Tourist stoves are used in mountain, skiing and other trips. Stoves can work on wood, gasoline, kerosene, dry alcohol, gas. In winter trips, the stoves are also used for heating. There are many designs of tourist stoves for heating only..
Camping stoves, stoves, stoves, stoves for cooking and heating, stove design for cured gasoline.
In forest areas, stoves on wood harvested locally are most suitable. In areas where there is no fuel, primus stoves, portable gas stoves and burners are used. Gasoline used for primus stoves is a very high-calorie fuel, but it needs to be carefully packed, as food can be spoiled if it is leaked. As a container for storing gasoline, plastic, iron and aluminum cans are used..
Recently, some groups of tourists began to use aerosol cans. To refuel a small tourist primus, you need one can with a capacity of 0.3 liters. For the bumblebee primus, you need two spray cans. Used cans are thrown away.
Liquefied gas is a good fuel for tourist stoves, but the mass of containers significantly exceeds the mass of gas contained in it. Gas stoves are preferable for campers on a weekend trip, where the mass does not play a major role. Recently, cured gasoline has become a promising fuel, combining high calorie content and ease of transportation.
Dry alcohol burner.
To cook a small amount of food or warm up during a halt, a small homemade folding burner is used. The consumption of dry alcohol for the preparation of a pot of soup from concentrates is usually limited to 60-80 g. However, tablets of dry alcohol are very hygroscopic and require careful moisture-proof packaging. Otherwise, its consumption may double.
The simplest hearth with a windproof wall.
If there is no burner for dry alcohol, the hearth can be built with stones. Using any concentrated fuel, it is necessary to construct windproof and heat-reflecting walls around the hearth. They contribute to the preservation of heat in the heating zone of dishes.
Tourist camping primus with a lateral location of the tank.
This type of primus has a mechanical device for cleaning the nozzle from the inside and does not need primus needles. When the primus is in working position, there is free access to the gas tank, and if necessary it is easy to cool.
When using a pan with a wide bottom, the flame enters the tank and heats it, although there is a special screen in the working position that closes the tank. Therefore, the rack for the pan must be lengthened, make them extendable.
Using such a stove, you can boil a pot of water in 15 minutes without much hassle. One refueling is enough for an hour of burning. The fuel is ordinary gasoline. A tourist group needs to have 2-3 such primus for cooking.
Tourist Primus “Bumblebee”.
Primus “Bumblebee” works on clean automobile and aviation gasolines. One dressing (650 ml) provides continuous burning of the primus for 3-5 hours. A three-liter kettle boils for 18 minutes. At air temperature not lower than 18 degrees.
To speed up the cooking process under a single pan, it is advisable to put two primus at the same time. In addition, in order to reduce heat transfer to the pan, a protective belt of heat-resistant cloth should be put.
Household primus is used when tourists do not have a Bumblebee primus. The household primus has many shortcomings. The main ones are large mass and high fuel consumption. The disadvantages of household primus are also:
The need for periodic cleaning of the nozzle.
Some inconvenience in its operation.
Loose legs to the body.
To strengthen the fastening of the legs to the body and increase their rigidity to the legs of the primus in their upper and lower parts, it is recommended to weld along a metal triangle.
Alpine cuisine, self-made from primus and pots.
Uncomplicated in the manufacture of high-mountain cuisine can be made on the basis of a tourist primus with a lateral location of the tank. Fire in a primus stove does not go out in any wind, and fuel is consumed more economically. Water in such a kitchen boils twice as fast as usual. For the manufacture of the kitchen, in addition to the primus, we also need aluminum pans with a capacity of 3.5, 2.5, 1.9 liters.
Primus understands. A central hole is drilled in the gas cup so that the cone of the burner is 2-3 mm into the hole. In a pan with a capacity of 3.5 liters, a grid of several rows of holes with a diameter of 5-6 mm is drilled. The rows of holes are slightly longer and higher than the primus tank. The bottom row of holes should be at the bottom of the pan.
