Why did the countryside slowly ban the use of earthen stoves ?

"Clay stove" cooking in our country has a cultural tradition of thousands of years, the ancients and modern people have always used "clay stove" to cook, one is simple and convenient, the use of free straw everywhere to ignite the fire, the meal made is very fragrant, especially in the northeast, the fire kang is connected to the "clay stove". Therefore, the vast majority of rural households use earthen stoves for cooking, instead of gas canisters or natural gas. Presumably everyone who was born in the countryside is no stranger to the earthen stove, we grew up eating the food cooked by the earthen stove when we were young, although now we have grown up, but the scene of cooking on the fire is forever sealed in our memory.

<> with the development of the rural economy and the relatively large environmental protection efforts in rural areas, the construction of new rural areas has become more and more intuitive, and many rural areas no longer use "earthen stoves" for cooking. Of course, there are still some places that may exist. As we all know, using earthen stoves for cooking requires leaves, branches, corn stalks, etc. as fuel, and these items will produce smoke and a large number of floating particles when burned, affecting air quality and people's health.

Therefore, the use of "earthen stoves" in rural areas began to be slowly banned. <>

In addition to the use of earth stove in addition to a large number of dust particles floating in the air, affecting the health of farmers, the use of earth stove is difficult to make the fuel fully burned, will produce a large amount of exhaust gas, pollute the environment, in winter, the indoor space is relatively closed, with the earth stove fire cooking will have potential safety hazards. <>

Although the use of "earthen stoves" in rural areas has been slowly banned, the state has already made plans. Now many rural areas are connected to natural gas, natural gas can not only cook but also heat and boil bath water, the main thing is that it is cleaner and more hygienic than earthen stoves, and safe, natural gas may be popularized to more rural areas in the future, and natural gas is generally subsidized in rural areas. In addition to natural gas, electricity prices in rural areas are also cheaper than in cities and towns, and in some places it is half price.

Electric cookers, induction cookers, etc. can be used at home, and electric stoves are more worry-free. The ban on "earthen stoves" is actually a good thing for the rural environment, although you can't see the previous misty cooking smoke, that kind of rural beauty, but in exchange for a clean and hygienic new countryside is also good.

The reason why it is forbidden to use clay stoves is because the use of clay stoves will easily cause environmental pollution.

This is due to the country's environmental considerations, believing that they will burn a large number of trees, straw, and sorghum stalks, and the exhaust gases produced will pollute the atmosphere.

The main reason is that if you use earthen stoves, you may need to cut down indiscriminately, so the forest area will be reduced.

It is not to ban the earthen stove, the new stove is better and safer than the earthen stove, and now many families do not burn firewood.

1. Build the foot of the stove (i.e., the air inlet duct).

When laying about five layers of bricks, it can be convex 4 cm outward, and then you can try to put the stove grate. The height and width of the air inlet duct can be taken from the pot.

A quarter of the diameter, the depth is level with the inner end of the grate, so as to facilitate air intake. Most of the lower parts of it are built into a slope type to enhance the effect of wind induction. The inner wall of the air inlet duct should be smooth and seamless to reduce the air inlet resistance.

After the stove base is built, form the first platform, smooth it, buckle the pot on top of it, and the distance from the perimeter is the same as when the first stakeout, then draw a line, and finally take the pot and follow the line drawn.

Buildings. Second, build the stove door. The position of the stove door should be 3 4 cm lower than the smoke outlet, if it is higher than the smoke outlet, the smoke will not go well. Generally, it is 12 cm higher and 14 cm wider than the stove door, and the wood-burning stove door can be larger.

It is better to make the stove door smaller without affecting the firewood. The two bricks on and below the stove door are easy to break, try to find good bricks. If it is a double-pot stove, for the level of the stove surface, and also for the height of the hanging fire (because the depth of the small pot is shallow than the depth of the large pot), the small pot stove door should be 6 12 cm higher than the large pot stove door.

3. Build a combustion chamber (also a stove).

At this time, you should find the center point of the grate, so that the navel of the pot is aligned with the grate. The installation position of the rear pull wind stove grate is centered on the navel of the pot, and the total length of the grate is 1|5~1|3 towards the chimney, 4|5~2|3. With the back to the chimney, the installation angle of the grate is tilted 12———18 degrees from the outside to the inside. The grate at one end of the door is higher than the other end inside the hall. The grate of the front pull stove can be laid flat.

