Lijiazhuang, a factory that manufactures boilers. Shang Wu and Jia Xu are looking at the manufacture of boilers here.

This is the early boiler, and the later boiler, it seems very rough, even, in many places, can not be called a boiler, the reason is that most of the boilers, the use of rivet joint, the rest of the use of casting process. Judging by the technical standards of martial arts, there is a lot of room for technological progress, but it is far from being advanced.

Boiler equipment was first used in steam engines, but it was a contradictory and partial casting process. Moreover, a large number of pipes are used, and the cost remains high, which is not something that the average family can afford. This requires higher-level commercial organizations to afford such a large cost, as they are willing to provide such a high cost for such a new technology.

"There are currently two kinds of boilers we produce, one is this riveted type, and the main customer groups are those high-level commercial organizations in Handan, as well as luxury hotels." The person in charge of the factory said.

Shang Wu and Jia Xu nodded and listened carefully to the introduction of the person in charge. From time to time, Jia Xu raised some opinions, doubts, or suggestions for improvement, although he was not very familiar with technology. But this does not prevent him from proposing the meaning of improvement through the enjoyment of heating equipment.

As the weather gets cooler and cooler. Winter is just around the corner. Preparations for winter heating have been completed in the entire area controlled by the Republican Army. Of course, there are also some high-level heating equipment renovations in progress.

That's right, it's a heating makeover.

In the past winter, there were some inevitable freezing deaths and deaths in the areas controlled by the Republican Army, after all, the control of the Republican Army at that time was relatively weak, and the local government's material mobilization was limited, such things inevitably happened, but with the rapid recovery of the Republican Army's economic strength, the problem of heating in winter was once again placed in front of Shang Wu and Jia Xu.

"This kind of production output is not too high, I want to know, how much can the boiler made by casting method produce?" Shangwu asked. For new boiler equipment, the current state of development is not enough. Because this kind of high-priced stuff can't meet the needs of most people. In contrast, Shang Wu was more concerned with the productivity of another product with backward technology and a very rough appearance, because these things could meet the needs of the Republican Army to the greatest extent.

"This kind of cast boiler is very fast, in the beginning, we can only produce more than 100 units a month, but now, we have expanded the scale, plus the cooperation with Handan Iron Works, we can now produce more than 10,000 units a month, and the output will be higher in the future." The person in charge said excitedly.

Shang Wu is still very satisfied. Compared with the former, the latter method can meet people's needs, but it also has many disadvantages. His energy consumption is still extremely coarse. But it can meet their production needs. This is what Shangwu should pay attention to the most.

This kind of boiler equipment made by casting process is simple and fast to manufacture, it does not look like a boiler, it seems to be a very large furnace and a water tank.

The most expensive part of the whole boiler is the water tank, because it is molded by one-time casting, and many places do not even need to be polished, and human hands can feel the extremely rough feeling.

Coal is used for heating in stoves, and wooden, bamboo, or even paper chimneys are used in homes to exhaust smoke. Actually, it's a stove, because most of the households, who don't have much of the ability to pay, put more heating in the other rooms.

However, this boiler equipment greatly meets the heating needs of the people, which can make them not too cold in winter.

This is the average family, and some families cannot afford to buy such boiler equipment, because it will cost them two months' salary, if you add the burning of coal, it will add up to more than four months' salary, if you burn more, it will be more than five months. This is not something that the average family can afford.

So, some families buy stoves. The stove is simple, and the most important thing is that the smoke exhaust equipment can be done. What Shang Wu didn't know was that in Luzhou, as well as some areas in Hedong, in addition to some of the above-mentioned exhaust chimneys, they also used another kind of exhaust chimneys, bulky cement chimneys.

The characteristics of cement have penetrated into the people in these areas, and most people are reluctant to buy too much paper chimneys that are more expensive and frequently replaced, after all, it is better to let them buy some food than to waste the money to buy chimneys.

