Under the elevated building of the gas plant, there are more than 10 cylindrical gas generators on the reinforced concrete base of the casting haode, the gas generators are sealed with water jackets, the gas pipelines have been installed in place on the iron brackets of the elevated plants, the gas pipelines are cast iron, and the interfaces are sealed with water glass mixed with porcelain crushed dust - this is their most haode anti-corrosion sealing material at present. Lingao's huge demand for porcelain powder has led to the emergence of a new industry in Guangdong and Fujian: the purchase of broken porcelain pieces. In the past, the porcelain that was broken and damaged in the kiln factory was directly discarded, but now there are merchants who go to buy it and pack it and transport it to Lingao. The industrial sector then crushes the broken porcelain pieces into fine powder with a ball mill for later use.

The valves and flow instruments are self-produced by Lingao, and the quality is not very guaranteed, so the whole plant is fully open around the plant, so as to maximize ventilation and avoid casualties caused by leakage.

"What's the problem?" Jiang Ye jumped out of the car and first glanced at the bird cage hanging at the door of the workshop - they didn't have any special chemicals that could be added to the gas as a warning smell, so they could only use the simplest bird test method in all places where there was gas. The birds inside look very lively, and there is nothing special about the aftermath.

"The outlet temperature of furnace No. 4 is rising too fast," said the foreman in a panic, handing over the work notebook. He used to be a potter, and he had a good hand at what temperature the furnace was, and he knew by looking at the color of the fire. However, since arriving in Lingao, his hand jishu has been replaced by an industrial thermometer. Although his secret methods were no longer valuable, his work experience was still useful, so he trained him to be a foreman. he

Jiang Ye glanced at the work notebook and looked at the situation inside the furnace through the observation window - in fact, he didn't know much about the gas generator, but he had learned a lot about it.

"It should be biased." Jiang Ye said. The so-called partial operation means that the ash layer in the furnace is high on one side and low on the other, and the fire layer is also deviated at the same time, the high side is hot on the fire side, and the low side is dark and cold

The gas produced in the furnace was partially diverted to the special combustion port of the branch pipe - they did not have the equipment to determine the gas content, so they had to use the simplest method of combustion visual inspection to roughly examine the main components of the gas.

"Carbon monoxide levels have been reported to have decreased, carbon dioxide levels have increased," a student who was interning at the construction site reported aloud.

"Bring the stove rod. Go to the top of the stove to poke the ashes" Jiang Ye greeted, and someone immediately brought the special stove rod, "You guys, use a hook to pull the ashes from the ash tray and get the ashes out."

Jiang Ye first poked open the accumulated high ash layer and lowered it. Combined with the following ash, the ash is cleaned out a lot, and even if you look at it, you can see that the carbon content in the ash is high, which shows that his judgment of the fault is basically correct. After removing the ash, he took care of the workers to use an iron drill to tamp tightly in the place where the material layer burned violently, and added some materials appropriately to keep the material layer in a uniform state.

After a while, the temperature and quality of the outlet returned to the normal range. The fault is eliminated. Jiang Ye knew that this was the simplest fault in the gas generator, but it was also the most common. The gas generator used by the crossing group has a considerable scale, but the problem of shortage of experienced manpower has not been solved. Even important projects such as steel mills do not have enough skilled manpower.

He looked at the group of people, and except for the foreman, none of them had any experience in operating a gas generator, and there was still a long way to go in training. As soon as he encountered a problem, the foreman himself was blinded.

Jiang Ye first briefly analyzed the cause of the failure, the method of disposal and the way to deal with it. These are all very simple things, as long as there is a master with it, a group of skilled workers can be brought out soon, but the current "master" himself is not very reliable.

Solving the fault is one thing, but also finding out the cause of the failure. Jiang Ye knew from the Jishu manual of the gas generator furnace that there were not many factors that caused deviation in operation, except for the coking in the furnace, there was a problem with the charge. Judging from the situation just disposed of, the coking in the furnace has been treated in time.

Jiang Ye pinched a handful of coal pellets in the basket - the gasifier has a variety of fuels, and here it is the tank coal after coal washing from the coal washing plant, that is, the coal dust precipitated from the coal washing wastewater. It is collected, dried and milled.

The coal dust seems to be a little wet in the hand, and the water content is too high. Jiang Ye first gave the first reason in his heart.

"You see, this coal is too wet." Jiang Ye parted his clenched fists, and the coal dust fell down in small clumps, "If the moisture is large, the charging will be uneven, causing the charge to be uneven." Therefore, such raw materials must be beaten in time after loading. He swept his gaze, "Who is loading today?" ”

"I—" One of the workers hesitantly raised his hand.

