It is inevitable that the ability to turn 30c water into steam and 80c water into steam is different. = Through the economizer, which is not much smarter than heating, the huge waste of smoke exhaust can exert waste. This is actually the crystallization of human wisdom.

So the question is, heating manufacturing is something that cannot be more basic, and can it still make flowers?

The answer is yes.

The development directions of great people are always different. Einstein can simplify the unspeakable formula to e=mc2, and Goldbach can also complex 1+1=2 so that it takes people two centuries to prove it.

So even economizers still have a lot of room for effort.

When great men discover the truth, they can't wait to make it public, while merchants are just the opposite. They will work hard to bring this discovery into the grave for their entire lives.

H-type fin economizer is such a thing.

Before this new economizer appeared, power plants used a conventional light pipe economizer, which was not as good as heating in pipeline structure. Under this situation, the British discovered the opportunities contained therein.

By transforming ordinary U-shaped or serpentine light pipes into h-shaped fin tubes, or rib fin tubes and butterfly tubes, they increase the heated area and make the water-through pipes more dense, achieving a more efficient coal-saving effect. Due to its scientific structure and welding process, it also has anti-wear properties, gray accumulation degree, structural density and flue gas side resistance that are completely superior to traditional economizers.

This new economizer has been put into production for more than 30 years. The clever British people have successfully blocked this technology, focused on exports, and made a fortune in silence. At this time, several new power plants in China adopted the design of this economizer. The coal consumption advantage is indeed obvious, but the cost consumption is even more obvious. Except for the situation where there is money and nowhere to spend during 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 a leap forward development. After the period of barbaric construction, it has entered the budding state of scientific and sustainable development.

Of course, this is not important. What is important is that the leaders have begun to have requirements for coal consumption.

Using this new economizer is undoubtedly a simpler and rough method than any project. Without considering the cost, the thermal efficiency of the economizer is 20 percentage points higher than that of the light pipe. If you calculate it roughly, it is equivalent to saving energy by about 12%. Converting to the current coal consumption of 400g, that is 8g.

This has not yet talked about its role in environmental protection and production safety.

However, once the cost is considered, it is not fun. 8g and equipment costs are undoubtedly a sharp 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 to five years to pay back the cost.

Although three to five years is nothing to say about the life of the power plant, a tens of millions of dollars is definitely a terrible expense. Which leader has given you so much money to wait for you to recover in five years?

Therefore, at this stage, the H-type economizer is still a tower in the sky.

However, it is only a matter of time for domestic engineers who are both smart and brave to overcome this technology blockade. About ten years later, several power equipment manufacturers finally successfully handled this matter. Although the quality is somewhat different from that of British people, it is actually H-type and the price is less than 1/10 of that of British people.

By then, this kind of economizer has reached the stage of popularization, power plants are renovated and new power plants are built, so it is not necessary to do so.

Zhang Yifu, who discovered this, was quite eager to try it out.

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

Zhang Yifu probably studied it for a while and found that the structure of the economizer is really interesting. The dense fin design cannot be seen through at a glance. The pipes interspersed in it, which almost perfectly interprets what it means to strive for excellence in a limited space. After looking at the design drawings, Zhang Yifu was really dizzy. It took more than two hours to understand the internal structure and welding points. After all, this is still a heating system, which is not a very high-end design, but it is very clever in details and concepts. This is what makes people admire.

But Zhang Yifu's profession is not industrial design. He always felt that if a professional engineer anatomizes this kind of economizer, it would be not difficult to restore a design drawing. It would take 10 years for our Yangyang copycat country to get this thing?

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

This is undoubtedly something that Zhang Yifu doesn't understand at all. He needs to consult a professional. The welding process looks like a deep pit, but no matter how deep it is... it is just welding a radiator. Zhang Yifu doesn't believe that this process will delay more than ten years.

In the final analysis, he believes that it is still a matter of importance to the degree. China has never paid much attention to consumption reduction, but only focuses on production volume. Most professional talents and leaders also devote their energy and abilities to how to improve production volume and production efficiency. No one has the time to study this kind of thing.

But after entering the 21st century, environmental problems and resource issues have come to the forefront, and the power system has also been reformed. We will be responsible for profit and loss. With this trend, the focus of business enterprises' investment will undoubtedly deflect, and the economizer is finally targeted. Therefore, no technological blockade can resist the power of counterfeits, and the work will be completed in a short time!

Zhang Yifu couldn't help but rub his hands. After warming his hands, he joined the ranks of the counterfeit army for more than ten years. What I copied was not the past, but the future.

In the next three days, Zhang Yifu arranged for Wen Tianming to work in the guesthouse and draft outlines of several subsequent documents. He stayed at home to make pictures, or to draw pictures. Regardless of whether the pictures can be used for manufacturing, people must first understand them, and the following will be easy to talk about.

During the three days of retreat and practice, the empty bed in the guesthouse was not idle either. Zhao Hongqi had already arrived in Jijing and gloriously became the number one in Heng Electric Engineering Construction and the only project manager. During the day, Xiang Xiaofei forced his Mandarin to tutor him, and at night he went to the guesthouse to live in the same room with Wen Tianming. After three days, he only met Zhang Yifu.

At noon on the fourth day, when Xiang Xiaofei orthodox Zhao Hongqi was on the contract and negotiations, a man rushed out of the inner room, holding a stack of printing paper in his hand, his hair was messy, and he shouted with his arms raised.
