  2. Thermal oxidation - Wikipedia

    en.wikipedia.org/wiki/Thermal_oxidation

    Furnaces used for diffusion and thermal oxidation at LAAS technological facility in Toulouse, France. In microfabrication, thermal oxidation is a way to produce a thin layer of oxide (usually silicon dioxide) on the surface of a wafer. The technique forces an oxidizing agent to diffuse into the wafer at high temperature and react with it.

  3. Thermal oxidizer - Wikipedia

    en.wikipedia.org/wiki/Thermal_oxidizer

    Direct-fired thermal oxidizer using landfill gas as fuel [3] Regenerative thermal oxidizer (RTO) sized for 17,000 standard cubic feet per minute (SCFM). Control center with a programmable logic controller for a RTO. The simplest technology of thermal oxidation is direct-fired thermal oxidizer.

  4. Ultra-high-purity steam for oxidation and annealing - Wikipedia

    en.wikipedia.org/wiki/Ultra-high-purity_steam...

    Also, thermal management of the heat profile of the furnace and incomplete combustion affect furnace performance. In selective oxidation processes, water vapor is needed with hydrogen and without molecular to oxygen. This allows for the oxidation of specific metals.

  5. Heat treating - Wikipedia

    en.wikipedia.org/wiki/Heat_treating

    Heat treating furnace at 1,800 °F (980 °C) Heat treating (or heat treatment) is a group of industrial, thermal and metalworking processes used to alter the physical, and sometimes chemical, properties of a material.

  6. High-temperature corrosion - Wikipedia

    en.wikipedia.org/wiki/High-temperature_corrosion

    High-temperature corrosion is a mechanism of corrosion that takes place when gas turbines, diesel engines, furnaces or other machinery come in contact with hot gas containing certain contaminants. Fuel sometimes contains vanadium compounds or sulfates, which can form low melting point compounds during combustion.

  7. Basic oxygen steelmaking - Wikipedia

    en.wikipedia.org/wiki/Basic_oxygen_steelmaking

    Filling the furnace with the ingredients is called charging. The BOS process is autogenous, i.e. the required thermal energy is produced during the oxidation process. Maintaining the proper charge balance, the ratio of hot metal from melt to cold scrap is important. The BOS vessel can be tilted up to 360° and is tilted towards the deslagging ...

  8. Claus process - Wikipedia

    en.wikipedia.org/wiki/Claus_process

    This is a strongly exothermic free-flame total oxidation of hydrogen sulfide generating sulfur dioxide that reacts away in subsequent reactions. The most important one is the Claus reaction: 2 H 2 S + SO 2 → 3 S + 2 H 2 O. The overall equation is: [5] 2 H 2 S + O 2 → 2 S + 2 H 2 O. The temperature inside Claus furnace is often maintained ...

  9. Carbothermic reaction - Wikipedia

    en.wikipedia.org/wiki/Carbothermic_reaction

    A prominent example is that of iron ore smelting.Many reactions are involved, but the simplified equation is usually shown as: 2 Fe 2 O 3 + 3 C → 4 Fe + 3 CO 2. On a more modest scale, about 1 million tons of elemental phosphorus is produced annually by carbothermic reactions. [2]
