Under the elevated factory building of the gas plant, more than a dozen cylindrical gas generators stand on cast reinforced concrete bases. The gas generators are sealed with water jackets, and the gas pipelines have been installed on the iron supports of the elevated factory building.
, the gas pipeline is made of cast iron, and the joints are sealed with water glass mixed with porcelain powder - this is currently their best anti-corrosion sealing material. The huge demand for porcelain powder in Lingao has led to the rise of new products in Guangdong and Fujian.
Industry: Purchasing broken porcelain pieces. The porcelain that was broken or damaged during the firing process in the kiln factory used to be discarded directly. Now there are businessmen who specially buy it, pack it and transport it to Lingao. The industrial department then grinds the broken porcelain pieces with a ball mill.
Crush into fine powder and set aside.
The valves and flow instruments are self-produced by Lingao, and the quality is not very guaranteed. Therefore, the entire factory is fully open to maximize ventilation and avoid leaks that may cause casualties.
"What's the problem?" Jiang Ye jumped out of the car and first took a look at the birdcage hanging at the door of the workshop - they didn't have special chemicals that could be added to the gas as a warning smell, so they could only use it wherever there was gas.
The simplest bird test method. The bird inside looks very lively and has no special state.
"The outlet temperature of No. 4 furnace has risen too fast!" the foreman said in a panic and handed over his work record book. He used to be a kiln worker and had a unique skill. He could see what the temperature was in the furnace.
You can tell the color of the thermometer. However, since arriving in Lingao, his skills have been replaced by industrial thermometers. Although his secret method is worthless, his work experience is still useful, so he was trained as a foreman.
he
Jiang Ye glanced at his work record book and looked at the situation inside the furnace through the observation window - in fact, he didn't know much about gas generators, but he had learned a lot of techniques in this area unexpectedly.
"It should be running sideways." Jiang Ye said. The so-called side running means that the ash layer in the furnace is high on one side and low on the other side, and the fire layer is also skewed at the same time. The high side is running hot and hot, and the low side is dark and cold.
“Test the gas quality under test!”
Part of the gas generated in the furnace was directed to the special test combustion port of the branch pipe. They did not have the equipment to measure the gas content, so they had to use the simplest visual combustion method to roughly test several main components in the gas.
"Report! The carbon monoxide level has dropped! The carbon dioxide level has increased!" a student who was practicing at the construction site loudly reported.
"Bring the stove rod. Go up to the top of the stove and poke the ashes!" Jiang Ye greeted, and someone immediately brought the special stove rod over. "You guys, use the hook to pull the ashes from the ash pan and get out the ashes!"
Jiang Ye first broke open the accumulated high ash layer and lowered it. Then with the following removal of ash, a lot of ash residue was removed. Even with visual inspection, it can be seen that the carbon content in the ash is relatively high, which shows that he is correct about the fault.
His judgment was basically correct. After removing the ashes, he asked the workers to use iron drills to compact the areas where the material layer burned fiercely, and added some materials appropriately to keep the material layer in a uniform state.
After a while, the temperature of the air outlet and the quality of the air returned to the normal range. The fault was eliminated. Jiang Ye knew that this was the simplest fault in the gas generator, but it was also the most common. Chuan Chuan Group uses gas generators
It has a considerable scale, but the problem of shortage of experienced manpower has never been solved. Even important projects such as steel plants cannot get enough skilled manpower.
He looked at this group of people and found that except for the foreman, no one had experience in operating a gas generator. Training work still had a long way to go. When problems came up, the foreman himself was blinded.
Jiang Ye first briefly analyzed the cause of the failure, how to deal with it and why it should be dealt with in this way. These are very simple things. As long as there is a master with it, a group of skilled workers can be brought out quickly, but now "
"Master" himself is not very reliable either.
Solving the fault is one thing, and you also have to find out the cause of the fault. Jiang Ye knew from the technical manual of the gas generator that there are not many factors that cause eccentric operation. In addition to coking in the furnace, there is a problem with the charge. Judging from the situation just dealt with
, the coking in the furnace was dealt with in a timely manner.
Jiang Ye pinched a handful of coal particles in a basket - the gasifier uses a variety of fuels, and what is used here is the washed coal from the coal washing plant, which is the pulverized coal dust precipitated in the coal washing wastewater.
After collection, drying and grinding.
The coal powder felt a bit wet in the hand, with too much water content. Jiang Ye gave the first reason in his mind.
"Look, this coal powder is too wet." Jiang Ye opened his clenched fists, and the coal powder fell into small clumps. "If there is too much moisture, the charging will be uneven, causing the furnace charge to be uneven. So like this
The raw materials must be mixed in time after loading." He glanced at it and asked, "Who is loading today?"
"I-" A worker raised his hand hesitantly.
