I didn’t expect that the navigability of the Nandu River would be so terrible. Everyone present felt extremely disappointed. How can we use a boat with this water depth?
Just using Ming Dynasty water transport ships to transport coal also requires some regulation of the channel. As for the river-sea combined transport of large ships, it is necessary to carry out comprehensive channel dredging and regulation of the entire downstream. Even now the entire Hainan is in the hands of the Crossing Group, materials and manpower
Opening up supply is a huge project and a huge investment, and I am afraid it will have to have a place in the five-year plan.
"So let's think of a solution based on the boat."
"Install an engine for the traffic boats. The faster the speed, the more traffic boats will be able to run more times... 12 more boats will be able to run once more, which will increase the transport capacity by 60 tons!"
"Install a small steam engine. The steam engine used in this kind of small boat is now easy to manufacture." Jiang Ye said, "And Li Di's small steam engine can be used as a copy object."
Of course, installing a steam engine requires sacrificing part of the payload, but the increase in total transport capacity makes it worth the cost.
"The standard load of a traffic boat is 5 tons. If you install a steam engine, you also have to load burning coal. The load loss is too big - I think it is better to build a tugboat." Wang Luobin said, "The power of the steam engine can be made larger.
, towing a dozen small barges at the back. The old-fashioned small flat-bottomed barges in the British canals are very suitable - the shape and size of this thing are similar to a rectangular open box, the structure is as simple as possible, and the draft is shallow
Very.”
The final result of the discussion was to immediately start replicating small steam engines and building small barges. In addition, we would build an ore dressing plant in Jiazi Coal Mine.
This is Luo Duo's suggestion. Since the current transportation capacity is tight, why not think in the opposite direction.
"Tang Menglong's report to the Industrial Energy Commission clearly stated that the content of lignite only accounts for 40%, and some of it is not suitable for coking. Coal gangue and other low calorific value coal account for the majority of the production capacity. It is better to select it first and then transport it.
Transport out the lignite suitable for coking, and leave the rest in the Jiazi Coal Mine for the time being. Anyway, there is a lot of wasteland in this time and space."
"Actually, coal gangue has many uses. It can at least burn cement..."
"Compared with cement, coking is more important." Luo Duo said, "Besides, after occupying Qiongshan, we can develop and utilize it on the spot. There is no need to bring all the people to Lingao to pollute the environment."
"Why not just make coke in Jiazi Mine? I've seen the Kailuan coke oven in Bopu. It has a simple structure and no technical content."
"Ji Tuisi won't kill you yet." Wang Luobin said, "Wouldn't the coal-coking joint production equipment he worked so hard to get from the 21st century become useless? The power of this thing is the comprehensive utilization of coking. It directly processes the coal produced during coking.
Tar and waste gas are produced to produce various by-products. If you take the coke oven to Jiazi Mine, what else will it do?"
In the past, Kailuan furnaces were mainly used because of the unstable supply of coking coal. Once the combined equipment was ignited and could not be started and stopped, it was never put into formal operation. Now there are stable supply channels, high pollution, and serious waste of Kailuan furnaces.
It became the first batch of backward technologies included in the elimination list by the Planning Commission.
Ma Qianzhu happily approved the Jiazi Coal Mine upgrade plan proposed by the Industrial Energy Commission and allocated the necessary raw materials and various equipment - establishing a stable coal supply system is now a top priority.
Xiao Gui and others, who were in charge of the steam engine imitation work, first "requisitioned" the American-made small steam engine that Li Di had placed in the shipyard workshop. In Li Di's distressed eyes, the small steam engine was dismantled into eight pieces and marked and mapped one by one.
Prepare to do reverse engineering.
"The industrial design of Laomei is really good!" Xiao Gui looked at the parts all over the floor and praised them, "The structure is really ingenious."
"Can it be imitated?" Ran Yao asked.
"We can't do it exactly the same. Its processing technology and materials are beyond our reach. But our requirements are also low. We can enlarge the size of the parts a little, so that they are almost the same."
While Xiao Gui and Zhou Bili started to imitate the steam engine, the Jiazi Coal Mine Concentration Plant started construction at the same time. Lin Baiguang felt heavy pressure. In his original vision, the Jiazi Coal Mine was just like a small coal mine. Several hundred people secretly dug some coal and then took it.
It's just a matter of shipping it to Haijia Pier for loading. I didn't expect this stall to be unexpectedly big.
"If this continues, won't this Jiazi Coal Mine be clearly labeled with the word 'Australian'?" Lin Baiguang complained.
The coal washing plant is located near the yard of Jiazi Wharf. There is sufficient water for washing coal - coal washing is a high-water-consuming industry, requiring 5 tons of water for each ton of coal. Of course, it is also convenient to discharge sewage along the river. Coal washing does not require advanced technology.
, the technical content of the equipment is not high. It is nothing more than a crusher, jig, dewatering screen and other equipment, which is not difficult to manufacture. The main coal washing facility is the chute.
