt. % chromium, ε is a chromium enriched oxide (M3O4 or M2O3 or mixtures thereof) formed on the surface of the steel ζ, wherein M is a metal containing at least 5 wt. % Cr based on the total weight of the metal M, and δ is a top layer formed on the surface of the chromium-enriched oxide ε, comprising sulfide, oxide, oxysulfide, and mixtures thereof. The top layer δ comprises iron sulfide (Fe1-xS), iron oxide (Fe3O4), iron oxysulfide, iron-chromium sulfide, iron-chromium oxide, iron-chromium oxysulfide, and mixtures thereof. The metal M of the chromium enriched oxide (M3O4 or M2O3 or mixtures thereof) may comprise Fe, Cr, and constituting elements of the steel ζ. The steel ζ may be selected from low chromium steels, ferritic stainless steels, martensitic stainless steels, austenitic stainless steels, duplex stainless steels and precipitation-hardenable alloys.

    摘要: An injector assembly comprising an injector (3) and a wall (1) having an inner surface (2) defining a cavity receiving the injector (3). A peripheral surface portion of the injector (3) and a corresponding portion of the cavity inner surface (2) are configured to inter-engage such that force applied to the injector (3) in a predetermined direction causes mutually oppositely directed reaction forces perpendicular to the applied force which tend to laterally compress the injector (3), for relieving lateral stress within the injector (3). Additionally, an injector (3) for fitting in a cavity of an injector assembly, the injector (3) including an axially extending portion (10) comprising at least two peripheral irregularities in an otherwise substantially regular lateral cross-section.
