Microwave discharge electrodeless lamps (MDEL)
Part IV.† Novel self-ignition system incorporating metallic microwave condensing cones to activate MDELs in photochemical reactions
Abstract
A metallic condensing cone that concentrates microwave radiation (equivalent to an optical lens) has been developed and used as part of a system to activate a microwave discharge electrodeless lamp (MDEL) in the oxidative treatment of wastewaters by aiding the novel self-ignition of the lamp on irradiation at low microwave power levels. This approach to self-ignition can potentially lead to considerable energy savings in such treatments. System performance was examined for the ignition power of microwaves of such MDEL devices in