The power of the coal washing plant is a steam engine. The Industrial Energy Commission shipped a second boiler and two 50-horsepower Mozi II steam engines to Jiazi Coal Mine. They were all installed at Jiazi Pier. One drives the water pump and the other drives the coal washing equipment. The boiler is used
The washed coal gangue is used as fuel, and the plant is designed to process 250,000 tons of raw coal per year.
"Since the Jiazi Pier is equipped with a steam engine, we might as well transport a steam crane there. The loading and unloading speed at the terminal will be much faster. Otherwise, the steam from the boiler will be wasted," Ma Qianxu said.
Zhan Wuya said: "We also need to add a complete set of equipment at Haijia Pier. Otherwise, it will be blocked while it is open."
"The problem at Haijia Pier is not big. We can use the local indigenous labor force to implement human wave tactics. Labor force is not valuable anyway." Ma Qianxu thought for a while, "It's not that I don't want to part with a few pieces of equipment. After all, it is the core area of Ming Dynasty rule. Steam engines
It’s so blatant to flip the boiler.”
Soon a steel monster with long iron arms and constantly spitting out white steam was erected on the bank of the Nandu River. The water pumping station on the river used the power of steam engines to extract river water and supply a large amount of water to the entire coal washing plant. Behind it was built a
A three-story high building with long wooden troughs installed on it - this is the coal washing plant. The raw coal is lifted to the coal bunker on the third floor with a winch driven by a steam engine, and then passes through the processes of screening, washing and jigging from the third floor...
…Finally, the clean coal is discharged at the bottom. Coal gangue and low-quality coal are discharged in the chute midway. The black water from coal washing is discharged into the waste tank for sedimentation and then discharged into the Nandu River - a large amount can be recovered in the sedimentation tank.
This kind of coal has a high water content and takes a long time to dry. Wang Luobin took advantage of its high water content to set up a briquette workshop here, using a steam engine to drive a briquette machine to make briquettes.
Although the dark lignite shipped regularly from the Jiazi Coal Mine is relatively small due to the transportation capacity, it has finally solved the instability of coal supply in Guangdong. Ji Tuisi of the Ministry of Chemical Industry can finally use it with confidence. It has not been officially put into operation since it was built.
The complete set of coal coking equipment is operating at full capacity for continuous production.
The formal commissioning of complete sets of coal coking equipment has brought about a leap-forward development to the chemical industry. The simplest change is that the indigenous sulfuric acid workshop has been shut down. The pollution is serious, and the quality of sulfuric acid fluctuates. The indigenous sulfuric acid is industrially manufactured.
Sulfuric acid replaced it. Other by-products such as gasoline, diesel, asphalt, phenol, toluene, crude benzene, various solvent oils, lubricating oils and paraffin also began to be produced one by one. Especially lubricating oil and paraffin, it is a boon to the machinery industry.
——The lubrication performance of coconut oil scraps is limited after all. In addition to its industrial use, paraffin wax also gives the Ministry of Light Industry an opportunity to manufacture a new civilian product - modern candles. Candles made with paraffin wax as the main raw material
, not only is the cost lower than traditional grease candles, but it is also not comparable to old candles in terms of brightness. The treated cotton candle wick can also be gradually burned as the candle burns, and will not form candle flowers, which will affect the burning and emit black light.
Smoke and odor. As for gasoline and diesel, although the production is extremely limited, it also brings some hope to internal combustion engines with gradually depleting fuel reserves-at least some vehicles will not become weird looking like carrying gas bags.
"Now that we have firewood for steelmaking, we are just waiting for rice for cooking." At a five-year plan implementation work meeting in early December, Ji Wusheng from the Ministry of Steel Industry said, "The third phase of the steel plant expansion project will be completed in 1630.
It will unfold in April of this year.”
The second phase of the steel plant was completed in November 1629. The second phase is mainly to improve the smelting facilities of the steel plant, install steel rolling equipment and increase the production capacity of converter steelmaking. The steel plant still uses imported pig iron to make steel.
Mainly, it has not established its own pig iron industry. The third phase of the project will build two new blast furnaces, two open hearth furnaces, and a new iron ore dressing plant. The ore in Tiandu is of high grade and can be directly used to make steel. Steel
The Ministry of Industry plans to sort the ores and use the best-grade ores to make steel directly, while the lower-grade ores will be used to make pig iron.
The blast furnace under design has a volume of 125 cubic meters and can produce 50 tons of pig iron a day and night. In terms of technical level, it has reached the level of the mid-19th century. When two blast furnaces are started at the same time, the annual pig iron output is 350 million tons. This
The numbers dazzled everyone, 35,000 tons of pig iron! You must know that during the Industrial Revolution, Britain's pig iron production in 1720 was only 25,000 tons.
"This is simply a steel mountain and an iron sea!" Wang Luobin was very excited. With such a huge pig iron production capacity, steel is no longer the bottleneck restricting Lingao's industrialization. Railways, iron-hulled ships, and large-scale all-steel frame structures
Factories, reinforced concrete buildings, complete sets of industrial equipment...all are not a problem.
With a massive supply of steel, the industrial production of Chuanchuan Group can get rid of the current small-scale processing plant-like scale and embark on the path of real large-scale industrial production.
