The next morning, Marin and Old Huffman talked about buying coal from a coal mine at home. In this regard, the old Huffman naturally has no objection. But in terms of price, the two sides have differences.
It's not that the old Huffman thought Marin was offering a low price, but that it was too high. The old Huffman felt that since his son wanted it, naturally he would not think of making money. Therefore, he proposed that 1 Charteron coal to 1 shilling's operating cost fee can be. However, Marin is not bad at money and wants to help the family, so he proposed a market price of 2 shillings per Charteron.
The father and the son scrambled, and in the end, it was Mrs. Mary who made the decision-according to the compromise between the father and the son, 1.5 shillings per Charteron. In this way, the family earns some money, and Marin can save a lot of money.
"Marlin, what do you want coal for?" Madam Mary asked curiously.
Right now, firewood is popular in Europe, but not coal. In particular, firewood is popular in European fireplaces. Those who burn coal, it 's easy to poison people at home ... Only in special industries such as metallurgy, coal is used in large quantities.
Thinking of gas poisoning, Marin immediately reminded his family:
"Dad, mom, remember not to burn coal in a closed room!"
"Why?" Madam Mary asked curiously.
"My teacher said that coal burned in a tightly closed room, and it was easy to produce toxic gases, causing people to suffocate and die ..."
"What? Is that so?" Everyone was scared.
Speaking of which, the Huffman Manor now cooks and has switched to coal burning. Even Mrs. Mary has plans to replace wood with coal as a fuel for indoor fireplaces. Now, Marin said that Mrs. Mary was scared.
"It's true that brothers and sisters are still young. Don't burn coal in their room to avoid accidents."
"Uh ---" Mrs. Mary nodded quickly, there was nothing more important than the safety of the child.
"By the way, Marin, can you find a solution to the problem of pulverized coal?"
"Pulverized coal?" Marin didn't understand.
"It's just pulverized coal!"
"Is this a problem?"
"Of course, now everyone burns lumpy coal. Powdered coal, because it is always burned out, is not welcome and cannot be sold. People at the Wiggins Chamber of Commerce only need lumpy coal ..."
Marin wanted to laugh when he heard the old Huffman's complain. In fact, powdered coal burns more completely than lump coal and has a larger contact surface with air.
But a key point is the way people in this age burned fire. For example, later generations of coal will blow coal powder into the furnace. Therefore, the pulverized coal is burned completely and the calorific value is very high.
However, people in this era burned coal with a shovel. With a shovel, the pulverized coal was thrown into the hearth, which easily covered the coal that was originally burning. If the pulverized coal covers the previously burning coal, it is easy to isolate the air and cause the burning coal to extinguish.
The coal block is different. There is a large gap between the coal block and the coal block. Therefore, there is a large gap between the shovel shovel and the previously burned coal and the newly added coal. Therefore, there is no fear that coal will go out.
Therefore, the ancients preferred coal nuggets rather than coal powder. Even in modern times, pulverized coal requires professional blowers to blow into the furnace to make full use of pulverized coal.
In the folk, the common people still used coal. However, many of the coal mined in coal mines are pulverized coal. So everyone came up with a way to process pulverized coal into blocks.
Thus, briquettes were born. Briquettes are spherical coal lumps made by mixing pulverized coal with water and yellow mud. In this way, pulverized coal becomes lump coal and can be easily burned again.
Of course, there is a more advanced way-honeycomb coal ...
Briquette combustion, because the contact surface is not enough, the combustion utilization rate is low, and the combustion is not complete. The emergence of honeycomb coal,
The efficiency of coal combustion has been greatly improved.
There are more than a dozen holes in a piece of honeycomb. The walls of these holes are the contact surfaces of coal and air. Honeycomb coal has greatly improved the combustion efficiency, and has also increased the degree of coal combustion. Because briquettes often burn incompletely, resulting in wasted fuel.
Marin thinks that the honeycomb coal thing is easy to use. However, there is no need to promote honeycomb. This thing is for home use. Selling honeycomb coal cannot be much more expensive than briquettes. Now that he is a local tyrant, there is no need to pursue burning efficiency, and it is nothing to waste.
Therefore, Marin directly asked the old Huffman to use the ancient "coal shaking" method he saw in his previous life to process the coal powder into briquettes and sell them.
As for how to shake the briquettes, this is easy. Marin personally showed the workers the technique of "shaking briquettes". Just mix the coal powder, water and yellow mud together and stir into a paste. Then, cut into pieces, shake them in a wooden sieve, shake them into a ping-pong ball, and then dry them. Then the briquettes are ready.
The technique of making briquettes is simple. As long as enough people are sent, they can produce briquettes. Although it is not as efficient as subsequent generations of machine suppression, it is also considered waste utilization. At least, pulverized coal, which accounts for less than half of the coal mine's output, is not used.
In fact, the Huffman coal mine is not particularly troublesome about the problem of pulverized coal. Because the Wiggins Chamber of Commerce needs a limited amount of coal. This has also led to Huffman coal mines not rushing to deal with those pulverized coal.
However, as the amount of coal digging in coal mines is increasing, the amount of pulverized coal piled up by no one is increasing, and it is almost a hill. Therefore, out of the idea of dealing with these obstructing pulverized coals, the old Huffman consulted Marin.
Unexpectedly, Marin really had a way. But in fact, Marin, a better honeycomb technology, has not revealed it. However, Marin found it difficult to make honeycomb. UC Reading www.uukanshu.com
Because the 12 holes of honeycomb coal must be consistent. Otherwise, the holes of the upper and lower honeycomb coals cannot be aligned. In this way, combustion is affected.
Aligning the 12 holes was difficult in this era. Unless, it comes out of a mold. However, in this era there was no machine to press the honeycomb coal, and it could only be pressed one by one manually by using a mold.
For newly manufactured molds, the perforations may not be aligned with the perforations of another mold, and cannot reach a uniform standard. Therefore, Marin, who is troublesome, simply released the briquette technology with high versatility first, which can be considered as a problem for the family.
In fact, briquette technology is really not a technology. If Europeans have been using coal for a long time, it should be easy to think of. However, Europeans have not been using coal for long. Even now, the European steel industry still uses charcoal in large quantities. There are few coal applications and short time, so few people study how to apply coal powder ...
Moreover, after listening to the report from the prospector at the mine, Marin threw money again and bought the 2000 acre hilly area next to Huffman Estate.
According to the prospector, the coal mine at Huffman Manor is actually a branch of the large coal mine underground in the hilly area above.
Marin is a local tyrant now. Since the main vein of the coal mine knows where, can he let it go? So, when the money hits it, the hills are at hand. It's not expensive, only two thousand gold coins, on average one acre requires one gold coin. Because the hills can't plant land, the grass doesn't grow well, and it's not worth it at all. And the officials of the lord, did not know that this hill is buried with large coal mines ... Besides, the Huffman family sells coal and pays taxes ...
