The Spring Festival is approaching.

Suiren Company, which has just opened the Cloud Inspection Expo, has all its subsidiaries entered a busy state.

Huaneng Group sent a professional team of engineers and a vice president in charge of business negotiations to Texas.

Recently, he happened to be in Changfuguo, Shandong Province, and received the other party.

Both sides came to Huaneng's thermal power plant in Texas.

Inside the thermal power plant, Snail Industry and Hua Energy Group are clearly distinguished because Snail people wear anti-virus helmets, while Huaneng wears masks and safety helmets.

Many Huaneng employees show envious expressions. A virus-proof helmet worth more than 300 is unwilling to provide employees with them. Even state-owned enterprises have only a few positions.

After more than half a year of renewal, several series have been developed, which can be used as masks, motorcycle helmets, and gas masks.

Especially for those spray paint, miners, etc., many people have purchased special anti-virus helmets at their own expense.

Wang Shuo, deputy general manager of Huaneng, pointed to the steam turbine generator set in front of him: "Mr. Chang, can the temperature difference power generation module be cheaper? Our dozens of thermal power stations all need the temperature difference power generation module transformation, and we are all old friends."

Chang Fuguo did not intend to give in too much: "Mr. Wang, you get what you pay for. It's already very discounted. You can tell by calculating it. This is cheaper than adding a steam turbine generator set."

After all, the energy conversion efficiency of coal-fired steam turbine generator sets in thermal power plants is usually only 40%. If it is a supercritical steam generator set, the limit efficiency is about 49%. If it is a circulating gas reincarnation generator set, the limit efficiency is 58%.

I heard that Siemens abroad is developing a new combined cycle gas generator set with an efficiency of 60%.

Huaneng, a Texas thermal power plant, has a thermoelectric conversion efficiency of only about 40%, and about 60% of its energy is wasted. Although some waste heat can be used to heat nearby residents in winter, the efficiency is still not high throughout the day.

Wang Shuo and Huaneng’s engineers estimated the effect of over-temperature differential power generation system. Calculated based on 60% of waste heat, they believed that the thermoelectric efficiency of 24% of the temperature differential power generation can improve the overall efficiency of 14.4%.

After the transformation of temperature differential power generation, the coal-fired generator sets in ordinary thermal power plants can increase the efficiency to about 54.4%, which is even more beautiful than supercritical generator sets.

Faced with such a unique business, Wang Shuo really didn't have much room to bargain, so he could only agree to Chang Fuguo's price: "Okay!"

The temperature difference transformation price of snail industry is calculated based on the type of generator and installed capacity. Generally, coal-fired generator sets cost about 15 million to 100,000 yuan per megawatt, and a 300 megawatt generator set costs about 15 million to 30 million yuan.

This is already the result of the discount on Snail Industry, otherwise it would not be an exaggeration to double the price and it may not be possible to buy it.

"By the way, Mr. Chang, our project is ready, and we're waiting for your equipment."

Chang Fuguo nodded: "Don't worry, the equipment is almost done. Your venue is ready and can be transported to Ning District after the Spring Festival."

"The site must be ready. The power plant will be prepared in 2007. If it weren't for this upgrade and renovation, it would have been possible to invest in power generation long ago." Wang Shuo said with a smile.

Chang Fuguo is very concerned about this matter. This is a new energy project that Snail and Huaneng cooperated with. He thought about his work schedule and then said:

"I will go there myself at that time. After all, it is the first cooperative project. Maybe all coal will be converted to gas in the future."

"We really envious of your technology." Wang Shuo looked envious. Many of the technologies of Suiren Company are unimaginable black technology for many companies, and one of them is enough to make a fortune.

Chang Fuguo smiled but said nothing. Every employee of Suiren Company is proud of his company's technology.

The group continued to walk into the power plant and came to a generator set that was being upgraded.

Since half a year ago, the five major domestic power generation groups have reached cooperation with Suiren Company. At first, they cooperated with pollutant treatment and then in-depth cooperation in power generation technology.

The generator sets that are being transformed in front of us no longer use coal-fired generator sets, but instead use gas turbine generator sets, which is also a new direction in the domestic power generation industry.

After cooperating with Suiren Company, Huaneng Group made great progress, and the other four power generation groups were still slowing down. Huaneng has already carried out several projects.

Dezhou Thermal Power Plant is a, and the Weizhou Power Plant in Ning District is also a new energy project.

"Mr. Chang, we still produce this gas engine ourselves."

“How efficient?”

When asked about efficiency, Wang Shuo was somewhat embarrassed: "Single-level efficiency is 33%, and cyclic combustion is 44.6%.

Chang Fuguo raised his eyebrows. He had known that the domestic heavy-duty gas turbines were inefficient, but he did not expect that they were so low.

General Electric (not the same as General Motors), Siemens, Mitsubishi, and Ansardo, usually has a single-stage combustion efficiency of 40% and a cycle combustion efficiency of about 58%.

By comparison, the gap is so huge.

"You and Institute 703 did this?" Chang Fuguo doubted their ability in his tone.

Wang Shuo was also very embarrassed and hurriedly explained: "This is improved by the old model with mature technology, and it can only reach this level. The new model is still being tested and the effect is pretty good."

"Good? How much test data?"

"Single-level 36%, cycle 48%." It was really embarrassing, and Wang Shuo could only answer with a tough bullet.

Chang Fuguo was speechless: "It's not that they cooperated with Baosteel. They had done nano powder metallurgy some time ago. The material performance should be able to meet the needs, right?"

"It is because the materials are good that the improvement is so fast, otherwise it will not be so fast, mainly because there is too much talent gap and no orders."

Chang Fuguo shook his head: "So our chairman is right. No matter how bad the domestic products are, they must maintain market share. Otherwise, there will be no market. I guess the state of 703 will be half dead."

"This is also impossible. In the past, domestic products were too bad, and the market-oriented reform was too fast, so many things were killed by foreign companies without time to protect them." Wang Shuo also looked helpless.

"Support 703 companies as soon as possible! No matter how good the foreign goods are, safety is ultimately a big problem." Chang Fuguo also had a headache.

"Don't worry, now with your technology, our buffer time can allow the 703 Institute to gradually improve the performance of domestic gas turbines."

Half a year ago, when Suiren Company and the five major power generation groups planned to promote new energy projects, Suiren Company refused to use General Electric's gas turbines and required that domestic gas turbines must be used.

For this matter, both sides grind their teeth for more than a month and finally adopted a compromise plan. In the early stage, half of the generator sets were given to domestic gas turbines. Then, as the performance of domestic gas turbines improved, the market share was gradually given to domestic gas turbines.

Since there were no suitable enterprises in China at that time, the gas turbine company of Datang Power Generation Group was mainly invested by 703 units, five major power generation groups and Suiren Company to establish the Beifeng Gas Engine Company.

After inspecting this old-fashioned gas turbine, Chang Fuguo was really disappointed, but he had no choice but to rely on the temperature difference to generate the comprehensive efficiency of deadlifting.