"Weishenme doesn't follow the specifications in the operating manual?" Jiang Ye said sharply, "If you are lazy, you will have an accident, you didn't fight well today, and if you break down, it will affect production, and if you don't deal with it in time, it will burn through the furnace body, causing a major accident, and you won't even have to give away your own lives."

The unfortunate worker trembled with fright, and could not utter a word -- it is not a pity that death is too lethal, and if it were not for the fact that Lingao is now a "new society," he would have knelt down and begged for mercy.

"Deduct his work according to the regulations," Jiang Ye said to the foreman, "hold a team meeting after work, and help him well." ”

In addition to the members of the commune, all naturalized migrant workers and clerks also began to implement a system of labor sharing, but this kind of labor remuneration was much more complicated than that of the members who participated in the dispatch to obtain the labor allowance. Among the veterans, HR has begun to develop and implement a complex compensation system, including the calculation of fixed salaries and bonuses, additional benefits, and mandatory work-related injury and labor insurance. And this system is built on the calculation system of "division of work".

It was a long and long nod.

The foreman was also deducted points for failing to fulfill his supervisory responsibilities. The leadership responsibility system is in the process of being promoted: since leaders are paid more and benefit more than ordinary workers and employees, they also need to be more responsible for their responsibilities.

On the way back to the headquarters, Jiang Ye took the time to write down the entire process of dealing with the fault in his work notebook, and then he wrote down a memorandum to be sent to the fuel management department - coal powder less than 10mm should not be used as a raw material for gasification, and it is better to continue to make briquettes. There is also the problem of water content, it is normal for the water content of the trough coal to be large, and it is better to dry it for a few days.

The overhead gas pipeline extending from the gas workshop extends to the open-hearth workshop, and most of the overhead pedestals used for the support pipelines are made of bricks, and the wrought iron columns in the middle of the brick columns are used to increase the strength of the entire base. Looking at the workers carrying mud buckets and holding mud knives to lay bricks piece by piece, Jiang Ye sighed: If there is enough steel, the steel bracket of the welded structure is good, and the construction is trouble-free and strong. At present, when will the days of this kind of "melon and vegetable generation" engaging in industry be over? Steel is the skeleton of industry, and without enough steel, the so-called modern industrial system of Lingao is like suffering from hypochondriasis and cannot exert its full strength.

He thought of the discussion about the iron mixing furnace at the jishu seminar of the iron complex at the previous stage. At that time, some of the patriarchs of the mechanical and metallurgical ports believed that the iron-mixing furnace was an important process equipment in the open-hearth steelmaking method and should be included in the manufacturing project. The so-called iron mixing furnace is the equipment that is mainly used to regulate and balance the supply and demand of molten iron between the blast furnace and the converter, to ensure the uninterrupted supply of molten iron required by the converter, and the molten iron is stored and mixed in the iron mixing furnace and the uniform temperature of the molten iron, which is very beneficial to the converter steelmaking. With the iron mixing furnace, the molten pig iron in the blast furnace can directly enter the open-hearth furnace for steelmaking, eliminating the need to cast iron ingots first and then melt them in the iron furnace when making steel, which can save a lot of fuel. Take advantage of continuous production.

However, in terms of specific manufacturing, the mechanical port found that to make a mixing furnace with a capacity of 50 tons of molten iron, it also needed to be able to move and flip. There were a number of challenges in the manufacture of many critical moving parts, and the decision was eventually made to use the less economical but simple process of smelting pig iron ingots – waiting for the materials to be improved in the future.

This problem fully exposes the shortcomings caused by the lack of materials. Jiang Ye thought that if it weren't for the metallurgical department's inability to ensure the supply of sufficient steel grades, it would not have been impossible to manufacture these parts. Fortunately, the furnace is only an auxiliary equipment for improvement, not a decisive production equipment.

The new steelmaking plant of Lingao Iron and Steel Company no longer uses the converter steelmaking method of the past, the so-called Besaimai steelmaking method. The more efficient Siemens-Martin steelmaking method - open-hearth method - was adopted. Open-hearth furnaces are not only used in the steelmaking industry, but also in the glass industry and other smelting industries. It is a highly productive process.

Open-hearth steelmaking is a large-scale steelmaking method that uses open-hearth furnace gas as fuel to melt and refine raw materials such as pig iron, scrap steel, and high-grade iron ore into molten steel under the condition of direct heating by a combustion flame. In the old space, it was the main steelmaking method that was still in use until the 1960s, and its production efficiency and steel quality were much higher than that of the traditional Bessemel converter method. The basic principle of operation of an open-hearth furnace is heat storage, and it does not require a separate regenerative chamber - it has its own regenerative chamber.

In converter steelmaking, the heat required for smelting comes from the smelting process itself, i.e. the heat generated by the charge during the chemical reaction. The open-hearth method requires heat to be provided by the outside world, and in simple terms, it uses an efficient, controllable and relatively clean gaseous fuel - coal gas.
