Who knows the principle of steam lamp?

The steam lamp is an incandescent lamp. They burn fuels such as propane, white gasoline or kerosene to generate heat, which causes the lampshade to glow. The lampshade is a ceramic net that surrounds the flame of the steam lamp. A typical lampshade is shaped like this:

At first, the lampshade was a bag made of silk fibers and soaked in different oxides. For decades, Welsbach

Lampshades have become the standard, using a mixture of thorium oxide, cerium oxide and magnesium oxide.

When the lampshade is installed, light the wire, and the wire will burn out, leaving a fragile ceramic shell, as shown in the figure. Because ceramics contain special chemical components and the ceramic net surface area is large, this lampshade has high efficiency.

So you can find that the steam lamp is very simple. Almost any heated substance will glow. Steam lamps generate heat by burning fuel. Because lampshades can effectively use the heat they receive to generate light, steam lamps use lampshades (for example, instead of lime blocks).
