Chapter 531 Earthen Boiler Room, the Wonderful Use of Hot Stones!

"On April 9, the weather in the depression was sunny, the temperature was -4 degrees to 16 degrees, and the clothing index was hoodies"

"Today's weather finally began to show signs of a significant drop, but fortunately, the sunshine is still very sufficient, so there is no need to worry about the intrusion of low temperatures during the day"

"I received feedback in the morning that the night in the mobile cabins is a bit cold, and we must quickly set up the boiler room and heating pipes to ensure that the temperature is maintained at night to prevent large-scale colds!"

"Because of the continuous physical work, the food supplies have been consumed very quickly recently, which has greatly exceeded the previously predicted curve. It is expected that the time for food to run out will be 19 days earlier"

"However, misfortunes often bring blessings. After the rapid consumption of food supplies, the physical fitness of all villagers has improved a lot, even the women who were previously powerless We can now shoulder heavy work!"

"The tree people are still calm as always, but they are not in a hurry. I don't need to rashly make trouble for the time being. Wait until I finish dealing with Liberty City."

"The growth trend of rice leaf seeds is stable, and the sunshine conditions are sufficient. Water 220ml today!"

"Today's survival point harvest is 967, the survival point balance is 2110, the harvest of the receiving point is 4, and the balance is 9!"

"Accumulating survival points is still a long way to go. Let's save the receiving points first. Try to get ten points and upgrade this hot stone mine resource."

"Hey, the sound of the wind today actually brought Lu Yongyi's voice. Wow, they actually found a large island on the sea to settle down. This little life is really comfortable, but time is really fast~~"

"April 10, the low The weather is cloudy, the temperature is -6 to 15 degrees, and the clothing index is sweaters and jackets."

"As expected, the temperature is still maintaining a steady downward trend. According to the amplitude, it will drop to minus ten degrees for the first time in about seven days."

"After urging the construction progress of the boiler room yesterday, we finally completed the general mold in the evening. After we find a way to lay the pipes today, we can start testing the heating."

"The winter wheat on the arable land can also be planted today. If there are no problems, it is expected that the first batch of grain crops will be harvested in the depression in about 60 natural days, and then we will move towards self-sufficiency."

"The wonder has begun to take shape. As long as Ai Jianfeng's iron smelting furnace is ready and produces the first batch of steel, it can be quickly poured to form the skeleton."

"Speaking of this, Hao Qiang's The training speed is not slow either, with various abnormal levels simulated in virtual reality. In two days, although there is still a lot of theoretical knowledge lacking, in terms of practical experience, it can be compared with the undercover agents who have been trained for one or two years. At this speed, I will probably be able to return to Liberty City tomorrow! "

"The growth trend of rice leaf seeds is stable. Water 300ml today"

"670 points of survival points harvested, 2780 points of survival points balance, 4 points of the title harvested, and 3 points of balance!"

"No, the survival points are really getting less and less. If I don't go out to make trouble, sooner or later I will be reduced to one or two hundred points. I have to go out and make a big ticket!"

"Today, the sound of the wind blowing"

"The dwarves deployed in the Blackstone camp have finally withdrawn. The previous repeated jumps, do you really think you can blow me up? "

"However, the conflict between the Bright Empire and the Demon Soul Clan seems to be more serious. I don't know what they are up to. The Demon Soul Clan obviously has a way to eliminate this war in advance, but they have to drag it to this point."

"It's so troublesome. Can't everyone be more obedient at this stage of development? They have to fight each other. If this affects the future business of the exchange, it will be difficult to deal with it!"

Standing on the Fruit Tree Hill, Su Mo wrote the last sentence of the diary, turned off the system daily information, and took the notebook and the pen back into his arms.

The cool breeze mixed with the warm light of the sun blew on his face. It was obviously a hot summer a month ago, but now it has a dry feeling before the arrival of winter.

The leaves of most of the fruit trees on the Fruit Tree Hill have fallen off or become bald under such temperature differences and wind.

The previously desolate land is now covered with neat grass. Covering the ground, it is no longer so abstract.

Some roads opened by humans, against the backdrop of such grass, also look like a razor scratching the scalp, leaving a striking mark.

Putting aside other external conditions, the Hope Village trapped in the center of the depression is like an isolated island in the sea, looking both happy and sad.

As if isolated from the world, the curling smoke rises from the center of the village, which looks quite different.

"Hey, Director, you are here, everyone has been looking for you for a long time!"

Admiring the "ant moving" below, Su Mo turned his head and laughed when he heard the familiar voice of Chen Shen from behind.

"Is this the boiler room and pipeline finally finished?"

