The simplest technology of thermal oxidation is direct-fired thermal oxidizer. A process stream with hazardous gases is introduced into a firing box through or near the burner and enough residence time is provided to get the desired destruction removal efficiency (DRE) of the VOCs. Most direct-fired thermal oxidizers operate at temperature levels between 980 °C (1,800 °F) and 1,200 °… WebbThermal oxidation of silicon surfaces is usually performed at high temperatures (800 C - 1200 C), resulting in a High Temperature Oxide (HTO) layer. The ambient environment can either be ``wet'' using water vapor or steam, or ``dry'' using molecular oxygen as the main oxidant. The reactions which take place during wet and dry thermal oxidation are
WebbFor identical thermal oxidation temperature fibres graphitized at low temperatures exhibited higher reactivity. The induced structural defects (i.e. higher sp3 content and oxygen containing functional groups on the surface) facilitate the adsorption of the active species, which, in turn, accelerates the charge-transfer kinetics.
WebbWe took a close look at the thermo-oxidation behavior of Arnitel®, a polyester-based thermoplastic elastomer (TPC) commonly used to replace rubber in under-the-hood applications. This class of materials is generally limited to continuous use temperatures of 125°C after stabilization.
