The use of gas burners for cooking on a hiking trip is quite justified, appropriate and quite practical. Significantly time is saved and there is no need to prepare firewood and make a fire, as well as to make fire devices.
Disadvantages and disadvantages of compact gas burners on hiking trips, overview and thoughts.
By manually adjusting the intensity of the burner flame, it is possible to achieve the temperature regime necessary at the moment for cooking. In addition, a gas burner will help out in low-forest areas or areas where bonfires are prohibited. If you go on a camping trip together, or are going to cook in groups in a big company, a gas burner is a very good choice both in terms of convenience and in terms of ecology. A bonfire will simply become a cozy addition to the soul and a place of common gatherings.
Unfortunately, the use of gas burners in the campaign has its drawbacks, which mainly relate to the gas cylinders used with them. We will try to list them.
1. Volume and weight of gas cylinders for gas burners.
Due to the fact that modern gas cylinders make it possible to refuel them again after the gas mixture in them is completely consumed, they can be classified as equipment that is constantly with you. That is, as you put them in your backpack at the beginning of the trip, you will most likely bring them back. The volume of space occupied by them in the backpack does not change, only their weight decreases as the gas mixture is consumed. For example, with a three-time diet, the average gas consumption is 70-80 grams per day per person in the summer and 100-140 grams (depending on the conditions, sometimes more) in the winter. Therefore, going together on a three-day trip and relying only on gas, you will have to carry at least 480 in the summer and 840 grams of gas in the winter, which will weigh 0.843 and 1.29 kg in cylinders, respectively. While occupying a constant useful volume of a backpack of 1.7 liters and 2.6 liters, respectively.

2. The influence of the environment on the operation of gas burners.
At low temperatures, as a result of cooling the gas mixture, the burning rate of gas burners is significantly reduced. A gas cylinder requires additional thermal protection in the form of a cover, and sometimes in order to start a gas burner it is necessary to heat the cylinder with dry alcohol. In addition, at low temperatures, the quality of the gas is very important. The wind is able to blow out all the heat of the flame or extinguish it, so the burner itself needs additional wind protection.
3. Limit on the number of gas burners fed.
No matter how powerful the gas burner is, cooking on it for more than 3-4 people is quite problematic. If the volume of water exceeds 2-2.5 liters, the boiling time increases significantly and this greatly delays the entire cooking process. Especially in the cold season, since the pot loses heat through its side walls, due to the lack of a lid, and also because of its shape. The lid is necessary, the boiler without it loses heat faster than the burner heats it.
If we turn to the school physics course, it is known that half of the energy is spent on bringing water to a temperature of 80-90 degrees, and the second half on heating from 90 to 100 degrees. Therefore, it is possible to heat water in a large volume, but it may not be possible to boil it at low temperatures. For large boilers, it is possible, in principle, to adapt and use two or even three burners placed side by side. But then the gas consumption will be super-huge and it will be necessary to provide for wind protection, which is not always possible.
4. Risk of gas cylinder explosion.
The probability of such a case is extremely small, but still exists. Mainly due to violation of elementary rules of operation and safety, cylinder corrosion, mechanical shock, exposure to high temperatures and open flame.
5. Cash costs for the purchase of gas cylinders.
An important, if not the main minus. Modern gas burners are quite durable and the cost of their purchase is justified, gas cylinders are another matter. The cost of new 220 gr. from 6 c.u., 450 gr. from 11 cu, and their refueling will cost about a third of their cost.
Taking as an example the above example (2 people for 3 days), we have only gas costs in the amount of, in summer, from $ 15 and in winter from 20 cu After refueling, the numbers will be slightly less, but the number of recharges is limited, so soon you will have to buy new gas cylinders again. It’s good if you go out into the countryside once a year, and if once or twice a month, and even for a few days each time?
