Why does the newly built wood stove boil water for a long time before it gets hot?

The delicacies of the mountains and seas in the high-end hotels of the city can't eat the firewood rice made by the mother, and the firewood rice brings full memories to the wanderers who go out! I often think of my mother's tears when she choked on the smoke from the burning of the wood in order to cook me a meal she liked.

Wood stoves can be divided into earthen ones, brick and earth combinations and iron sheets, and their shapes can be divided into round, rectangular and square, which can be placed indoors and outdoors. In rural areas, basically every household is using it, but now the earthen and brick ones are basically eliminated because they cannot be moved, and most of them are made of iron sheets.

The slow boiling of water in the newly purchased wood stove is mainly caused by the following reasons.

1) The design of the chimney is unreasonable.

The chimney is an indispensable part of the firewood stove, and a reasonable chimney design can make the flames of the firewood stove evenly distributed and prosperous.

The diameter of the chimney is too large, the ventilation is too large, and most of the flames enter the chimney, and the contact area with the bottom of the chimney is too small, and the boiling time will be prolonged.

The chimney is too low and has no pumping force, and most of the flames in the wood stove are rushing outward, which will cause thick smoke to billowing in the house, which is not conducive to boiling water and cooking.

The chimney of the firewood stove is generally 5-10 cm in diameter according to the size of the stove, and the height is more than 20 cm in the wood-burning stove.

2) The stove of the wood stove does not match the iron pot.

The iron pot is too large, the stove is too small, the contact area of the flame to the bottom of the pot is too small, and conversely, the distance between the firewood stove and the bottom of the firewood stove in the bottom of the pot is too small, and the firewood cannot be added sufficiently, resulting in the flame being too small and producing less heat energy.

There are a lot of firewood and grass in rural areas, and cooking with a firewood stove saves a lot of gas costs, but you must choose carefully when buying a firewood stove.

Since the wood stove is built of bricks and gray sand. The newly built firewood stove has a lot of water, and when boiling water, the water in the stove must be boiled dry in order to heat the water.

Why does the new wood stove boil water for a long time before it gets hot? Because the new bricks, the operating soil, and the water are still used, all the water must be boiled dry. The water in the nest is just starting to get hot. It's a little longer.

Some firewood stoves are indeed boiling water for a long time, but they just can't boil, the first is that this firewood is too small, so the pot is not heated, and then this is this. The tool is very hard to heat up.

The size of the stove is determined according to the purpose of the firewood stove, the height of the person who uses it, and the number of family members。On this issue, I am a child who grew up in the countryside, so I still know more about this and have a lot of say. I remember when I was a child, before the electricity reform began, the electricity bill was still very high, and rural families had not yet used induction cookers and rice cookers, and they used wood-fired stoves for cooking.

There are two kinds of firewood stoves in our house, one is a wood-fired stove for boiling water and cookingThe other is a firewood stove used to cook food for livestock. Because of agricultural production activities, every household in the countryside keeps livestock such as cattle, horses, and pigs. A wood-fired stove for boiling water and cooking rice can not only burn straw and corn cobs, but also coal.

The caliber of this set of firewood stoves is relatively small, because the specific volume of the pot used is not too large, and in addition, adults generally cook in rural areas, so its height is relatively high.

When the adults are busy with farm work, the children need to put a bench underneath to cook。At the same time, if the family has a large number of people, two firewood stoves will be built on the side against the wall, and usually two are common in rural households. One can be used to cook rice, and the other can be used to cook vegetables at the same time.

The wood stoves used to cook the animals were much larger than those used at home, because a large iron pot had to be placed on them. Its main fuel is wood, and when we were young, we were happiest when we were able to bake potatoes in a wood-pyre every time we cooked food for livestock.

Firewood stoves are generally only used in self-built houses in rural areas, first, they can make straw and other materials can be used without waste; Second, they wanted to burn firewood and eat food from firewood, so they built a firewood stove; The third is that the firewood stove is simple to build, which can save a lot of gas bills.

With the development of the times, more and more peasant families will reserve the location of the gas stove when building a kitchen, and also build a firewood stove.

According to the purpose of its use, it can probably be divided into the following types:

1. Rural energy-saving firewood stoves. The wood-burning stove born in the new era has a higher utilization rate and is more energy-saving.

2. Rural firewood stoves. The older generation of earthen stoves made of earth, stone and bricks.

Multifunctional wood stove. A firewood stove that takes into account multiple functions such as boiling water and cooking.

4. Smokeless wood stove. A firewood stove that produces less smoke when burning firewood is a stove with a higher firewood burning rate.

Whether it is easy to use should be judged according to the user's use, for example, some people like to use multi-functional, then the choice of multi-functional wood stove is easy to use.

The size of the exterior of the firewood stove used in rural areas is generally determined by the size of the pot and the number of people in the household, while the size of the inside of the stove, such as the combustion chamber, has been explained above.

Therefore, the actual size of the cooktop should be considered from the following aspects:

1. The height of the cook (the overall height of the stove should be suitable for the height of the cooker, but also the height of the internal combustion chamber);

The usage, quantity, and size of pots and pans (if multiple pots are being used at the same time, the longer the cooktop; The number of pots used and the size of the pots also determine the size and number of holes);

3. The number of family members (the more people, the larger the amount of cooking, and the type, quantity, and size of the pots that need to be used are also different).

Therefore, the size of the wood stove needs to be adjusted according to the usage.

Smokeless wood stoves. This is easy to use when burning firewood stoves that produce less smoke.

The design size of the wood stove depends on the height of the family members, not too tall and not too low.

This should be determined based on the height of the cook, as well as the number and size of pots and pans.

Determine the size according to what the firewood stove is used for, and the size of the rural livestock needs to be larger.

Of course, it is up to you to determine what size you need.

This has to be decided according to the population of the family, and it is better to build a larger one if there are many people.

Chuanzi, which seems to be made of tinplate, is used to boil water in the wood stove, killing two birds with one stone, making full use of energy, and now it should be an energy-saving product.

But isn't the boiling water in it called before? What you are asking about is the one who uses firewood to boil water, it should be called Chuanzi farmhouse, it should be called Chuanzi, but the city should not know what it is called, it should be called a kettle, or buy a bucket for warm water!

We call it here: "tea can", a product of Jiangsu and Zhejiang, Wu Yuli has become a soup can, a triangular place between two pots on the stove, a place to boil water made of space.

The materials are boiled in the kettle, and the ones that are not boiled are directly connected to the basin to wash their faces and feet.
