Gao Jingshi 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? These mountains and forests have no income 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 there might be another good place to go in such a large mountain forest. He could build a mountain villa 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 to survive."
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. You can't make money with the nearly one hundred hectares of land in my hand?
But after thinking about it, I forgot about 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, mining is currently only carried out in some areas closest to the capital. There are no signs of mining at the Changgou Valley, Da'anshan, Datai, Muchengjian and other large coal mines that will be famous 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 future generations definitely does not mean that it can be achieved now, but if Gao Pragmatic has the ability to mine and utilize it, let alone reaching 10% in future generations, even if the mining volume is only 1%, he will 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 coal and soil poured with water 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. What's even more coincidental is that his coal beater later broke down. At that time, this thing was already worthless and had no use after it broke. So after getting permission, he dismantled the coal beater and studied it thoroughly. , and even made a few small toys out of scrap iron. Therefore, there is no technical difficulty for Gao Pragmatics on how to make this tool.
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. While preparing for coal mining and manufacturing briquette coal beaters, one thing that still needs to be done is manufacturing coal stoves.
The biggest advantage of 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 needed.
Coal stoves were very common in later generations, especially in rural areas. They were everywhere, but in fact, manufacturing them, at least under the conditions of the Ming Dynasty, was still a little technically difficult. Coal stoves can be divided into five parts: the furnace body, the furnace table, 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. Highly pragmatic.
Gao Pingshi 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 grate under the stove that can be pulled out to pull out the burned briquettes. There is a fire door at the bottom of 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 lower furnace door 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 cover the lid, and when the fire door is hooked from below, the burned briquettes will break into ash and leak out from below. Of course, you can also use tongs to pinch it out from above.
When Gao Jingshi was a child, his family usually bought bulk 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, then you can use it as a coal beater to process it into honeycomb briquettes. After making individual briquettes, they can be used 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 take the coal out of the furnace piece by piece, throw away the burning coal below, then put the burning coal back, and add new coal on top.
Sealing 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 a good grasp of the gap left by the fire cover when sealing the fire. If the gap is too large, it will be over-burned, and if it is too small, it will be sealed. And different seasons are not exactly the same. For example, in winter, the airflow is more active, and the coal will burn faster because it gets more air, so the fire cover should be tightly covered at this time. In the beginning of spring, the temperature is high, the air flow is slow, the coal is not easy to burn, and the fire cover needs to leave more gaps. If you don't control it well and the stove goes out accidentally, you will have to relight it.
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 opened and occupied the market.
As for the briquette ash, which can also be used to make cement, and for the bottom layer of bonsai to repel water, let’s not mention that for now. Cement is of course good, but Gao Wu has too many things to do at hand, and it is impossible to stop the stall. The shop is so big, so we can only talk about it slowly.
