Cooker
design includes three parts - cooker´s body, a fan and a stable base. Fan
is driven by a monocell battery 1,5 V. The running period of the battery
is from 6 to 10 hours depending on the type of the battery, its age and
requested intensity of the fire. The running period of an alkaline battery,
its age and requested intesity of the fire. The running period of an
alkaline battery is 2 or 3 times longer.
Cooking on the cooker is
very cheap and almost independent on the source of fuel. Cooker is
uncomplicated and foolproof. The design is massive and it is very stable
during even when using a large pot. Compared to the common cookers using
gas or liquid fuel this cooker does not cause any problems with fuel
transportation for example in the aircraft. Servicing is not more
difficult than the servicing of a petrol heating (app. 360 grams + 90
grams batteries) but it is amply compensated by saving the weight of the
fuel.
We
stand the cooker´s body on the stable base and attach the fan from the
side. We use kindling and firewood for setting the fire. After initiating
the flame we turn on the fan to full power output for a very short time.
The intensity of the fire can be controlled by the alteration switch on
the body of the fan. During the cooking it is sometimes necessary to put
the pot off the fire and refill the firewood. Intervals between feeding
the fire depend on the kind of the firewood, the size of the sticks and
the intensity of the flame. One litre of water begins to boil in app 5 to
10 minutes with 1 to 3 feedings of the fire. Total fuel consumption is
very low and the firewood can be found almost everywhere. Wet firewood can
also be used for feeding the fire. The power of the cooker is than lower.
Wind can deflect the flame and thereby decrease the fire´s power.
Therefore it is useful to put the cooker leeward. In case the cooker is
used at a themperature below the freeze point it is necessary to transfer
batteries in your pocket to keep them warm and hold the whole batteries´
capacity.

A pot with 10 to 30 cm in diameter and a content up to
5 litres can be used. Low pots are better in utilization of the energy of
the enrgy of the fire and aluminium pots are better than the steel ones.
Cooker can be packed into pots with inside diameter of 15,5cm and height
of 9 cm, which is for example the size of the Czech army pots.
It is necessary to follow all the safety rules of
making and keeping an open fire during the cooker´s operation. Cooker may
be used only outdoors and on a flame resistant underlayment such as sand,
stone etc. It is necessary to keep adequate distance from any fiammable
object. Children are not allowed to use the cooker without direct guidance
of an adult.
