Sewer gas destructor lamp : ウィキペディア英語版 | Sewer gas destructor lamp
The main purpose of a sewer gas destructor lamp is to remove sewer gases and their hazards. == Background == Biogas forming in sewers via anaerobic digestion can be a potentially foul-smelling and explosive hazard (chiefly due to chemical spills). Unlike ordinary gas lamps for street lighting, the main purpose of sewer gas destructor lamps is to remove sewer gases and their hazards. Joseph Edmund Webb of Birmingham patented a sewer gas destructor lamp. Many of these lamps were installed in the UK in towns and cities including Sheffield, Winchester, Durham, Whitley Bay, Monkseaton and Blyth, Northumberland.〔(Chris LLoyd, ''Northern Echo'' 30 July 2008 ) "Raising a Stink"〕 With a flame generated by burning town gas, sewer gases were drawn from the sewer below and discharged above the heads of passers-by to dissipate odours. The flame in the lamp does not actually generate sufficient thermal energy to combust any of the odour compounds in the air.
