Chapter 39: Backing the mountain and eating the mountain (Part 1)
Gao Pragmatic did a little mental calculation and said in surprise: "Aren't the hundreds of hectares of mountains and forests near Sanshenyuan all attached to other courtyards? Why do I think this income is only slightly more than the rent of a tenant? There is no income from these mountains and forests at all?"
Zhang Jin was stunned for a moment, and asked curiously: "How can there be any income from the mountains and forests? The reason why this land came with such a large forest was because Wang Zhi thought that after dedicating the other courtyard to Emperor Xianzong, maybe occasionally
It can be used as a hunting place. Later, when the master took over, he just thought that with such a large mountain forest, there might be another good place to go. He could build a villa in the mountain to cultivate his mind and character... Could it be that the mountain forest could produce anything else? Master Biao,
We are not hunters, we rely on the mountains and eat the mountains."
You are such a waste of natural resources!
Gao pragmatically cursed in his heart that the people of the Ming Dynasty didn't know anything about agricultural economics. They only focused on farming and planting mulberry trees. It's great to add tea trees. I have nearly a hundred hectares of land in my hand. You can't make money with it?
But after thinking about it, I forget it. People today are no worse than people of later generations in some things, but there are also some things where they simply haven’t even touched the threshold.
In mountainous areas like Mentougou where Sanshenyuan is located, if you want to develop and make money right now, you can only rely on what you eat.
If in future generations you ask what resources are the most famous and abundant here, I am afraid that the first thing that comes to mind is coal.
Mentougou's coal production has been famous for a long time in later generations. Even now in the Ming Dynasty, the Mentougou area also supplies coal from the capital and surrounding areas. However, perhaps due to limited transportation capacity, it is currently only available in some areas closest to the capital.
Carry out mining. There are no signs of mining in the large coal mines such as Changgouyu, Da'anshan, Datai, Muchengjian and other famous coal mines in later generations.
However, Gao Qingshi has just seen a rough map of the mountains and forests affiliated with Sanshenyuan. Not to mention that Changgou Valley and Daan Mountain are a little far away, Datai and Muchengjian are within the forest area of Sanshenyuan!
These two places have been the main mining areas of the Beijing Coal Group for a long time in later generations. Together, the two mining areas can produce more than three million tons of coal annually. Of course, being able to achieve it in later generations does not mean that it can be achieved now, but if
If Gao Qingshi had the ability to mine and utilize it, let alone 10% for future generations, even if he only mined 1%, he would be enough to supply the entire capital.
After all, these days, coal is only used for heating, and coal is rarely used even for cooking - because there is no briquettes yet, only briquettes.
The main reason why Gao Pragmatic is not afraid that he will have no place to sell the coal he mines is because the production of briquettes is actually quite simple. When he was a child, he used to help the family in his hometown and did this "making briquettes".
At that time, he was very interested in the fact that watered coal and soil can be turned into briquettes when pushed out of a stoker. Relying on the curiosity of a child, he carefully observed the structure of the stoker. And it was even more ingenious.
Unfortunately, his coal beater later broke down. It was worthless at that time and had no use after it was broken. After getting permission, he dismantled the coal beater and studied it thoroughly, and even repaired it.
I made several small toys from scrap iron. So how to make this tool does not pose any technical difficulty to Gao Pragmatic.
Of course, even coal mining is still a matter of course, so the coal miner is naturally not in a hurry. Moreover, Gao Pragmatic does not like to waste time when doing things. In his opinion, the preparations for some things can be done at the same time, so he is preparing for mining.
Coal mining, while making preparations for making a briquette briquette beater, one thing that needs to be done is making a coal stove.
The biggest advantage of honeycomb briquettes compared to old-fashioned briquettes is that it increases the burning area, but if burned in the open, a lot of heat energy will still be wasted, so a special coal stove is required.
Coal stoves are very common in later generations, especially in rural areas. They can be said to be everywhere, but in fact, manufacturing them, at least under the conditions of the Ming Dynasty, is still a little bit technically difficult. Coal stoves can be divided into furnace bodies and stoves.
There are five parts: the furnace, the bracket and the ash outlet. The other parts are easy to handle. Only the "inner tank" inside - that is, the furnace, will be a little more troublesome, but it is not difficult for Gao to be pragmatic.
Gao Qingshi remembered that when he was a child in his previous life, there was a cast-iron briquette stove with two iron rings on the stove plate that could be used to match pots of different sizes. This kind of coal stove was the target of his plan.
The inside of the furnace needs to be lined with refractory materials to keep the furnace warm and resistant to burning. Refractory materials have been around since ancient times. The reserves near the capital are not small. It stands to reason that there are many in Mentougou, but I can’t remember where they are. I have to send someone.
Go find it.
There is a twitching grate under the stove, which can be pulled out to pull out the burned briquettes. There is a fire door under the stove. Adjusting the size of the fire door can determine the burning temperature of the stove. When a large fire is needed, open the bottom door
Turn on the air supply to increase the air supply, and the briquettes in the furnace will burn fully. When the fire comes up, you can boil water and cook. When the fire is not in use, close the lower fire door to make the fire burn slowly and save coal.
When burning briquettes and adding coal, you only need to put the coal on top, then close the lid and hook the fire door from below. The burned briquettes will break into ash and leak out from below. Of course, you can also use tongs directly from the fire door.
Clip it out from above.
When Gao Jingshi was a child, his family usually bought loose coal and then processed it into briquettes themselves. Add some yellow mud to the loose coal to act as a bonding agent, add water and mix evenly, and then use it as a coal beater to process it into briquettes.
After forming the briquettes into individual briquettes, take some time to dry them, and then you can use them to make fire, cook, boil water or keep warm, depending on the needs of each household.
This kind of coal will not easily break into ash after burning, but will keep its original shape intact. When adding coal, people usually pinch the coal out of the furnace piece by piece, throw away the burned coal below, and then
Put the burning coal back and add new coal on top.
Sealing the fire is also very particular. For example, if there is no need to use fire for a long time at night, the stove will not be completely sealed. The stove will burn slowly and will neither overburn nor be completely sealed and extinguished. This requires
When sealing the fire, grasp the gap left by the fire cover. If the gap is too large, it will be overburned, and if the gap is too small, it will be sealed. And different seasons are not exactly the same. For example, the airflow is more active in winter, and the coal will burn because it gets more air.
It burns faster, so the fire cover should be covered more tightly at this time. In spring, the temperature is high, the air flow is slow, and the coal is not easy to burn, so the fire cover needs to leave more gaps. If you don't control it well, the stove may go out accidentally.
, you have to relight the stove.
After thinking about it this way, we can find that from coal mining to making coal breakers to making briquettes, plus teaching the skills of using briquettes, Gao Pragmatic believes that it is best to complete them together and then launch them jointly, so as to form a synergy at one time
, quickly open and occupy the market.
As for the briquette ash, which can also be used to make cement and be used to repel water in the bottom layer of bonsai, let’s not mention that for now. Cement is of course good, but Gao Wu has too many things to do now, and it is impossible to stop the stall.
The shop is so big, so we can only talk about it slowly.
