The amount of kerosene evaporated and heat generated can be increased in direct proportion to the area of the contact surface between the kerosene and air. The wick used in a kerosene heater consists of many bundles of fine fibers and, in accordance with the principle behind it, it is designed to provide a large evaporation area.

When the lamp is lit, the kerosene that the wick has absorbed burns and produces a clear, bright, yellow flame. As the kerosene burns, capillary action in the wick draws more kerosene up from the fuel tank. All kerosene flat-wick lamps use the dead-flame burner design, where the flame is fed cold air from below, and hot air exits above.
Evaporation is a phase transition from the liquid phase to vapor (a state of substance below critical temperature) that occurs at temperatures below the boiling temperature at a given pressure. Evaporation occurs on the surface. Evaporation only occurs when the partial pressure of vapor of a substance is less than the equilibrium vapor pressure ...
That's why, when winter hits and the air outdoors becomes too cold and dry, investing in a humidifier is a great option for increasing the humidity level indoors. The way in which the moisture is ...
The kerosene vapour is then forced under pressure through the descending tube (D) to the vapor nozzle (E); here it sprays through a jet in the middle of the burner, where it mixes with air and burns in a sootless blue flame. The heat from that flame vaporizes more fuel to sustain the process when the spirit cup burns out.
