How to use outdoor cooking utensils safely when camping
Stoves are essential equipment for hiking in the mountains. A suitable stove allows the carrier to have a good meal after a tiring day of climbing, which will make you feel very happy. So how do you choose outdoor stoves? Let's take a look.
Introduction to outdoor camping stoves
Stove is a kind of burning device, and burning is a kind of fierce oxidation. Any substance must be converted into gas before it can burn smoothly. To have intense combustion, there must be a large amount of combustible gas, which will naturally turn into gas when it is released from the fuel tank. Therefore, it does not need a vaporization device under normal circumstances; but fuels such as kerosene and gasoline are liquid at room temperature. If it is liquid under normal pressure, the vaporization device is very important, and its design directly affects the combustion capacity and operating performance of the oil furnace.
Therefore, roughly speaking, stoves are divided into gas stoves using gas fuels, kerosene stoves using liquid fuels, gasoline stoves, and alcohol stoves. The fuels used include kerosene, gasoline, alcohol, and liquefied petroleum gas, among which propane and butane are the main fuels.
Which includes in camping stove?
Gas stove, one of the most common stoves on the market, fuel: used with gas tanks, the fuel is mainly liquefied petroleum gas which is liquid when carried, and needs to be gasified into gas when used.
Advantages：1. Combustibles are most active in the state of gas, and can be combusted in a controlled and safe manner;
- It is small to carry and easy to use;
- There are no excessive requirements for temperature and air flow.
Disadvantage：1. It is difficult to obtain materials. Low temperature conditions will affect the gasification of liquefied gas, which will affect the stability of the combustion adjustment, resulting in a delay in the adjustment of the flame.
- The general standard can basically burn about 4 hours, not suitable for long-period outdoor use;
- Gas tanks are dangerous goods and are not suitable for carrying in public transportation.
Gasoline stove, fuel: Gasoline vapor is produced by gasoline pumping and pressurization which is supplied to the burner for combustion. Theoretically, it uses clean "white gasoline". In actual use, it can also be used with high-grade ordinary gasoline.
1. Firepower and heating power are generally higher than that of gas tanks;
2. Carrying an empty can is not restricted by means of transportation, and fuel can be added after arriving at the destination;
3. Long fuel life, one can could be used continuously for many days.
1. Some gasoline stoves are larger than gas stoves;
2. The ignition process is more complicated than that of a gas furnace, and it is more exciting, requiring preheating;
3. The oil pipe of the oil furnace is easy to be blocked and needs to be cleaned regularly.
Wood stove (coking gas stove), fuel: branches, leaves and even cow dung and other combustible substances, the most primitive and direct life tool. Many have their own blower, which can be connected to a power supply or a power bank.
- There are many items that can be used as fuel and combustible materials such as branches and leaves, and the fuel cost is low.
- It is not controlled by fuel and can be carried freely.
- The volume is larger than gas stoves and oil burners;
- It is easy to produce a large amount of carbon ash, and the ash needs to be handled carefully;
- The combustion is unstable and the windproof effect is poor.
Oil-fired stoves: There are oil-fired stoves, and there are also multi-purpose stoves that can be used for oil or gas, and even burn alcohol and other liquid fuels. Fuel oil includes white gasoline, kerosene and ordinary gasoline, etc., with special oil bottles for use.
Alcohol stoves: can be divided into two types of stoves that burn liquid alcohol and solid alcohol. There are various designs of liquid alcohol stoves, including internal combustion and external combustion; there are primary gasification and secondary gasification; there are pressurized gasification methods and open gasification methods. A variety of alcohol stoves have created the world's largest group of stove enthusiasts and stove DIY market. Lightweight equipment enthusiasts and environmental protection enthusiasts highly respect alcohol stoves.
Solar stove: An absolutely environmentally friendly stove, the weight is not very heavy, but its use requires certain technical support, and different technologies must be applied to different sunlight angles to obtain the maximum thermal efficiency. The disadvantage is that it has a strong dependence on sunshine conditions.
Paraffin stoves: including ordinary candle stoves and outdoor paraffin stoves. In general, this type of stove is more suitable for use as a heat preservation stove, and is not suitable for boiling water and cooking.
Small electric stoves and induction cookers: Outdoor RVs with generators are used more often. They are generally not used due to the need for high-power power support under ordinary outdoor conditions.
Outdoor barbecue carbon stove: relatively heavy, fuel-consuming and not environmentally friendly. Generally used in self-driving and RV camping, ordinary camping is rarely used.
How to choose outdoor camping stoves?
- Consider the choice of stove
In outdoor activities, whether you are eating a feast of Complete Manchu-Han Courses, or just boiling water or drinking hot tea, you will need a reliable and easy-to-use stove. A careful understanding of stove size, characteristics and fuel types will be very helpful in choosing a stove that suits you.
Consider and determine the types of most of your outdoor activities: For example, mountaineering and hiking must have different requirements, and the requirements for high altitude and low altitude are also different.
