Chapter 507 Coal Washery

Unexpectedly, the navigability of Nandu River is so appalling.Everyone present was disappointed.What kind of boat is there to play in this depth of water?

It's just that the waterway needs to be reorganized to transport coal with the water transport ships of the Ming Dynasty.As for large-scale river-sea combined transport, it is even more necessary to carry out comprehensive dredging and improvement of the entire downstream channel.Even if the whole of Hainan is now in the hands of the Crossing Group, and the supply of materials and manpower is open, the large amount of the project and the huge investment may still have a place in the five-year plan.

"So let's find a way based on the boat."

"Install the engine on the traffic boat, the speed is faster, the traffic boat can run more times - 12 more runs will increase the transport capacity by 60 tons!"

"Installing a small steam engine, the steam engine used in this kind of boat is not difficult to manufacture now." Jiang Ye said, "And we can use Li Di's small steam engine as an imitation object."

Installing a steam engine will naturally sacrifice part of the payload, but it is worth the price to be able to run a few more times and increase the total transport capacity.

"The standard load of a traffic boat is 5 tons. If you install a steam engine, you have to load the burning coal. The load loss is too great-I think it's better to build a tugboat." Wang Luobin said, "The power of the steam engine can be made larger. , and tow a dozen or so small barges behind it. 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, as simple as the structure is, and the draft is shallow. Very much."

The result of the final discussion was to immediately start imitating small steam engines and building small barges.In addition, set up a concentrator in Jiazi Coal Mine.

This is Luo Duo's proposal.Since the capacity is tight now, why not have a reverse thinking.

"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 and then transport. Transport out the lignite suitable for coking, and leave the rest at the Jiazi Coal Mine for the time being, anyway, there are wastelands in this time and space.”

"In fact, coal gangue has many uses, at least it can burn cement..."

"Compared to cement, coking is more important." Luo Duo said, "Besides, after occupying Qiongshan, it can be developed and utilized on the spot. There is no need to drag all the brains to Lingao to pollute the environment."

"Why don't you just make coke in Jiazi Mine? I've seen the Kailuan-style coke oven at Bopu. It's very simple in structure and doesn't have much technical content."

"Ji Tuisi won't kill you." Wang Luobin said, "The coal coking joint production equipment he worked so hard to get in the 21st century will be scrapped? The power of this thing is the comprehensive utilization of coking. It directly processes the coking produced during coking. Tar and waste gas, all kinds of by-products are produced. You took the coke oven to Jiazi Mine, what else would he do?"

In the past, the Kailuan furnace was mainly used because of the unstable supply of coking coal, and once the combined equipment could not be turned on and off once it was ignited and started, it has not been put into formal operation.Now that there is a stable supply channel, the highly polluting and wasteful Kailuan furnace has become the first batch of outdated technologies included in the elimination list by the Planning Commission.

Ma Qianju happily approved the Jiazi Coal Mine upgrade plan proposed by the Industrial and Energy Commission, and allocated the necessary raw materials and various equipment-establishing a stable coal supply system is now a top priority.

Xiao Gui, who presided over the steam engine imitation work, first "requisitioned" Li Di's American-made small steam engine in the workshop of the shipyard.Under Li Di's distressed eyes, this small steam engine was dismantled into pieces, marked and mapped one by one, ready for reverse engineering.

"Lao Mei's industrial design is really good!" Xiao Gui looked at the parts all over the floor and was full of praise, "The structure is so ingenious."

"Can it be imitated?" Ran Yao asked.

"It's impossible to do exactly the same. Its processing technology and materials are beyond our reach. However, our requirements are also low. We can enlarge the size of the parts, so that it is almost the same."

While Xiao Gui and Zhou Billy started to imitate the steam engine, the Jiazi Coal Mine Concentrator started construction.Lin Baiguang felt heavy pressure. In his original vision, the Jiazi Coal Mine was just a small coal mine.Hundreds of people secretly dug some coal, and then shipped it to Haijia Wharf for loading.Unexpectedly, the stall was unexpectedly large.

"If things go on like this, won't the Jiazi Coal Mine be clearly labeled with the word 'Australian'?" Lin Baiguang complained.

The coal washing plant is located near the storage yard of Jiazi Wharf.There is plenty of water here for coal washing—a water-intensive industry that consumes 5 tons of water per ton of coal.Of course, it is also very convenient to discharge sewage by the river.There is no advanced technology in coal washing, and the technical content of the equipment is not high.It is nothing more than equipment such as crushers, jigs, and dewatering screens, and it is not difficult to manufacture.The main coal washing facility is the chute.

