A portable stove is a cooking stove specially designed to be portable and lightweight, used in camping , picnicking , backpacking , or other use in remote locations where an easily transportable means of cooking or heating is needed. Portable stoves can be used in diverse situations, such as for outdoor food service and catering  and in field hospitals. Since the invention of the portable stove in the 19th century, a wide variety of designs and models have seen use in a number of different applications.
Portable stoves can be broken down into several broad categories based on the type of fuel used and stove design: unpressurized stoves that use solid or liquid fuel placed in the burner before ignition; stoves that use a volatile liquid fuel in a pressurized burner; bottled gas stoves; and gravity-fed “spirit” stoves. The shichirin , a lightweight charcoal stove, has been used in Japan in much the same form since at least the Edo period Most modern Shichirin are made by heating diatomaceous earth , but the raw materials are not uniform.
The shape is mainly cylindrical, square, or rectangular, and the size also varies. Many varieties of shichirin are made for different uses. In North America , they are also known as ” hibachi ” or “hibachi-style”. Early European portable stoves burned animal fat and polar explorers continued to use blubber as a supplement for cooking fuel into the early 20th Century.
Modern portable stoves emerged from the midth century.
Optimus gasoline-burning compact stove
Claims priority, application Sweden Dec. The invention is concerned with a cooking appliance of this type in which a casing houses the gas container and, when the appliance is not in use, also the burner and associated parts which are arranged on a pivotable support which is swung out when the cooking appliance is to be used so that a cooking vessel can be placed thereon. The object of the invention is to permit the use of a gas conduit of an essentially rigid material between the gas container and the burner without necessitating special couplings in order to permit the above-mentioned swinging movement of the support.
Such couplings are unsuitable in connection with a gaseous fuel stored under pressure since they may easily cause leakage.

The Primus stove, the first pressurized-burner kerosene paraffin stove, was developed in by Frans Wilhelm Lindqvist , a factory mechanic in Stockholm. The Primus No. A steel top ring on which to set a pot is held above the burner by three support legs. Other Primus-style stoves may be larger or smaller, but have the same basic design. The No. The tank, about 3. To light the stove, the user pours a small amount of alcohol into a circular “spirit cup” just below the burner and lights it to heat the burner assembly.
When it is hot, the user pressurizes the tank by means of a small hand pump integrated into the housing, which forces kerosene from the tank up through the rising tube A and the ascending pipe B to the pre-heated burner head C , where the fuel is heated and vaporized. 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. The user can pump the tank more to increase the pressure and make the flame larger; turning a small “air screw” usually located in the filler cap will release pressure from the tank and make the flame smaller. If no alcohol is available for lighting, a twist of cloth or even dry grass will form a wick in the spirit cup.
Pumping once will dispense a small amount of kerosene to dribble down into the cup which will then light using the wick.