Chen Shen nodded: "Finished! I worked overtime yesterday to lay the skeleton, and today I put the materials on, and I am waiting for the director to hang up the sign to start the test run"

"If there is no problem, we can try the first heating tonight!"

"What are you waiting for, let's go! "

When Su Mo heard that the boiler room had been fully installed and could be tested for leaks, he immediately became energetic. His brain, which had been sluggish for two days, suddenly became active again.

The news of the past two days did not completely relieve the mental fatigue of the past few days.

But after stopping, Sumo did have more plans and preparations for the next task.

Today, the boiler room is the top priority.

As long as it can be ensured that the heating can operate stably according to the previous design, the biggest threat will be lost this winter.

Even in the terrifying and extremely cold weather of minus 40 degrees Celsius, with the help of super-powerful heating, Sumo is confident that the damage to the depression will definitely be several orders of magnitude less than other New World territories!

It's even possible

Pass without any injuries!

After walking down the mountain, following the opened road, the two quickly arrived at the back of the village, next to the previous kitchen.

As a well-known member of the energy conversion equipment, the structure of the boiler is not complicated, and the technical barriers to manufacturing are mostly in materials.

Its main working principle is also easy to understand, that is, hot water is heated in the furnace, and the water vapor generated drives the water flow through the laid pipes, over and over again, continuously releasing heat along the way.

As a major country in thermal power generation, China's boilers can be found in almost all first-tier cities and as small as villages with hundreds of people.

In the distance, Sumo couldn't help but get excited when he saw the familiar shape and the mud house built outside but not yet dry.

"Good guy, I missed this thing every winter in the south in the past few years. Now I didn't expect that in the apocalypse, I made it myself."

"This is such a good baby!"

In front of the boiler room, more than 30 responsible workers have occupied the door, busy carrying out various debugging.

Everything is simple, except for the red cloth of "Old Acquaintance" hanging on the wooden sign above, that is, a decent ribbon hanging on the door, symbolizing the ribbon cutting!

"Director, the boiler construction was very successful. I guarantee you with my personality that there will definitely be no problems this time."

"As long as there are no problems in the pressure test, the boiler, which is a non-technical thing, as long as it is properly maintained, will not be a problem for more than ten years!"

Patting his chest, Ai Jianfeng, with a coal-black face, walked up with full pride.

As the saying goes, there are three things a new official needs to do when taking office!

In the past two days, he has been busy enough. Except for necessary sleep and rest, Ai Jianfeng has been working almost continuously the rest of the time.

In order to ensure the smooth progress of each project, he does everything personally including basic shoveling and material selection.

It is no exaggeration to say that excluding the human resources construction part, Ai Jianfeng alone has achieved more than 70% of the efforts in other parts, which is extremely astonishing.

And this is also the reason why he dares to guarantee it.

"Oh? So confident, Jianfeng!"

"Don't worry, Director, we are definitely professional in this aspect of machinery!"

Ai Jianfeng took the scissors from the person next to him and handed them to Su Mo. Ai Jianfeng's face was full of excitement.

Looking at him like this, Somo was speechless.

Amid the neat applause of more than thirty people, Sumo stepped forward, first pulled away the red cloth of the plaque above, revealing the three characters "heating room", then waved his scissors and cut the ribbon into two.

Wow!

After the simple ceremony, more than thirty people entered the boiler room in an orderly manner and began preparations as if they had been well drilled.

Ai Jianfeng also walked to the middle section where the instruments were placed, and began to adjust the air pressure in the boiler to detect possible problems.

After a while, as the pointers on several instruments stabilized and the pressure indicator lights turned green, Ai Jianfeng pressed lightly and the sound of water flow began to sound.

Like the tests before Northern Heating, this step also involves pressurizing the interior, thereby forcing water to rise through the pipes.

Among them, if there is water leakage or no joints, the pressure indicator will fluctuate up and down.

And this is also the first step to discover the problem.

"The cycle progress is 30%, the pressure index is stable, and the water flow speed is stable. Passed!"

"Open the gate at 30%!"

As soon as Ai Jianfeng finished speaking, a loud waiting voice rushed out and shouted to the people on the other side of the village.

With a crash, the baffle stuck at 30% was unscrewed by the people waiting above the pipe, and then the water flowed down again.

"The cycle progress is 70%, the pressure index fluctuates, check whether there is any water leakage problem in the middle section, and report it in time!"

After turning on more than half of the pressure, the air pressure gauge among the three pressure gauges suddenly began to fluctuate to a certain extent.

After nervously shouting to the outside, after thinking for a while, Ai Jianfeng simply dropped his pick and rushed out with his head covered.

