Retkikeitin

A retkikeitin, or camp stove, is a small portable stove intended for cooking outdoors during camping, trekking, or other outdoor activities. It is designed to be compact and lightweight, so it can be carried in a backpack. Most retkikeittins are fueled by either gas canisters (such as isobutane/propane mixtures) or liquid fuels (such as white gas or kerosene), while lighter varieties may burn alcohol or solid fuel.

Common types include gas canister stoves, which are popular for their quick setup and easy ignition, and liquid-fuel or multi-fuel stoves, which can burn a range of liquids. There are also ultra-light alcohol stoves and compact solid-fuel stoves for minimalist use. A typical stove consists of a burner, a regulator or valve to control flame, and pot supports, sometimes with a built-in or optional windscreen and a piezo or match ignition.

Operation involves releasing fuel to the burner and lighting it, with flame control allowing simmering or rapid boiling. Many models are designed to be stable on uneven ground and to minimize heat loss with wind protection. Boil times vary with stove type, pot size, and fuel, but retkikeittins are generally optimized for fast heating and efficient fuel use.

Considerations when choosing a retkikeitin include weight, fuel availability, boil time, performance in cold or high altitude, and how easy it is to use and maintain. Safety concerns include keeping the stove on a stable, nonflammable surface, ensuring proper ventilation, and following local disposal rules for empty fuel canisters.