"Why don't you follow the specifications in the operation manual?" Jiang Ye said sternly, "If you are lazy, something will happen! You didn't mix evenly today and a malfunction occurred. In a light way, it will affect production. In a serious way, if it is not dealt with in time, it will
It will burn through the furnace body and cause a major accident! You will not regret your own death, and you will also give up the lives of your co-workers!"
The unlucky worker was so frightened that he could not utter a word - the word "death is not a pity" is too lethal. If Lingao was not a "new society" now, he would have knelt down and begged for mercy.
"Deduct his work points according to the regulations!" Jiang Ye said to the foreman, "Have a team meeting after get off work and help him properly."
In addition to commune members, all naturalized workers and employees have also begun to implement the work point system. However, this kind of labor remuneration is much more complicated than the labor cents obtained by members participating in work assignments. The HRs among the elders have already begun to formulate and implement a system.
The complex compensation system includes the calculation of fixed wages and bonuses, additional benefits, and compulsory work-related injury and labor insurance. This system is based on the calculation system of "work points".
"Yes, yes." The foreman nodded repeatedly.
The foreman failed to fulfill his supervisory responsibilities and was deducted points. The leadership responsibility system is in the promotion stage: since leaders get more remuneration and receive more benefits than ordinary workers and employees, they also have to bear more responsibility.
On the way back to the headquarters, Jiang Ye took the time to write down the entire process of handling the fault today in his work notebook. Then he wrote down a memo to send to the fuel management department - coal less than 10mm.
Do not use powder as a raw material for gasification. It is better to continue to make briquettes. There is also the issue of moisture content. It is normal for coal to have high moisture content. At least it needs to be dried for a few days.
The overhead gas pipeline extending from the gas workshop extends to the open hearth workshop. Most of the overhead base used to support the pipeline is made of bricks. Among the brick pillars are wrought iron pillars to increase the strength of the entire base. Looking at the work
People carried mud buckets and used trowels to lay bricks one by one. Jiang Ye sighed: If there is enough steel, the steel bracket of the welded structure will be good. It is easy to build and strong. Nowadays, in this kind of industrial life, people are replacing melons and vegetables.
When will it be over? Steel is the skeleton of industry. Without enough steel, Lingao's so-called modern industrial system will be like suffering from rickets and cannot exert its full strength.
He thought of the discussion about the mixing furnace at the technical seminar of the iron and steel complex in the previous stage. At that time, some elders of the mechanical and metallurgical departments believed that the mixing furnace was an important process equipment in the open-hearth steelmaking method and should be included in the manufacturing process.
Project. The so-called mixing furnace is a device mainly used to adjust and balance the supply and demand of molten iron between the blast furnace and the converter to ensure uninterrupted supply of the molten iron required by the converter. The molten iron is stored and mixed in the mixing furnace to evenly mix the composition and uniform temperature of the molten iron.
It is very beneficial to converter steelmaking. With the mixed iron furnace, the molten pig iron in the blast furnace can directly enter the open hearth for steelmaking, eliminating the need to first cast it into iron ingots and then use the iron melting furnace to melt it during steelmaking, which can save a lot of money.
of fuel. Give full play to the advantages of continuous production.
However, in terms of specific manufacturing, the robot found that it had to manufacture a mixing furnace with a capacity of 50 tons of molten iron, and it also had to be able to move and turn over. There were a series of difficulties in the manufacturing of many key moving parts, and in the end it was decided not to use them.
Economical but simple pig iron ingot smelting process - wait until the materials are improved in the future before purchasing.
This problem fully exposed the shortcomings caused by the lack of materials. Jiang Ye thought that if the metallurgical department was not able to ensure the supply of steel with sufficient grades, it would not be completely impossible to manufacture these parts. Fortunately, the iron mixing furnace is only an improved auxiliary equipment, not an
Decisive production equipment.
The new steelmaking workshop of Lingao Steel Company no longer uses the converter steelmaking method in the past, also known as the Bessemer steelmaking method. Instead, it adopts the more efficient Siemens-Martin steelmaking method-the open-hearth method. The open-hearth furnace not only
Open hearth furnaces can be used in the steelmaking industry, glass industry and other smelting industries. It is a process with high production efficiency.
Open-hearth steelmaking is a large-scale steelmaking method in which raw materials such as pig iron, scrap steel, high-grade iron ore, etc. are melted and refined into molten steel using an open-hearth furnace using gas as fuel and directly heated by a combustion flame. In the old days, it was
The main steelmaking method still used until the 1960s, its production efficiency and steel quality were far higher than the traditional Bessemer converter method. The basic working principle of the open-hearth furnace is heat storage, and it does not require the construction of an additional regenerator - its
It has a regenerator itself.
In the converter steelmaking method, the heat required for smelting comes from the smelting process itself, that is, the heat generated by the chemical reaction of the charge. The open-hearth method requires heat from the outside. Simply put, it is efficient, controllable and relatively clean.
