The plan written by Xia Yanqing during this period was constructed by her trying to recall the pitiful memories of the development of glass in her previous life, plus some principles that engineering students learned in school.

“…… Liquidity, liquidity, do you understand? All liquid states, such as water, oil, molten iron and molten glass, are fluid. Using this fluidity, the molten high-temperature glass melt in the melting pool is discharged in a flowing manner. At the same time, homogenization and exhaust are carried out during the flow to the cooling pool......"

While explaining, Xia Yanqing divided the pool she had simply drawn into a melting pool, a clarification pool, a cooling pool and a discharge pool.

At this time, the Guan family was already very excited to hear it, but they didn't expect that a difficult matter that had no clue at all was simply solved in the hands of the Xia family woman.

is worthy of being a person who does great things, and his brain is much more flexible than ordinary people!

Qu Jiang and the other three also nodded again and again.

However, Xia Yanqing finished explaining the main structure of the pool kiln, but his tone changed: "If the pool kiln technology is so simple, I think we can develop the continuous feeding technology, and other glass companies can also do it." ”

The Guan family was stunned in an instant, is this really the case? Thinking back to what Xia Yanqing said, they can be understood by laymen, and those who are immersed in glass making, as long as they figure out the joint of using the continuous pool kiln, the next thing is to get all the way.

Qu Jiang's eyes also flashed, they didn't think that they could turn the crucible kiln into a pool kiln. As soon as someone thinks of this step, or if someone in the Technology Development Department occasionally leaks the shape of the kiln, someone who specializes in glass manufacturing can immediately figure out the next step.

Xia Yanqing saw that they were all listening carefully, and they had no intention of selling Guanzi, and then said: "The big processes are all stuck in the imagination, once the idea is reached, these processes don't have much technical content after that. So, what we want is the details. ”

Xia Yanqing wrote the word "detail" in the corner of the wooden board with a thick charcoal strip.

"For example, in the melting part of the kiln, for example, in order to better absorb heat and prevent heat loss, we can build this part of the kiln in the furnace and make it a semi-open ......."

Xia Yanqing said, adding another part of the melting pool with carbon strips, and simply marked it as a brick.

Then let's talk about it further: among them, the heating method of the kiln can be divided into multiple heat points in order to provide uniform heating. There are also insulation bricks, insulation methods, heat storage chambers, etc., a series of them, all of which have been talked about.

Below, Qu Jiang and other three insiders, the more they listen, the brighter their eyes become. The word "details" is really not highlighted, it is really important.

If you continue along this line, three or even three and a half sides of the melting pool will be the heating surface. This idea still saves fuel usage and the melting time of solid raw materials will be greatly accelerated. All of these are effective measures to reduce the production cost of glass and increase output.

The Guan family listened sluggishly, and they couldn't understand many things in it. But just looking at the generals and a few other insiders who are so excited as if they have picked up a treasure, thinking about what the woman of the Xia family said, it must be very insightful and very important.

Guan Xiao and Guan Tong didn't know when, they had already brought pen and paper, and they were listening and memorizing. Although they couldn't understand what Xia Yanqing said for the time being, they could write it down and figure it out slowly. Moreover, in the process of developing the craftsmen who will be supervised in the future, they will also be able to comprehend what they hear today and compare it with the development site.

“…… There is also a clarifier, in order to better homogenize the molten glass and allow the gas in the molten glass to fully overflow, we can artificially increase the flow distance of the molten glass......"

Finally, Xia Yanqing talked about another important point that everyone has overlooked: "Our development not only needs glass craftsmen, but also smelting professionals, blast professionals, and craftsmen who build fire wall flues. Everyone brainstorms together to get things done. ”

has been talking for more than an hour, and Xia Yanqing has smoothed down the general development direction of the pool kiln technology that she can think of. As for how far it can be carried out in the future, it depends on the skill level of the craftsman who will be the supervisor, and there is very little help she can provide here.

Waste heat utilization is an energy technology that all enterprises have to involve in the era when she grew up.

"Smoke, flue professional?" Qu Jiang and the others were listening attentively, and suddenly heard the fire wall or something, thinking that there was something wrong with their ears.

I'm discussing high-end technical issues, why did I suddenly get involved in such a down-to-earth thing as the fire kang?

Xia Yanqing mentioned employing people, smelting majors, blower majors, glass craftsmen, Qu Jiang can understand, but what is the situation of fire walls, fire kangs and flues? Is it good that the wind horse and the cow are not related?

Xia Yanqing saw that Qu Jiang did not understand, so he drew the entire side of the pond kiln on the wooden board, marked the direction of the flue, and also drew a mezzanine on the side of the excessively long flue, explaining: "The flue gas after fuel combustion also has enough heat. This heat may not reach the temperature at which the glass will melt, but it can preheat the raw glass and the air flow sent in by the bellows. In particular, the air flow fed in by the blast air is preheated, which will definitely save fuel and speed up the melting time of the glass raw materials. ”

Qu Jiang was pondering, and the official he brought was already stunned, full of question marks: "The smoke after the fire...... Aren't they all drained? Is this bit of heat worth recovering? ”

Before he finished speaking, he was glared at fiercely by Qu Jiang, "Didn't Miss Xia mention the fire wall and the fire kang just now?" What have you been listening to? There are so many palaces in the imperial palace, and they can be as warm as spring in winter, so isn't the heat source all the smoke after the fire? ”

The dignified general is a four-grade official, holding the imperial court's Yulu, and his subordinates are in charge of hundreds of top craftsmen, but he said such uninformed words, which is simply a shame for him as a big eunuch.

"Forehead......" The official blinked, embarrassed. How did he forget about this stubble? On weekdays, whether it is smelting or building weapons, the smoke is emitted with the flames. It's not that the smoke doesn't have heat, it's that the heat is nowhere to go.

Wrong...... The official instantly woke up, probably not useless, but they just didn't expect it.

According to Miss Xia's meaning, a lot of blast air is needed in the smelting furnace, which is all cold wind, especially in winter, when a lot of wood is used.

If you pour the air conditioning into the smelting furnace and preheat it with flue gas, can you save a lot of wood?

The official's face was full of yearning, if he could make improvements in smelting technology, would he be able to make a name for himself in the craftsman world!

Guan Benhe and others have already listened to stupidity, and they have also looked stupid.

This Xia girl is really talented, look at this Master Qu, that is going to be the eunuch, and the two he brought are not idle people. But in the face of a girl who is less than twenty years old, why does she seem to be ignorant everywhere?

Qu Jiang didn't care about what the Guan family and the others thought, he nodded heavily, and said, "In this way, it is indeed necessary to have craftsmen who are proficient in wind blowing to design the two flues. Miss Xia rest assured that these professional craftsmen will be overseers. If there is still a shortage, the official is responsible for finding someone from the Ministry of Works, and he must not delay the matter. ”
