The chimney, this is the most distinctive thing in this building, and the black smoke is not small, so the babies look very strange, and the stove at home does not have so much black smoke.

Oh, there is also a saying, that is, this burns bituminous coal, which is more flammable, and it burns coal dust, which is mixed with clay and water, otherwise, this smoke is still thick!

"This chimney, why is it so dark, and there are so many cigarettes, the teacher told you, you remember!"

The teacher changed the topic when he heard it, and he was very happy, and finally got rid of the steam engine car, to talk about the steam engine, this teacher also knew that there was black smoke, there was white smoke, black smoke was burning coal, white smoke was steam, white smoke was black smoke burned out, so much so, I was very worried that the babies continued to ask, this saw that she knew, and did not explain much, at this time, she was looking forward to this road to go longer.

"Teacher, why, why!"

As soon as the children heard the story, they became even more anxious, the road was slow, and the teacher was happy and ready to talk.

"Uh-huh, uh-huh, you touch this plank over here, um, touch it like that, or try it here with the back of your hand."

The teacher first put his hand on the wooden frames decorated on the side of the road, and there are some beautiful lattice holes on the wooden frames.

"Hee-hee, it's hot!"

A lot of naughty babies quickly put their hands on them.

There are also maids on the side, the ladies also curiously put their hands on the wooden frame on the other side, sure enough, it is hot, at this time, these maids, the faces of the ladies are different, so strange, but it is not the babies, it is a new discovery, for them, everything is a new discovery.

"yes, it's hot here, do you know why?"

I know, this pass, you must sell it well, and you would rather not finish it than finish it in a hurry, otherwise, you won't be able to show your ability, will you!

"Teacher, why, let the Lun family know?"

Well, this string of fleshy villain is really a good person, no, he picked up the teacher's teasing, and the teacher also got the momentum and opened the shoulder bag on his body.

Well, in fact, these teachers are also a shoulder bag for one person, and there are also some things to use with them, however, their things will be more, the most is some refined toilet paper, refined toilet paper, this is Yang Qiao specially opened a paper mill, for the women in the family, naturally, Mrs. has it, this maid or something is also stained, besides, since you started to do it, it doesn't matter if you have more or less, and Yang Qiao is not relying on this to make money, even if she relies on this to make money, the people in the family still have to use it first, It is not the poor man, for the farmer has no grain to eat, the weaver has no clothes to wear, and the pig farmer has no pork to eat.

So, the women's handbags in this family have also been changed again and again, well, almost several times a year, the ladies have changed, and the maids have also changed.

The teacher first took out a cup from the bag, unscrewed the lid, took a sip of water, and then put the cup into the bag and closed the lid.

Well, the bag used by this teacher is also the same as the babies, it is a new style of bamboo bag, maybe, there will be a new variety of bag next year, but, this, it should be popular for a while, Yang Qiao plans to give the school's children's schoolbags, and also replace it with this, well, this school, is the real school and not the baby's game school.

"Teacher, teacher, say it quickly, hee-hee, and a cup, you can drink water!"

Yes, this baby has to change the subject again.

Moreover, the baby then took her bag and wanted to open it.

"Okay, okay, don't open it, wait until you get to school, open it again, now, you don't have water in your cup, just now, didn't you drink milk on the train, come, I continued, here, why is it hot, because ah, there is a radiator in it, what is a radiator?"

The teacher paused, is this going to dig a hole?

"yes, yes, what is a radiator."

This handsome baby also followed.

"Radiators, also called hot gas sheets, or hot water sheets, what should go in this is gas, that is, the steam, this is what Lang Jun said, oh, that's what your principal said."

"Steam, is it hot, teacher?"

The babies walked with curious eyes, and looked at the teacher, well, with a mother or maid leading, they were not afraid of walking crookedly and falling.

The teacher is so proud, and he can finally live the addiction of being a teacher, so this chest is taller, the waist is straighter, and this story is longer, well, it's longer, not better.

However, this radiator, what does it have to do with the black smoke, this radiator is burned in another steam boiler room, although the pressure is not very high, but, for safety, Yang Qiao also put this boiler far away, it is for the heating of this place alone, well, it is also used for school power generation, perhaps, there will continue to be changes in this area, this home, a generator here, a generator there, this wire money is saved, but this generator, but there are more, as for why there is hot water in it, It's better to say that the steam turns into water, and then, it becomes cold water, and then it will be discharged and used to water the fields or do other purposes, well, there is also a wastewater pool in this house, which is naturally used to treat wastewater and utilize, maybe it is said that the water here is enough, why is there wastewater treatment, besides, this water is not dirty, not this statement, you know, the river, and some pools in the yard or something, all need clean water, and even, cold water that can be drunk directly, so, these wastewater, Yang Qiao still needs to be specially packed and used, and it is disposed of, rather than being directly discharged.

Well, having money is a toss, the Yang family's winter heating has also changed several ways, from the outdoor brazier, to what hot water pool, and now it's time for this radiator, well, what can it evolve into in the end, Yang Qiao himself can't figure it out.

"What about this radiator, it is to burn the boiler, use the hot gas generated by the boiler, that is, steam, go from the inside, steam, you know, everyone lights the stove at home, boils water on it, and has tried the air sprayed by the kettle, it is hot!" 、

The teacher asked, these babies, that is a deep understanding, well, who has not touched the fire when the adults are not paying attention, tried steam, and, at this time, there is an idea, to know that the fire is hot to burn people, you have to try how the fire burns people, but most of them are tried with candle fire, it is safe, will not burn.

"Yes, yes, my mother is really ruthless, I have to let the Lun family touch the fire of the candle, and let the Lun family touch the teapot spout."

Well, this baby is still young, this memory is still clear, it was taught by the mother, the mother is very bad and bad, and no matter how big it is, she just knows that the fire is hot and the hot water is hot.

The new doll game room, naturally, did not use any fire wall or anything, but used this new radiator technology, radiators, naturally, much safer than the fire wall, the fire wall, that is directly burned bricks, especially in such a large room, the burning temperature is low, well, not enough, therefore, Yang Qiao used the way of boiling hot water, however, here is the circulating hot water, which uses a water pump, at the end of the cold water, the water is pumped into the boiler again, so the water is also circulated in the room, Moreover, under the ground, on the wall, there are radiators, and even, the temperature can be controlled, it is this thermometer, and there are several points in the room that are monitored at all times, and if the temperature is not there, a fan will be used to transport it through the pipe.

And the best use of this radiator is that in the summer, some valves are closed and opened, and it is converted into a live cycle type, that is, the inlet water is the inlet water, and the outlet is the outlet, so it becomes the refrigeration of the room, well, the water cooling system, that is, this radiator is a dual-purpose system, advanced enough.

However, the teacher can't explain the refrigeration, and she doesn't even understand these things, why the groundwater is cold and the water on the ground is hot.
