Different from the previous faint green light, 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 craftsmanship (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. However, 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 the risk of furnace 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 63.26 meters in the pipe, which absorbs and releases heat. If this hot stone is removed, the overall quality of the boiler room will return 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: 14.1 degrees (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 the system gives an evaluation that the quality of the item is lower than ordinary for the first time.

Of course, this does not mean that there was 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 left and right.

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's 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 inspect them carefully when faced with this situation."

Without going out to see, Su Mo could guess that Ai Jianfeng looked 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 in his heart. He still focused his eyes 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, allowing more steam to 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, the risk may increase 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 block; copper block; high-quality water source) to be reduced, the maximum reduction range is 3190)
