Daming Town Haiwang

Chapter 54, Honeycomb
"With coal?"

As soon as Liu Jin's words fell, Emperor Hongzhi, Liu Jian, Xie Qian, and Li Dongyang were all slightly dumbfounded. They thought that Liu Jin could come up with some good solution, but they didn't expect Liu Jin to come up with such an idea.

"After all, he is still too young. Doesn't he know that the smoke from this coal is poisonous?"

Emperor Hongzhi looked at Liu Jin and couldn't help shaking his head slightly.

"What he said about the Golden Continent must not be a random fabrication. He didn't even know about the poisonous gas produced by burning coal. It's really hard to believe his words."

Liu Jian frowned slightly, and looked at each other with Xie Qian and Li Dongyang, and they both saw suspicion in each other's eyes.

"My lord, this coal is indeed very cheap, and a load of coal only costs a few tens of pennies, but does your lord know why everyone uses charcoal instead of coal?"

The waiter at the side couldn't help it anymore, the young man in front of him really met the standards of a scholar, he only read the books of sages and sages, he didn't hear anything outside the window, and he didn't even know about the poisonous gas produced by coal.

"Of course I know that burning coal will produce poisonous gas, which is easy to kill people. In addition, coal should not be ignited, and it is extremely inconvenient to use. Compared with charcoal, it is much more convenient and will not produce poisonous gas."

Liu Jin looked at the crowd, smiled and said confidently.

"Young master is right. Since you know that using this coal will kill people, why do you want everyone to use coal? Isn't this clearly telling everyone to die?"

The waiter in the shop was slightly taken aback, he didn't expect Liu Jin to know so clearly.

"Although coal produces poisonous gas when it burns, this poisonous gas is easy to kill, it is not easy to ignite, and it is inconvenient to use, but this coal burns for a long time and has high heat. It is very good whether it is used for heating, cooking, boiling water, etc. , and more importantly, the price of this coal is very cheap, a load of coal is only a few tens of pennies, and everyone can afford it."

"We have an old saying that seeks the advantages and avoids the disadvantages, and there is also an old saying that takes the essence and discards the dross. This coal has many advantages. As long as we can solve the poisonous gas produced when coal is burned, it can be used with confidence."

Liu Jin replied with a smile.

"But the burning of coal will produce poisonous gas, how to solve this?"

When Xie Qian heard this, he asked quickly, and everyone else stared at Liu Jin one by one. If Liu Jin can really solve the problem of poisonous gas produced when coal is burned, it will be very beneficial to the country and the people.

"To solve the poisonous gas produced when coal is burned, we must first understand why the coal produces poisonous gas when it is burned, and why the charcoal does not produce poisonous gas."

Liu Jin looked at Xie Qian, then came to the place where charcoal was piled up, picked up a piece of charcoal and said: "This coal and charcoal are both black, and they can be burned for heating, which means that they are the same in essence. It's all made of something that burns to keep warm."

"However, the burning of charcoal will not produce toxic gas, and the burning of coal will produce toxic gas. This shows that there must be something else in the coal. It is this kind of thing that produces poisonous gas when it is burned. Once inhaled this poisonous gas, it is easy to be poisoned and die."

Liu Jin analyzed slowly, and the others nodded slightly when they heard Liu Jin's words. After thinking about it carefully, it seemed that what Liu Jin said made sense.

"You mean to say that we only need to remove the poisonous stuff in coal to be able to safely use coal."

Li Dongyang rolled his eyes, thought for a while and said.

"That's right, we just need to remove the toxic stuff in the coal, and we can safely use coal for heating and fire without worrying about poisoning at all."

Liu Jin nodded solemnly and said: "The poisonous substance contained in this coal is sulfur. After sulfur is burned, sulfur dioxide will be produced. This sulfur dioxide is a poisonous gas. Excessive inhalation can easily lead to poisoning and death."

"I know sulfur, but I don't understand sulfur dioxide."

Hearing Liu Jin's words, Liu Jian asked quickly.

"You can understand this sulfur dioxide in this way. It is a new thing formed after sulfur is burned, just like the charcoal will form ash after burning. After the coal burns out, it will also turn into ash and produce poisonous gas. Sulfur dioxide."

Liu Jin rubbed his head. People in this era don't even know about chemistry, and they don't even have the most basic understanding of the natural sciences. There is no way to talk to them about sulfur dioxide and the like. It's enough to simply let them know what it means.

"That's it~"

Sure enough, with Liu Jin's explanation, everyone else nodded to express their understanding.

"Then how to remove the sulfur in the coal?"

Emperor Hongzhi was already a little excited at this time. It seemed that Liu Jin could really solve the problem of sulfur in coal, so that everyone could use coal.

If it is really possible to replace charcoal with coal, the coal of tens of pennies a load will be much, much cheaper than the coal of hundreds of pennies a load, and ordinary people can afford it. The number of people who freeze to death will be greatly reduced.

"This is a bit complicated. To put it simply, the sulfur in the coal is washed out by washing, and then the coal and yellow mud are mixed in a certain proportion to make honeycomb coal, so that it can be used safely. .”

Liu Jin touched his head in embarrassment. This is another chemical issue. The coal used in later generations basically has to go through the process of coal washing, using some chemical reactions to remove the sulfur in the coal. .

Then it is made into honeycomb coal, and it is convenient and affordable to use a coal stove to burn honeycomb coal. It has been the main choice for household fires for a long time.

However, in the 21st century, environmental protection is emphasized, and the use of gas and electricity is gradually advocated, so fewer and fewer people use honeycomb coal, especially in cities, honeycomb coal has basically been eliminated, and only some small cities and Still in use in rural areas.

"wash?"

"coal washing?"

"Honeycomb?"

When everyone heard this, they all felt a little dumbfounded. They had never heard of such a thing before. The coal was used for burning, and they wished that it was drier so that it would be more convenient to use and burn.

Now it is going to be washed, and it is said that the yellow mud will be put into it to make some kind of briquette. This is really unbelievable and unheard of.

"Master, if you want to buy charcoal, we welcome you, but if you want to smash the signboard of our shop, although our shop is small, it is not for bullying."

When the shop waiter heard this, he said to Liu Jin directly and bluntly, he could see that the person in front of him was here to find fault.

　It seems that no one uses coal now, right?