The coal washing plant is powered by a steam engine, and the Industrial Energy Commission transported a second boiler and two 50-horsepower Mozi II steam engines to Jiazi Coal Mine.All installed at Jiazi Wharf.One drives the water pump and the other drives the coal washing equipment.The boiler uses the washed coal gangue as fuel, and the factory is designed to process 25 tons of raw coal per year.

"Since Jiazi Wharf is equipped with a steam engine, a steam crane can be transported to the wharf, and the loading and unloading speed at the wharf can be much faster. Otherwise, the steam from the boiler will be wasted." Ma Qianzhu said.

Zhan Wuya said: "It is necessary to add a whole set of equipment at Haijia Wharf. Otherwise, traffic will be blocked at the same time."

"The problem at Haijia Wharf is not a big problem. We can use the local indigenous labor force to engage in crowd tactics. Labor is worthless anyway." Ma Qianzhu 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 The boiler is too blatant to fiddle with."

Soon a steel monster with iron arms and white steam was erected on the banks of the Nandu River. The pumping station by the river used the power of a steam engine to pump the river water to supply a large amount of water to the entire coal washing plant.Behind it rose a three-story building with long wooden troughs—this was the coal washing plant.Raw coal is lifted to the coal bunker on the third floor by a winch driven by a steam engine, and then passes through a process of screening, washing, and jigging from the third floor... Finally, clean coal is discharged at the bottom.Coal gangue and low-quality coal are discharged in the chute on the way.The black water from coal washing is discharged into the waste water tank for sedimentation and then discharged into the Nandu River - a large amount of fine coal can be recovered in the sedimentation tank.This fine 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 regularly shipped from Jiazi Coal Mine is limited in capacity and arrival is relatively small, it has finally solved the instability of coal supply in Guangdong.Ji Tuisi of the Ministry of Chemical Industry can finally safely use the complete set of coal coking equipment that has not been in official operation since it was built, and start continuous production at full capacity.

The official commissioning of the complete set of coal coking equipment has brought leaps and bounds to the development of the chemical industry.The simplest change is that the indigenous sulfuric acid workshop was shut down, the pollution was serious, and the quality of the sulfuric acid fluctuated up and down. The indigenous sulfuric acid was replaced by industrially produced sulfuric acid.Other by-products such as gasoline, diesel oil, asphalt, phenol, toluene, crude benzene, various solvent oils, lubricating oil and paraffin are also produced one by one.Lubricating oil and paraffin, in particular, are simply good news for the machinery industry-after all, the lubricating properties of coconut oil scraps are limited.In addition to industrial use, paraffin wax also gave the Ministry of Light Industry an opportunity to manufacture a new civilian product-modern candles.Candles made of paraffin wax as the main raw material are not only lower in cost than traditional grease candles, but also not comparable to old-style candles in brightness. The treated cotton yarn candle wick can also be burned gradually with the candle burning, and will not Candle blossoms affect the combustion and emit black smoke and odor.As for gasoline and diesel, although the output is extremely limited, it also brings some hope to the internal combustion engine whose fuel reserves are gradually depleted-at least some vehicles will not be reduced to the strange appearance of wearing gas bags.

"Now that we have the firewood for steelmaking, we have to wait for the rice for cooking." At a five-year plan implementation work meeting in early December, Ji Wusheng of the Ministry of Iron and Steel Industry said, "The third phase of the expansion of the iron and steel plant will be completed in 12. Launched in April of the year."

The second phase of the steelworks was completed in November 1629.The second phase is mainly to improve the smelting facilities of the iron and steel plant, install steel rolling equipment and increase the production capacity of converter steelmaking.The production of iron and steel factories still mainly uses imported pig iron to make steel, and they have not established their 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 beneficiation plant.Tiandu's ore is of high grade and can be directly used for steelmaking.The Ministry of Iron and Steel Industry plans to use the ore with the best grade to make steel directly after the ore is sorted, and use the lower grade ore to make pig iron.

The volume of the blast furnace under design is 125 cubic meters, and it can produce 50 tons of pig iron a day and night, which has reached the level of the mid-19th century in terms of technical level.The two blast furnaces started working at the same time, and the annual pig iron production is at the level of 35000 million tons. This figure makes everyone feel bright, 35000 tons of pig iron!We must know that during the industrial revolution, Britain's pig iron production in 1720 was only 25000 tons.

"This is simply a mountain of steel and a sea of ​​iron!" Wang Luobin was very excited.With such a huge pig iron production capacity, steel is no longer the bottleneck restricting the industrialization of Lingao.Railways, iron-hulled ships, large factory buildings with all-steel frame structures, reinforced concrete buildings, complete sets of industrial equipment...all are no problem.

With a massive supply of steel, the industrial production of the Crossing Group can get rid of the current small-scale almost processing plant-like scale and embark on the road of real large-scale industrial production.
