Release that Witch

568. Chapter 568 Drying Tower

    “Ewww.”Silvy looked at the shells for a while, and looked at Roland’s design sketch for a long time before pointing to the **** section. “It seems that this copper tube is not aligned with the top Nail.”

    “What about springs?”Anna asked, “Is it stuck on both sides of the iron plate?”

    “There is a cockroach.”

    “Left or right?”

    Anna asks for the details and then records the questions one by one on the book.

    After collecting the reasons for the failure, it is the next round of shooting – four shots can just use Asia’s playback capabilities, so that the efficiency of the improvement has naturally become unprecedented.

    Unfortunately, the next two rounds of test failed, and Roland had to announce that he would continue the test tomorrow.

    For Asia and Silvy, their work today is all over. After that, you can go back to the castle to enjoy a delicious afternoon tea, or go to the convenience market to see if there are any novelty items. But for Anna and Agatha, the grenade test is just a small part of the busy work. In particular, Anna, in addition to improving the fuze in accordance with the reasons for failure, has to complete the development and assembly of Stream Turbine.

    Roland was going to follow her to the backyard of the Northern Slope to see the progress of the turbine model, and personal guard Sean brought the news of City Hall.

    “Your Majesty, Deputy Minister of Ministry of Construction, Lowes, hopes that you can go to the furniture area and he said that the first dry distillation furnace has been set up.”

……

    As a must-have for the Coking Factory, the planned ten retort towers are located next to the furnace group at the foot of the Northern Slope Mining area.

    Due to the large-scale deforestation of bricks and iron-making, the furnace group has changed from a small plot of less than 1,000 square meters at the beginning to a vast gap that extends along the mountain. If it weren’t for Roland, it would be forbidden for workers to access the woods near the town. It is estimated that there will not be a tree in the north of the border area.

    Nowadays, although there is coal, the easy-to-obtain charcoal is still the main force of iron smelting. As the tree-removing site is farther away from the furnish group, the workers are aiming at the Northern Slope Mountain – there are hundreds of them every day. The logs were cut off and then dropped from the top of the mountain. From a distance, a small piece of “bald spot” appeared in the green mountain peaks.

    Roland naturally does not ask them to protect the environment in this kind of thing, as long as the dust does not affect the town, he does not care if he cuts the Northern Slope Mountain. After all, this prominent small mountain range is just a negligible corner compared to the Impassable Mountains. There are leaves to maintain the basic vegetation, and there is no need to worry about soil erosion.

    The flats that were opened at the foot of the mountain naturally became the most suitable place for the Coking Factory.

    Roland took the Nightingale and personal guard through the noisy furnace area to the front of the first retort. Lowes immediately greeted him and bowed to him. “Your Majesty, I built this double-layer furnace with refractory bricks at your request. According to the drawings, the upper stove should be closed with iron gates, and the middle mezzanine also has iron plates that can be moved freely, but I don’t know who to look for to make these two things. In addition, the copper pipes and chimneys on the side of the small furnace are also completed, except for these metal members. ”

    Roland went into the oven and checked it out – I have to say that as a former Stonemason member and an old friend of Karl van Bate, Lowes really has a lot of experience in masonry. The inner wall of the nearly two-storey dry distillation tower changes evenly. The gap between each brick is basically the same. The brick joints are also layered and interlaced, and there is no straight seam. It is obvious that not only the arrangement ability is extraordinary, but also the construction attitude is very serious. . It is important to know that even if you use the same drawing, the finished products built by different people may be very different.

    “Good job,” he applauded after checking. “I will arrange for the iron gate and the iron plate to be cast. Then you only use it on the fire surface to cover the refractory bricks.” it will be alright.”

    “Your Majesty,” Lowes hesitant said. “Can you tell me how this stove works?”

    “Why, do you want to be a coking worker?”Roland teased.

    “Of course not,” the other party shook his head. “I have never built such a strange furnace before, so the description on the drawings is not clear, I can only rely on guesswork.” If you can know its specific usage and function, not only can you finish it faster when you build the second seat, but I can also improve it if there are some uncertainties. ”

    So that’s it, Roland laughs. “This kind of furnace is mainly used for dry distillation of coal. How should you see how charcoal is burned? This is also very similar, but the scale is bigger. The lower layer is burned, the upper layer is baked, and the filler is coal. ”

    “Boiled coal with coal?”Lowes was surprised.

    “Yes, after the coal has been retorted, it can be converted into coke and burned at a higher temperature. It is a good fuel for steelmaking. In addition, several by-products are produced during the retorting process, and the pipes on the tower wall are used to collect them, not the exhaust chimney. ”

    WellWhy is there still a small stove built on the side of the stove?

    “There should be no air left in the upper layer during retorting, otherwise the coal will burn directly,” Roland points to the hole reserved in the two furnaces. “The calcined limestone in the small furnace will produce a lot of carbon dioxide – you can understand that it cannot burn. gas……”

    “Your Majesty, I know this,” Lowes said. “This part is taught in the evening class.”

    “That’s simple,” Roland said. It seems that the education for all is expanding a little bit under the efforts of Scroll. “Carbon dioxide will enter the upper layer of the furnace through the pipeline and squeeze out all the air so that the coal can achieve the retorting effect. As for limestone, the gray-white stones used to make cement, the Northern Slope Mountain is everywhere. ”

……

    After inspecting the first tower of the dry distillation and returning along the original road, he stayed by the furnace area for a while.

    Looking at the busy scene in front of me, Roland couldn’t help but feel a little excited. A variety of brick stoves stand side by side, at first glance it looks like a neat red forest, with dozens of columns of smoke rising above the forest, gray, white, and black, intertwined with plain workers and The backward appliances together constitute a very contemporary image. More than a dozen Steam engines are rumbling, pulling the conveyor belt to send pieces of wood and charcoal into the blast furnace; the track system is also laid from the mine, and a small mine car runs through the two places. Between the iron ore transfer speed has long been different.

    After the completion of the construction of the steel mill and the forging plant, this place will inevitably become another core place of Neverwinter City – from ore mining to smelting into steel, and then converting the steel into various raw materials and sending it to the processing plant. This gestation gave birth to the power of human Exceptional, and also gave them the courage to overcome everything.