As long as the boilers for heating are used intensively in Handan, because it is the most important economic area controlled by the Republican Army, and the economy there is extremely developed, they are fully able to withstand such new equipment, no smoke, clean and warm. If the insulation is good enough, the ordinary room will be as warm as in summer. This has never been done before.

And such warm hours on the basis of a large amount of coal mining.

Since the beginning of the summer, people have been actively stockpiling coal. In addition to this, a large amount of coal has been transported in Hexi Prefecture and the newly occupied areas such as Bingzhou, after all, the winter cold is very deadly, and the necessary heating and insulation equipment was extremely lacking in ancient times.

"With these, we can spend the winter very well. This is a great progress for us, and under such progress, our development will be much more beneficial. The advent of heating will ensure that our people can survive the cold winter to the greatest extent. This is an extremely favorable outcome for us. Jia Xu said.

"Well, we only see ordinary people, we also need to care about the front line, the heating problem on the front line must also be solved, and at the same time, we must do a good job of related rotation work, I think, we should be clear about this, because this is still extremely beneficial to us." Shang Wu said.

The use of coal for heating, can ensure the safety of people's lives to the greatest extent, every cold winter, for the lives of ordinary people, is a huge test, cold, disease, will lead to a considerable number of people death, or serious illness. This is a difficult situation for Shangwu to accept.

Therefore, in the winter of this year, large-scale promotion of heating is a necessary measure, which will greatly ensure the safety of people's lives.

"I'm worried that it won't be promoted in the state. Because of the demolition of the city wall, Jinyang City was in an uproar, and the two sides discussed it very much. Shang Wu said worriedly that although the republican army is doing very well, the problem is that the people of Jinyang lack trust and lack of security awareness.

"The main thing is that we have to take on the corresponding defense and security, on the one hand, we need to strengthen the defense of the north, the military reform of the independent infantry division is wrong, at least not too successful, I think we should reorganize the independent division and bring the local partisan units and other armed forces into it. In addition, there is also the establishment of a corresponding militia system and the establishment of various fortresses, so that the safety of Jinyang can be guaranteed to the greatest extent. Jia Xu said, Shang Wu nodded in agreement.

"Well, so to speak, but to do this, there are still a lot of things that we need to do clearly for our difficulty, and if we want to accomplish all kinds of things, the first guarantee is safety, and the second is their warmth. Finally, there is their food supply. Shang Wu believes that three key points need to be developed at the same time.

"Well, our peace talks with the Wuhuan people are still in communication, and we still need to continue to strengthen our defenses." Jia Xu reminded.

Shangwu nodded in agreement. In fact, every time the IRA occupies a new area, it integrates the local armed forces, which, after all, are very chaotic. The IRA has to integrate the local armed forces after each battle, which is an important basis for ensuring the security situation in the local area and the stability of the economic order.

The annexation of a state is not a very simple occupation, more often, it requires more other aspects of governance, as well as extension, which requires a certain military foundation to do such a thing.

Things didn't go very smoothly with the annexation of the state, but everything was in the IRA's plans.

In Handan, the securities exchange market. Stocks related to coal and transportation have risen rapidly, and after a certain period of time, this situation still greatly satisfies various needs.

The increase in consumption brought about by heating, the more coal mining, the more enterprises earn, in such a situation, their development trend is still extremely favorable, which is the most favorable result for them at present, as well as the development of demand.

"Did you hear that? Coal is only sold fast in our place, and in other parts of the Central Plains, the development is not very good, and many places are unlikely to accept our things. An investor said worriedly on the trading floor.

"Can't promote?" A lot of investors find it difficult to understand such a situation, in their opinion, it is a difficult thing to understand, they don't understand that coal can bring warmth, but the Central Plains don't accept it, they don't know why.

"It's incomprehensible that they think coal can kill them." Many investors are puzzled. They might be better off if those areas were expanded.