The grate can deviate slightly from the navel of the pot and should be offset to the side of the wall. The height of the masonry should consider the depth of the pot and the height of the hanging fire. The height of the fire should not be too high, otherwise the pot will not be fully heated.

Fourth, the smoke outlet.

The cross-sectional area of the smoke outlet is slightly larger than the effective area of the grate. The empirical size width is equal to or slightly greater than the width of the stove door and the height is about half the width of the stove door. The smoke outlet should be located at the highest point of the stove, close to the bottom of the stove top. Its upper edge is generally 3-4 cm lower than the top of the pot.

Fifth, build the stove. Usually the cooktop is built so that the stove protrudes 4 8 cm. When building the stove, you should also pay attention to leaving 3 4 cm from the inner mouth to make the side of the pot. Wire reinforcement should be applied.

6. Wipe the sides of the pot. Generally, the thickness of the edge of the pot is 25 30 cm, and the edge of the pot should be tight and not leaking.

7. Build chimneys. The height of the household chimney is about three meters. In general, the chimney should be raised above the ridge of the roof.

Rice. A ram should be set at the appropriate position of the chimney to control and adjust the exhaust volume of the chimney. The inner diameter of the outlet of the chimney is 12-18

Centimeter. 8. Painting.

The key is in the chimney, because the chimney not only smokes, but also the more important thing is to pull out the fire, and whether it is done well determines the firepower. Seeing that it makes sense, it's best to inquire around and seek help from insiders.

There are four walls, which are like rooms without a roof, and one of them is like a doorway.

Make a pyramid out of mud and hollow it out.

This problem is solved.

oil smoke; Raid.

According to the decades of experience of the older generation, there is no better solution to the problem of oil smoke;

First of all, it is wood-burning, there is an open flame, and the smoke and dust brought by the open flame combustion are not easy to be absorbed by the machine after they are dispersed, which will seriously reduce the service life of the machine;

In fact, as long as there is an independent room, you don't have to care about the problem of firewood smoke, such as gas smoke in the community, there is no smoke after the smoke is dissipated, and there is basically only oil, so if there is no range hood after a month or two, it will be greasy everywhere, and it will be very unpleasant to touch.

However, have you found that on the earthen stove in the countryside, because of the burning of firewood, the firewood produces smoke and dust, mixed with oil, but it is not as serious as the problem of oil smoke in the city, except for some oil smoke problems near the earthen stove, which produces hehehe putty, and the walls are blackened, there is no greasy problem in other places, and the furniture walls are not sticky to the touch, but the walls are still very dry, which are the reasons for the fire;

Therefore, make a smoke window smoke exhaust, regularly clean up the ashes under the furnace, live in the countryside for more than 10 years, never been troubled by the problem of oil smoke, but now live in the community room, the living room and the kitchen are connected, the range hood is broken in that week, there is a lot of trouble, the whole living room is covered with a layer of oil, from the book to the sofa, which oil, hey, it is really uncomfortable, in the problem of oil smoke, never felt that the rural earthen stove is good at that time!

The problem is to solve the problem of oil smoke; Raid.

According to the decades of experience of the older generation, there is no better solution to the problem of oil smoke; dao

It would be better to find a suitable ventilation location above the earthen stove and install an exhaust fan.

Clay stove, make a chimney, let the chimney extend to the roof or outside the house, but the chimney of the wood stove needs technical content, the function of the chimney can be smoking, exhausting smoke, destroying fire. If you don't do it well, the smoke can't be discharged, but it will lead to black fire. You might as well go to a master who can make muddy water to find out.

First of all, the ventilation of houses with earthen stoves is particularly good;

Secondly, the earthen stove has its own blower, such as a chimney;

Again, the oil of the inner past.

Rong is all natural extraction, almost no chemical emissions

Of course, if you're in today's society. It is good to have windows, mainly to be transparent; The stove should be done well, there is not much smoke for burning firewood, and more than 70% of the smoke can be discharged from the chimney; As for the fumes of stir-frying, if it is a light diet, there is not much of a problem.

It's possible that your exhaust is in the wrong direction, and the wind outside the house is just blowing against the window. You'd better install a hollow tube with a diameter of 300mm on the stove to let the smoke out of the tube.

Make a hole in the wall.

Pull a socket. Go to the market or buy a ventilator at a place that sells hardware to get out the fumes.

