Naphtha flare : ウィキペディア英語版
Naphtha flare

Most naphtha flare lamps are forerunners of the nowadays widely known high pressure paraffin lamps such as Coleman, Tilley
and Petromax, They were invented around 1830 and widely used by showmen, market-stall holders, and circuses until World War I, although some were still in use in London markets such as Queens Road up to and during World War II.
Naphtha (a hydrocarbon) became available as a by-product when town gas was produced from coal.
A flare lamp is gravity fed and the fuel evaporates in the preheated burner. The fuel line runs through the burner and when the burner reaches the temperature of everything between 80 and 100 degrees Celsius the naphtha evaporates and gives a flame after the tap is opened. In case the flame goes out, for example by strong wind, the tank runs dry, resulting in a puddle of hydrocarbon on the floor, providing the tap is not closed.
