Why is the whole world competing for gas turbines? What progress has been made with domestically produced heavy-duty gas turbines?

Quick Summary of the Key Points

This news reports on a significant milestone in China's high-end power sector: This year, domestically produced gas turbines have finally received large-scale overseas orders, marking a historic breakthrough for Chinese manufacturing. However, in the most technically challenging and profitable segment of the market—top-tier heavy gas turbines—we are still behind the global leaders consisting of General Electric, Siemens, and Mitsubishi Heavy Industries. We are accelerating our efforts to catch up. China Aero-Engine Corporation (CAEC), which is responsible for developing this technology, holds two core competencies: aeronautical engines and heavy gas turbines, both considered the “pearls of the industrial crown,” giving us a unique advantage in terms of technological interoperability.

Detailed Analysis

1. Understanding Gas Turbines: Not Just Bigger Gas Stoves, but the “Super Hearts” of Industry

Many people mistakenly think of gas turbines as enlarged versions of household gas water heaters or stoves, but their importance is far greater. They are powerful devices that use the high-temperature gas streams from natural gas to drive massive fans at high speeds. The output of a top-tier heavy gas turbine is equivalent to the combined power of thousands of small cars. These turbines are essential for critical applications such as large power plants, military ships, and overseas oil and gas pipelines. Previously, we couldn’t produce reliable products; we either had to pay significantly more for imported ones or face supply restrictions on national security grounds. The fact that we have secured overseas orders this year indicates that our products have surpassed the initial stages of development and have been recognized by international customers for their performance and stability.

2. Why Can’t We Catch Up with the Big Three in Heavy Gas Turbines?

There are only three companies in the world that can manufacture top-tier heavy gas turbines, and they have been accumulating technology for nearly 100 years. We have only started this journey in the past two to three decades. The gap is not something that can be bridged by simply copying blueprints. The core components of these turbines, such as the blades, must operate in flames over 1,600 degrees Celsius—more hot than magma—for tens of thousands of hours without failure. This means the engine must function flawlessly for over a decade at full capacity. Additionally, the thermal efficiency of top-tier gas turbines exceeds 60%, allowing them to generate nearly 20% more electricity from the same amount of natural gas, significantly reducing fuel costs. The advantages they have gained over decades include specialized material formulas, precise manufacturing processes, and extensive operational data from around the world. What we lack is the practical experience accumulated over this time.

3. CAEC’s “Two Pearls”: Connecting Aerospace and Heavy Industry

CAEC is often associated with aircraft engines, so it might seem surprising that it also develops gas turbines. The “two pearls” refer to aeronautical engines and heavy gas turbines, which share many core technologies, such as high-temperature-resistant blade materials, advanced fan designs, and coatings. By mastering aeronautical engine technology, we can easily adapt it for use in heavy gas turbines. Having both of these technologies in our hands means we have cut off the two main constraints that could hinder our progress.

4. The Breakthrough of Gas Turbines is Relevant to Everyone

This technological advancement is closely related to our daily lives. Importing gas turbines used to cost hundreds of millions of yuan, and replacing a single blade could cost hundreds of thousands. Now, domestic products are over 30% cheaper. With more domestic turbines used in power plants, electricity prices will decrease, potentially leading to lower household costs. Additionally, our own heavy-duty ships and amphibious attack vessels will have more powerful and faster propulsion, enhancing our maritime defense capabilities and increasing public safety. The export of gas turbines generates high-value revenue, which can boost the overall income of the industry and, in turn, improve the standard of living for everyone.

5. The Challenge is Not About Whether We Can Produce, but Whether We Can Operate Without Errors for Decades

While we can now produce qualified heavy gas turbines, the gap with the leading companies lies in their experience and reliability. Our current turbines have a lower thermal efficiency and fewer hours of operational data compared to the world’s best. Overseas customers, who rely on these machines for decades, are cautious about choosing untested products. By first using domestic turbines in our own power plants and industrial projects, we can accumulate operational data and gradually improve the technology. In about 10 years, we should be on par with the global leaders and gain a significant share of this high-value market, which is worth hundreds of billions of yuan annually.
