There must be a difference between turning 3oC water into steam and 8oC water into steam. =Tong guò economizer, which is not much better than heating, makes the huge amount of smoke waste waste to spill the residual heat, which is really the crystallization of human wisdom.

So the question is, heating manufacturing is a basic thing that can no longer be basic, can it still make flowers?

The answer is yes.

Great people always go in different directions, Einstein can simplify the unwritten formula to e=mc2, Goldbach can also make 1+1=2 so complex that it would take people two centuries to prove.

So even if it is an economizer, there is still a lot of room for effort.

Great men are eager to reveal the truth to the public, while businessmen, on the other hand, spend their lives trying to bring it to their graves.

The H-fin economizer is one such thing.

Before the advent of this new economizer, power plants used a conventional plain tube economizer, which was no better than heating in terms of piping construction, and in this situation, the British were the first to see the opportunity contained in this.

They transformed the ordinary U-shaped or serpentine-shaped light pipe into an H-shaped fin tube, or ribbed tube, butterfly tube, so as to increase the heating area, but also make the water pipe denser, and achieve a more efficient coal saving effect. Due to its scientific construction and welding process, it also has the anti-wear performance, ash accumulation distance, structural tightness and flue gas side resistance that completely surpass the traditional economizer.

More than 30 years have passed since the new economizer was put into production, and the resourceful British have succeeded in blocking the technology. Focus on exports, muffled money. At this time, there are several new power plants in China that have adopted the design of this economizer, and the advantage of coal consumption is indeed obvious, but the cost consumption is more obvious, except for the situation that there is no money to spend in the design and construction stage of the power plant, basically no power plant will use this expensive economizer, after all, the price is hundreds or thousands of times that of ordinary economizers.

But now the situation has undergone subtle changes, China's power industry has entered the end of the leap forward exhibition, after the barbaric construction period, into the embryonic state of scientific sustainable exhibition.

Of course, none of this matters. It's the leaders who matter. There is a requirement for coal consumption.

The use of this new type of economizer is undoubtedly a simpler and more crude method than any project, without considering the cost, the thermal efficiency of H economizer is 2o percentage points higher than that of the light pipe. If you do the math. This is equivalent to energy saving of about 12%. Converted to the current coal consumption of 4oog, that is a full 8g.

This is not to mention the role of environmental protection and safe production.

However, once you consider the cost, it is not fun, 8G and the equipment cost of millions at every turn. There is no doubt that there is a stark contrast. Take the Jibei Power Plant as an example, if several units are replaced with this kind of economizer, the one-time investment will be tens of millions, and it will take three or five years to return to the cost.

Although three or five years is nothing in terms of the life of the power plant, the investment of tens of millions of dollars is definitely a terrible expenditure.

Therefore, at this stage, the H-type economizer is still a heavenly building.

However, the engineers of the domestic wisdom and bravery, it is only a matter of time to overcome this technical blockade, about ten years later, several power equipment manufacturers finally succeeded in this matter, although the quality is somewhat different from the British, but in the end it is H-shaped, and the price is less than 1/1O of the British.

At that time, this kind of economizer has only reached the popularization stage, power plant transformation, new power plant construction, non-H use.

Zhang Yifu, who has realized this, is quite eager to try.

So the question is, what kind of technical obstacles have stuck us for more than ten years?

Zhang Yifu probably studied a circle, H economizer is really interesting in structure, dense fin design is not a glance can be seen, pipes interspersed in it, in a limited space almost perfect interpretation of what is called excellence. After looking at the design drawings, Zhang Yifu was really dizzy, and it took more than two hours to understand the internal structure and welding points, in the final analysis, this is still a heating, not a tall design, but it is very ingenious in details and concepts, which is what makes people admire.

But Zhang Yifu's profession is not industrial design, he always feels that if a professional engineer dissects this economizer, it should not be difficult to restore a design drawing, and it will take 1o years for me to get this thing in a big country?

So Zhang Yifu's puzzle turned to another thing that seemed difficult, which was called flash resistance welding.

This is undoubtedly something that Zhang Yifu does not understand at all, and needs to find professionals for consultation, the welding process seems to be a deep pit, but no matter how deep it is...... This is just welding a radiator, and Zhang Yifu does not believe that this process will delay more than ten years.

In the final analysis, he believes that he still attaches great importance to the problem of Cheng dù, and has not paid much attention to consumption reduction in China, only focusing on production, and most of the professional talents and leaders also use their energy and ability on how to improve production and production efficiency, and no one has the time to study this kind of thing.

But after entering the 21st century, environmental problems, resource issues on the table, the power system has also been reformed, profit and loss at your own risk, along with this trend, the focus of investment of business enterprises will undoubtedly be deflected, and the small thing of economizer has finally been targeted, so any technical blockade can not resist the power of the cottage, and it will be completed in a short time!

Zhang Yifu couldn't help rubbing his hands, after warming his hands, he was more than ten years ahead of others and threw himself into the ranks of the cottage army.

In the next three days, Zhang Yifu arranged for Wen Tianming to work in the guest house, drafting the outline of the follow-up texts, and he completely stayed at home to make drawings, or rather, according to the cat and the tiger.

During the three days of retreat, the empty bed in the guest house was not idle. Zhao Hongqi has come to Jijing, and has become the first and only project manager of Hengdian Engineering Construction, forcibly tutoring Xiaofei in his Mandarin during the day, and going to the guest house to share a room with Wen Tianming at night.

At noon on the fourth day, when Xiang Xiaofei was teaching Zhao Hongqi about contracts and negotiations, he saw a man rushing out of the inner room, holding a pile of printer paper in his hand, his head unkempt, and shouting.

"Lao Tzu has finally completed !!" (to be continued!)
