Abstract: A method for sterilizing medical devices, comprising the steps: producing a plurality of hydrogen surface-mixed diffusion flame; exposing the plurality of hydrogen surface-mixed diffusion flame to the medical devices for a predetermined period of time; and exposing the medical devices to the plurality of hydrogen surface-mixed diffusion flame at a predetermined distance; wherein the hydrogen surface mixed diffusion flame further produces free radicals for further sterilizing of the medical devices.

Abstract: A system for using cool hydrogen flame for destruction of VOCs and odorous compounds comprises an existing exhaust system for an industrial process or a factory. The existing exhaust system comprises at least an exhaust duct or a chimney for exhaust gases. The exhaust gases may comprise of odorous compounds such as DMS, MDSO and other VOCs. The system further comprises at least one burner nozzle for generating a configurable hydrogen surface-mixed diffusion flame. The main by-product from this hydrogen flame is water and free radicals. These free radicals produced during hydrogen combustion are extremely reactive and highly oxidative in nature especially hydroxyl radicals. As such, odorous compounds such as VOCs, DMS and DMSO would easily be destroyed by these free radicals produced during hydrogen combustion.

Abstract: Contaminants from surfaces of temperature sensitive substrates, such as glass substrates are removed by exposing the surfaces to a hydrogen Surface-mixed diffusion flame for a predetermined duration of time. The predetermined duration of time being insufficient to heat up the surfaces substantially thereby causing damage to the temperature sensitive substrates.
