Summary
Description Sumburgh Lighthouse Lamp.jpg |
English:
A 85mm
Chance Brothers
Incandescent Petroleum Vapour Installation
which produced the light for the
Sumburgh Head
lighthouse
until 1976. The lamp (made in approx. 1914) burned vaporized
kerosene
(paraffin); the vaporizer was heated by a
denatured alcohol
(methylated spirit) burner to light. When lit some of the vaporised fuel was diverted to a
Bunsen burner
to keep the vaporizer warm and the fuel in vapor form. The fuel was forced up to the lamp by air; the keepers had to pump the air container up every hour or so. This in turn pressurized the paraffin container to force the fuel to the lamp. The "white sock" is in fact an unburnt mantle on which the vapor burned.