"Hey, this index is really strange. It doesn't feel like a water or air leak, but something is pumping out air pressure and disappearing."

Without Ai Jianfeng, everyone naturally turned their attention to Su Mo.

Not having any stage fright, relying on his own experience of playing in the boiler room when he was a child, Sumo stepped forward carelessly and began to make judgments.

"The speed of the water flow is stable and there is no problem. The only way to affect the air pressure is"

"The temperature inside is constantly dropping, causing pressure fluctuations?"

Guessing a possibility, Sumo immediately opened the system panel and issued an appraisal directly to the boiler room.

Different from the faint green light before, for this "big guy" in the territory, the light identified by the system is finally much darker, with some yellow spots.

As the light puffed out, the attribute panel of the boiler room slowly lit up.

[An earthen boiler room with rough workmanship (ordinary -: minor flaws)]

[Description]: The boiler room made using rammed earth technology can maintain the heating demand with a pipe length of less than 500 meters. In terms of withstanding pressure, the natural uncertainty brought by rammed earth can only be said to be so-so. Once burned, Excessive pressure may cause a risk of explosion.

However, taking into account the complete prevention and control measures and the standard monitoring code list, the probability of such risks will be reduced to a certain extent.

The current quality has declined due to the presence of a hot stone at 26 meters of the pipe, which absorbs and releases heat. Removing this hot stone will return the overall quality of the boiler room to normal.

Replacing all pipes with hot stone materials can greatly improve the quality of the boiler room and produce special effects.

[Boiler separation]: Domestic boiler

[Fuel type]: diesel, kerosene, heavy oil, coal, wood hot stone (reusable), natural gas, liquefied gas, biogas

[Boiler pressure]: normal pressure (one standard atmospheric pressure)

[Special ability]: Locked (can be unlocked by improving quality to excellent level)

[Heating intensity]: Current pipeline length: 341 meters, temperature: 1 degree (full load: 36 degrees, economical: 24 degrees, insulation: 20 degrees)

[Evaluation]: If you can keep upgrading him, maybe you can get an alchemy furnace?

It is extremely rare that for the first time, the system gives an evaluation that the quality of the item is lower than ordinary.

Of course, this does not mean that there is any congenital workmanship defect in the construction of the boiler room, but that some ghost secretly integrated a hot stone into the pipe.

When it is not saturated, the hot stone will continue to absorb the heat of the water and reduce the air pressure inside the pipe, causing the barometer to continuously swing from side to side.

After absorbing enough heat, it will generate heat again, and on the basis of the previous one, it will produce a pressurizing effect.

"Sure enough, it is this small piece. I searched for a long time before I found one. I didn't expect that someone wasted their resources and integrated this piece into the pipe."

"If I hadn't tested the properties of the hot stones and had the system as an aid, I'm afraid I would have to dismantle the pipes again and check them carefully in this situation."

Without going out to see, Su Mo could guess that Ai Jianfeng was confused and couldn't figure out the reason.

This hot stone has been completely integrated into the iron pipe. Even if you know the location and want to remove it, there is no other way but to replace the pipe.

However, looking at the survival point that had just exceeded 3,000 points in the lower right corner of the system interface, Sumo felt a slight pain. He still stared at it and opened the attached page of the identification panel.

[Upgrade method one]: Iron boiler: All the rammed earth of the boiler is fully upgraded to iron, which slightly enhances the pressure resistance of the boiler so that more steam can be transported to distant places through longer pipes. At the same time, The all-iron boiler material will have a small loss of rigidity. When facing extreme weather, it may increase the risk due to thermal expansion and contraction. Upgrading requires survival points: 2990 (corresponding upgrade materials (iron blocks) can be invested) Reduction, the maximum reduction range is 2650)

[Upgrade method two]: High-efficiency boiler: Upgrade the rammed earth material of the boiler to a more advanced heat-resistant clay, which greatly increases the boiler's heat storage capacity, moderately increases the boiler's pressure resistance, and slightly increases the boiler's risk resistance. ability; at the same time, upgrade the material of the iron pipe and add a high-strength insulation coating to it to prevent steam and water flow from losing heat during the circulation process. The upgrade requires survival points: 4580 (the corresponding upgrade materials (heat-resistant clay) can be invested; Iron blocks; copper blocks; high-quality water sources) are reduced, with a maximum reduction of 3190)

[Upgrade method three]: Alchemy furnace: The upgrade effect is unknown, the upgrade risks are unknown, the upgrade intensity is unknown, and the upgrade requires survival points: 62350 (corresponding upgrade materials (hot stones) can be invested to reduce, the maximum reduction is 60000)
