The total length of existing pipelines in the central cooling tower is 180 kilometers, the diameter of the pipeline is 1.05 meters, and the minimum value of all water flow is 156,000 tons, which does not include the dispatching function of the cooling tower itself.
A total of 170,000 tons of water is required to start the device.
Heat sources include the steelmaking department of Xincheng Heavy Industry, Phoenix Iron Works, automobile plants, locomotive chiefs, the casting department of Blue Sky Heavy Industry, and high-heat private enterprises such as machinery plants.
Taken together, it is not easy to keep 170,000 tons of water warm, and more pipelines will need to be laid in the future.
For example, Firefly City is an area that needs low temperatures. If the temperature of the entire Firefly City is 20 degrees lower than the surrounding area, a large amount of caloric value can be exchanged through natural heat. But to achieve this, at least an increase in heat value must be achieved. Thirty kilometers of pipeline length are only thick pipes, not counting diversion pipes. The overall project may be larger than laying a complete tap water system.
...There is currently no complete water supply system in the territory, which is supplemented by purified water from the sacred tree plus sewer pipes and a small tap water network.
In preparation for the first trial start-up of the central cooling tower, water is supplied from the iron factory and Xincheng Heavy Industry. The hot water produced by the two factories is directly filtered and passed into the return pipe.
The source of water for both factories is groundwater. Pumping too much in a short period of time may cause the foundation to sink, so the actual amount is relatively limited.
The main water body is the water accumulated in the Central Tower Reservoir area due to rainfall after the previous steam explosions. The water is relatively shallow and has not even completely submerged the trees in the valley. There are many impurities, but there is no other way. The only way is to filter it with a filter. A mage was assigned to watch from the side.
In addition, the central cooling tower also has staff who will clean impurities from the reservoir in the tower.
Make sure there is enough water in the reservoir and the overall temperature reaches 30 degrees, and start other preparations.
Thousands of people were mobilized a few days before the start to prepare a pile of firewood under the pipe in the Ice Forest, and lit it during the test to ensure that the pipe wall could provide a certain amount of initial heat, otherwise the water at the front end would inevitably freeze and cause damage to the pipe.
Yes, the pipes in the Ice Forest are all overhead, and this is because the Ice Forest has existed for so long. Using air cooling can also find ways to ensure that the water at the front does not freeze, and it will never flow underground.
Finally, to ensure that the water will not freeze in the Ice Forest, a thermal insulation workshop is prepared inside the Ice Forest near South Town, which is mainly driven by magic.
The heat created by magic is a bit abstract. It is difficult to use magic hours and kilowatt hours to convert heat. It can only be used as an assistant. Try to ensure that the water temperature is higher than ten degrees when passing through the workshop.
After everything is ready and each pressurizing station confirms that the equipment is normal, the cooling tower cycle test is started.
The plane travels faster than the water in the pipe. After the cooling tower is started, the plane flies above the ice forest to light up the signal, and the people on the ground light the firewood pile.
In such a long pipe, the initial water temperature is completely useless. By the time we reach the station pressure station outside the ice forest, the temperature has dropped to 22 degrees.
Fortunately, the fire points were relatively dense, and the water body was able to pass through the magic warming station at a temperature of 25 degrees for a round of forced warming.
When we exit the ice forest, the water temperature at the front is 8 degrees, and the average water temperature is still 19 degrees.
This wave of water returns to the central cooling tower, without passing through the super heat exchanger, and is sent directly to the new city to continue circulation.
The warming effect here in the Ice Forest is still not enough, so we have no choice but to activate a backup plan to heat the return pipe in the north area of Xincheng with coal to ensure that the water temperature returning to the cooling tower exceeds 80 degrees.
Because the pipeline was too long and the temperature of the passing environment was not synchronized, the test lasted for three days before the water flowing out of the ice forest achieved normal temperature output.
Then we gradually reduced the coal-fired auxiliary power in the Xincheng North heating area, during which thousands of phone calls were made.