Choose a stove that can meet your needs: This can be concentrated in the feeling of light weight. Of course I do not oppose corruption.
- Consider suitable materials
Considering important factors such as price factor, burning time and easy availability, decide which fuel is best for your itinerary. Mountain expeditions, remote areas expeditions, the applicability of oil stoves is definitely better than gas tanks, you cannot find an outdoor store in a remote small village, but you can find a gas station on the side of the road.
Consider the characteristics and convenience of stoves. Of course, in some extreme places, cow dung and firewood are easier to find than gasoline, ect. But the premise is that you must have rich experience in wild life.
- Consider your outdoor travel plans
The length of the trip: short-distance activities within 3 days are definitely different from long-distance outdoor expeditions over a week. The food you bring depends on whether you want to eat. A Simple or luxury meal？
According to the number of team members: select stoves and fuels which suits your travel. The stoves and fuels used by single, two, and multiple people must be different. At the same time, analyze the outdoor environment of travel, what temperature will be used for cooking. High-altitude mountaineering or low-altitude hiking; winter or summer, because these factors will affect the characteristics of the fuel and decides different stoves and fuels you must choose
- Consider whether the stove is convenient to store
A stove can be carried separately from the fuel. This is probably not a problem. The vast majority of stoves now use external fuel. From gas tanks to oil bottles, they can be conveniently placed in different places in the backpack to increase storage methods and reduce the chance of damage.
The bracket can be folded. A well-designed stove will consider the size of the stove. A stove with a foldable tripod and bracket will be more convenient to store, smaller in size, and save more space in the backpack.
Precautions for the use of outdoor stoves
- Before using the newly purchased oil furnace, it is best to pour a little fuel into the fuel tank and pour it out after cleaning, so as to prevent the residue left over from manufacturing from clogging the pipeline. Pour out the remaining oil in the oil tank when the oil furnace is not used for a long time, leaving only a small amount of oil.
- Before each activity, check and try to make sure that there is no problem before taking it out. Don’t come back in a hurry or even stop cooking when you are in the field.
- When using, pay attention to whether the ventilation is good. Any appliance with a fire source is very taboo to use in a confined space.
- The wind deflector is a very good stove accessory, which not only shields the wind but also reflects heat to improve the combustion efficiency of the stove. However, it is best not to completely enclose the stove during use. At least one side of the fuel control valve should be opened to prevent the knob of the control valve from burning, the safety valve being flushed, or the fuel tank from overheating and deforming. In addition, two furnaces are often used when cooking in a large pot. At this time, we must pay more attention to this problem.
- Each furnace has its own fuel, which cannot be changed arbitrarily.
If scouring oil is used on the furnace, the furnace body may overheat. If kerosene is used in the lamp core gasoline furnace, the oil delivery capacity of the lamp core will be reduced. If butane is used on the furnace of EPI, the firepower output will be relatively poor. It may not matter if the oil circuit is blocked or the firepower is deteriorated, but the danger of the furnace disintegration or deflagration cannot be ignored.
- When it is raining or severe winter, cooking is usually carried out in the tent. In addition to paying attention to the ventilation problem, it is best to use a wide and shallow container (stove box, pot cover or plate) or a special stable at this time. The plate is placed under the stove, so that not only better stability can be obtained, but also the overflowing fuel and the stove that has caught fire can be quickly withdrawn out of the account when fuel overflow occurs. Stoves that use kerosene or gasoline should be ignited and preheated outside the tent before being moved into the tent for use, so as to prevent the tent from being destroyed by a large fire during ignition. After moving into the tent, keep the evacuation route of the stove unobstructed. If the stove has a safety valve, the safety valve should avoid facing people or flammable materials.
- If the stove is burning, close the fuel control valve (or unscrew the pressure relief valve), and then cover the stove with a large pot or wet towel to isolate the air. In fact, the fire stove has an omen, that is, oil leakage, so you should usually take care of the maintenance of the stove. If you find an oil leakage, you must make sure to repair it before using it.
- The distinction between individual and group stoves depends mostly on the size of the burning steam plate and the durability of combustion. In fact, no matter what kind of stove you use, it is best to match the size of the flame with the area of the bottom of the pot when controlling the fire. In this way, better heat transfer efficiency can be obtained.
- The evaporation of the liquid fuel in the fuel tank can maintain the temperature of the furnace body within a certain range. When the fuel is almost used up, the absorption of heat of evaporation will decrease, and the temperature of the fuel tank will rise sharply. The high heat may have some adverse effects on various stoves as follows: It is easy to cause the lamp core to coking and lose the oil transport function; plastic parts melt; melting the solder causes the furnace to disintegrate.
- No flammable substances are allowed to approach within a radius of 30 centimeters to one meter above the stove. In addition, do not place a pot that is too heavy or too large on the stove. If it is too heavy, it will crush the stove, and if it is too large, it will easily be overturned.