In the center of the pot rivet a cup for gasoline. From stainless steel strips 1 mm thick and 10 mm wide make a tripod 80 mm high. Its lower slats should be tightly covered by a cup for gasoline. The entire tripod fits into a circle of such diameter as the bottom of a 1.9 liter pan. All pans are removed, and handles are attached to pots with a capacity of 2.5 and 1.9 liters, as in conventional pots. Only one lid is used – from a 2.5 liter pan.
When assembling the tank with the burner is inserted inside the tripod located at the bottom of the pan with the grill. At the same time, the burner stand enters the hole in the cup, and the tank is located next to the grill. The adjustment knob goes through the hole drilled in the same pan..
For transportation, the entire structure is disassembled. Both the pot and the kitchen cabinet are nested together. In a smaller pot remove the rack, stove, adjusting knob, matches in a sealed package. From above everything is closed with a lid. Dimensions of the kitchen – 210×120 mm. Weight with gasoline – 1300 g.
In order not to smell gasoline, it is recommended to refill the primus before using it. For more reliable operation of the primus, it is recommended to replace the factory rubber seal washer with a home-made, machined from plastic. This will greatly facilitate the adjustment of the flame in the burner..
Kitchen appliance designed by F. Nansen for cooking and heating.
Primus is usually used in skiing and mountain hikes, where it is necessary to extract water from snow or ice for cooking. Under these conditions, complete heat recovery is important. The successful design of stoveware was created by F. Nansen in 1895 while traveling to the North Pole. His kitchen appliance slightly increased the efficiency of the primus.
Nansen at the same time heated the tent and cooked food. For 120 days of the trip, having plenty of hot food and water, he burned only 20 liters of kerosene for two (they had kerosene primus), that is, less than 170 cm3 per day.
For a more complete use of heat, there were three tanks on the primus. Food was prepared in the central, and ice was heated in the upper and side. Flue gases, repeatedly changing direction, repeatedly washed the bottom and side walls of all tanks. They came out practically cold, but contained a lot of water vapor, which condensed on the walls of the tent and sleeping bags. This was a significant drawback of the unit..
Naturally, a similar design of a kitchen unit can be successfully used in our time for cooking on a stove or a gas burner. Something can be easily improved. For example, to make a pipe to remove flue gases and vapors outside the tent.
The furnace for cured gasoline designed by B. Ogorodnikov, the use of the stove for cooking, melting ice and heating.
Using the idea of F. Nansen, the master of sports B. Ogorodnikov offers a variant of a similar apparatus designed specifically for burning cured gasoline and has proven itself in difficult ski expeditions in the Arctic.
Cured gasoline is burned on a grate, offset from the center of the unit. Flames and flue gases pass under the entire bottom of the pan and exit through a hole in the lid into the pipe. Due to this, the moisture in the tent does not condense, which significantly reduces its icing. At the same time, an external tank is heated in which ice or snow is laid.
By the time the first course is ripe, two external tanks of water are ready, which are enough to make tea or coffee. This water is poured into a second pan and set in place of the first. The external tank is removed, and thin rings are mounted in its place, through which heat is transferred to the tent. Additional heat recovery occurs in the pipe.
In this form, but without a pan, the unit can be used for heating. In this case, heat transfer comes from the entire surface of the lid. The unit has a valve to control the height of the flame. For transportation, two pans are inserted one into the other and, together with all other elements of the unit, are put into an external tank.
The main dimensions of the individual elements of the cured gasoline stove are as follows:
The capacity of the pan is 9 and 7 liters with the corresponding diameters of 26 and 24 cm.
The ice melting tank has an external diameter of 40 cm, an internal – 34 cm.
Tank height 17 cm.
Material – preferably stainless steel with a thickness of 0.2-0.3 mm.
The technical indicators of this hardened gasoline stove are as follows. To boil 14 liters (8 and 6 liters in two pans) of water from ice, 600 grams of cured gasoline is needed. Boiling time 100 minutes.