How to smoke from the earthen stove used in the countryside.

1.Littering fuel.

Most of the fuels used in rural earthen stoves are firewood, straw and cow dung, etc., which are flammable substances, and if the fuel is placed indiscriminately, once the sparks or fire are splashed, it will cause fires and cause serious consequences.

2.The stove is not cleaned.

Because most of the fuel used in rural earthen stoves is straw and cow dung, these debris are easy to accumulate in the stove, and if they are not cleaned for a long time, they will lead to carbon accumulation on the inner wall of the stove, which not only reduces the combustion efficiency, but also may cause fires.

3.Leave the stove while the food is cooking.

The fire power of the rural earthen stove is relatively large, and you must take care of the whole process when cooking food, and do not leave the stove for no reason to avoid accidents.

4.Use of low-quality cooktops.

Most of the materials of rural earthen stoves are stone, loess and bricks, etc., and if you use inferior stoves, such as air leakage, it will pose a threat to personal safety.

5.Don't pay attention to the heat when cooking food.

The heat of the rural earthen stove is difficult to control, and if you do not pay attention to the heat, it is easy to cause gas poisoning and scalding.

6.Throw manure at will.

Most of the fuel for the earthen stove in Nongshoutdou Village is organic matter such as cow dung, and if the manure is thrown at will, it will not only affect the sanitary environment, but also may lead to pollution and affect health.

7.Put a lot of straw fuel.

It is relatively common for rural earthen stoves to use straw as fuel, but if too much straw is put in at one time, it is easy to cause fires.

8.Fuel is placed on the ground.

Perhaps it is convenient to be careless when placing fuel, which can lead to disaster. Putting fuel on the ground is not only greasy, but it is also easy to be covered with tree branches, and the fuel on the ground can also cause fire or burn spillage, which is extremely dangerous.

9.The fuel ignites the closer obstacles.

Rural earthen stoves are often used outdoors, and there will be some straw or wood branches around the stove. If the fuel is placed directly near these debris at the time of ignition, it will cause a fire.

10.Clean the stove from time to time.

If the stove is not cleaned regularly, it is easy to cause carbon deposits, and it will also affect the quality of life and cause health hazards.

The earthen stove of my childhood is indeed very earthy, and it is made of mud and stones, and even the chimney is effectively made of bamboo and an iron cage is covered with mud. At that time, there was little firewood in the mountains, in order to better save firewood, a wooden expansion tank was assembled next to the stove, and the basic principle of the fan of the expansion tank was used to improve the fire point and save firewood. The cooktop is made of mud and is very easy to get dirty.

But the earthen stove is every child's favorite, every time the stomach is hungry or the mother is cooking in the pot, they will climb up the expansion tank, and see the mother make a good meal, the smell of the vegetable will make people unconsciously discharge saliva.

Count with your fingers, there are 8 months of time a year, you must make a fire Kang, spring, autumn situation, the soil kang is a little network hotspot, the colder the temperature, the hotter the soil kang will be, to the case of three or nine days, the soil kang will burn the thief lala hot, the countryside in the northeast is the house in the cold soil kang hot, in short, sleep at night to drill into the bed, the bed is hot. 's body is not cold, and you can sleep soundly this night! In the mountainous countryside or in the plains, the traditional earthen stove is still flourishing.

It is said that the application of earthen stoves is less, which is also for young people and areas lacking firewood, young people because of the simplicity of the province, love to clean up, and more than half of their daily life in the big city is accustomed to gas stoves, not used to the traditional earthen stove cooking, even if they return to the countryside will buy gas stoves to cook rice, so of course the earthen stove is less used. There are also two defects in cooking rice with an earthen stove, one is that the smoke and fire are not hygienic, especially the firewood and dust, which is a difficult hurdle for young people who love cleanliness.

The second is to cook rice with a wood stove, the ambient temperature can not be controlled, if there is no long-term work experience, the food is not half-cooked or overcooked, eat the best appetite. There is an urgent shortage of firewood for earthen stoves. I remember when I was a child, one of my jobs was to go out into the mountains and forests after school to collect firewood.

Now, on the one hand, after the closure of the mountain and the forest, Yang Ting can no longer harvest at will, on the other hand, the family is basically full of elderly people and children, and no one goes to collect firewood. Without the requirement to burn clay stoves, there would be no one to collect firewood.
