Daming Yuanfu

Chapter 76
Gao Wushi did some mental calculations, and said in surprise, "Aren't the hundred hectares of mountains and forests near Sanshen Garden affiliated to other courtyards? Why do I see that this income is almost a little more than the rent? These mountains and forests have no income at all?"

On the contrary, Zhang Jin was stunned for a while, and wondered: "How can there be any income from the mountains and forests? The reason why this land has such a large forest at the beginning is that Wang Zhi wanted to dedicate 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 something good to do in such a large mountain forest, and he could build another courtyard in the mountain to cultivate his mind... Could there be any output from the mountain forest? Master Biao, We are not hunters, we rely on mountains to eat mountains."

You are so reckless!
Gao Yushi cursed in his heart that the people of the Ming Dynasty didn’t understand agricultural economics at all. They only focused on farming and planting mulberries. It’s amazing to add tea trees. How can you not make money with the nearly [-] hectares of land in my hand?

But after thinking about it, forget it, people in this year are no worse than people in later generations in certain things, but there are also certain things that have not even touched the threshold.

In a mountainous area like Mentougou where Sanshen Garden is located, if it wants to develop and make money right now, it can only rely on what it eats.

If, in later generations, one asks what resources are the most famous and abundant here, the first thing that may come to mind is probably coal.

Coal production in Mentougou 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.The famous Changgouyu, Da'anshan, Datai, Muchengjian and other large coal mines in later generations have not yet been mined.

However, Gao Wushi had just seen the general map of the forests attached to Sanshen Garden. Changgou Valley and Da’an Mountain were a little far away, but Datai and Muchengjian were within the forest area of ​​Sanshen Garden!
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 300 million tons of coal annually.Of course, being able to achieve it in future generations certainly does not mean that it can be achieved now, but if Gao Yushi has the ability to mine and utilize it, let alone reach [-]% in future generations, even if it is only [-]% of the mining volume, he will be enough to supply the entire capital.

After all, these days, coal is only used for heating, and coal is rarely used for cooking—because there is no honeycomb, only briquettes.

The main reason why Gao Yushi is not afraid that his family will have nowhere to sell the coal dug up 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 he did this "briquettes".

At that time, he was very interested in the fact that watered coal and soil could be turned into briquettes when pushed out of the coal cutter. Relying on the curiosity of a child, he carefully observed the structure of the coal cutter.What's more, his family's coal machine broke down later. It was worthless in those days, and it was useless after it was broken. After getting permission, he dismantled the coal machine and studied it thoroughly. , and even made a few small toys with scrap iron.So how to make this tool is not technically difficult for Gao Pragmatic.

Of course, right now even coal mining is still a thing of the past, and coal mining machines are naturally not in a hurry. Besides, high-level pragmatics do not like to waste time. In his opinion, the preparations for some things can go hand in hand. While preparing for coal mines and making honeycomb coal briquettes, one more thing that needs to be done is to make coal stoves.

Compared with the old-fashioned briquettes, the biggest advantage of honeycomb coal is that it increases the combustion area, but if it is burned open, it will still waste a lot of heat energy, 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, it is still a little bit technically difficult to manufacture, at least under the conditions of Daming.The coal stove can be divided into five parts: the furnace body, the furnace platform, the furnace, the support and the ash outlet. Highly pragmatic.

Gao Yushi remembers that in his previous life, when he was a child, there was a cast-iron briquette stove with two iron rings on the top of the stove, which could be used to match pots of different sizes. This kind of coal stove was the goal of his plan.

The inside of the furnace needs to be glazed with refractory materials to keep the furnace warm and resistant to burning. Refractory materials have existed in ancient times, and the reserves near the capital are not small. It stands to reason that there are many in Mentougou, but I don’t remember where they are. I have to send someone go find it.

There is a movable grate under the stove, which can be pulled out to shake off the burnt coal balls.There is a fire door under the stove, and adjusting the size of the fire door can determine the burning temperature of the stove.When a big fire is needed, open the furnace door below 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 coals on top, then cover the lid, and hook the fire door from below, and the burnt briquettes will break into ash and leak from below.Of course, you can also directly use tongs to clamp it out from above.

When Gao Yushi was a child, his family usually bought loose coal and processed it into briquettes by himself.Add some yellow mud to the loose coal to play a bonding role, add water and mix evenly, and then it can be processed into honeycomb coal by using a coal cutting machine.After making briquettes one by one, take a while to dry, and then they can be used to light a fire, and then cook, boil water or keep warm, depending on the needs of each family.

This kind of coal is not easily broken into ash after burning, but will maintain its original shape intact.When adding coal, everyone usually clamps the coal out of the stove piece by piece, throws away the burnt coal below, puts the burning coal back, and adds 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, and the stove will burn slowly, neither will it overburn, nor will it be completely sealed and extinguished.This requires mastering the gap left by the fire cover when sealing the fire.Too big a gap and it will overheat, too small and it will seal.And different seasons are not exactly the same. For example, the airflow is more active in winter, 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, and the coal is not easy to burn, so there are more gaps in the fire cover.If you don't grasp it well, if you accidentally turn off the stove, you have to light the stove again.

After thinking about it in this way, it can be found that from coal mining to the manufacture of coal briquettes, to the manufacture of briquettes, plus the teaching of the use of briquettes, Gao Pragmatism believes that it is best to complete the matching and then jointly launch it, so as to form a joint force at one time , quickly opened and occupied the market.

As for the briquette coal ash can also be used to make cement, as well as for water drainage at the bottom of bonsai, I will not mention that for the time being. Cement is of course good, but Gao Wuzhen has too many things to do now, and it is impossible to make a stand The shop is so big, so I can only speak slowly.