When coal burning in Xinchengbei completely stops, the Phoenix Iron Works' full production capacity will gradually return to normal.
Finally, after a week of operation, the water temperature at the output end of the Ice Forest stabilized between 8 and 12 degrees.
The overall heat is still slightly insufficient, and the production load of Phoenix Iron Works is still maintained at more than 80%. Under the current conditions, so much iron cannot be sold at all, so we can only continue to build pipelines for the second phase of the central cooling tower project. Preparation, and the magic heating station did not stop during the entire period.
Of course, the purpose of accelerating the completion of the first phase of the project is to cool down the small half of the dark floor and avoid steam damage. From the perspective of heat absorption, the test was successful.
But it can't be used normally.
So when the results were reported to Wang Qi, he decided to stop and build some distribution pipelines first, especially to make full use of the heat from Yinghuo City, Xincheng Heavy Industry, and Phoenix Iron Works.
A book-chasing app recommended to me by an old book friend I have known for ten years! It’s so easy to use. I rely on it to pass the time while driving or before going to bed by reading and listening to books. You can download it here..]
Now that the overall pipeline of the central cooling tower has been confirmed to be available, the second phase of the project does not need to be so urgent. The number of engineering personnel will be halved, the slime mold army will be transferred away, and the production capacity of the automobile factory can be restored to normal.
The people who were pulled out still have other projects to do, such as the expansion of evacuation sites in various places, the construction of gas storages, liquid storages, and material storage warehouses.
The slime mold army and the 23rd Regiment Engineering Battalion continued to work on the ring plate defense system.
The original pipeline network of the second phase of the project needs to be adjusted in terms of layout and construction sequence.
The top priority is to lay heat dissipation pipes in the smelting areas of heavy industries and iron plants.
The working environment in the smelting area is very harsh. Controlling the temperature through low-temperature water inflow can not only improve the working environment, but also collect a lot of dispersed heat. Although this heat is not as good as the water used to cool the steel, it is not small, mainly because it is relatively concentrated. , the workload of pipe network layout is small and can be completed quickly.
The manpower that the two factories can occupy is limited, so everyone else goes to Firefly City. The field workers are responsible for the main lines, and the slime molders are responsible for the construction of distributed pipelines and pressure stations in the city.
After Firefly City, there is the central reservoir area. Because the semi-adult ice trees that were planted nearby were transplanted to Black Mountain, additional cold water pipes are now needed to assist in condensation and capture some ambient heat.
The fourth priority for the time being is the expansion of the cooling pipes in the Ice Forest.
The existing part of the Ice Forest is just a turn inside, passing through Nanzhen and then back to Phoenix City. The heat absorption effect that can be utilized is very limited. If there is time, at least hundreds of kilometers of pipelines will be laid in it.
Whether it is the fourth one depends on the development of floating islands. If the threat of steam is high, you have to jump in line, but the premise is that the ice forest can withstand the steam and have a certain negative entropy surplus.
After making arrangements for the second phase of the central cooling tower, the Dark Floor block took off on its own.
The randomness is really a bit strong... Of course, it may not be random. It's just that the geological exploration ability is too poor to get the information about the underground boiling water.
That's right, boiling water.
After the plate broke free, the gap became larger and enough light was cast in. At this time, when you go to the break of the red stone plate, you can directly see the sea of clouds below.
The height of the groundwater must have dropped significantly due to the takeoff of the plate. A rough calculation shows that the height of the sea of clouds is three kilometers. Such an abnormal "fog" cannot be caused by natural evaporation. It is basically confirmed that everything below is filled with boiling water.
Just because the contact surface and heat dissipation surface are large, and the height difference is also large, the steam does not affect the upper part of the ground, which is a blessing among misfortunes.
There is also good news. The grassland swamp plate in the west has risen to a height of 2,000 meters. Although it is probably still not out of the vapor hazard height, it is at least a few hundred meters higher than before, and the hazard level has also dropped.
