Currently, China's installed power generation capacity has exceeded 300 million kW, of which thermal power accounts for about 75%, or about 240 million kW, as shown in Table 1. [ALIGN=CENTER] Table 1 Installed Capacity by Region (Unit: 10,000 kW) [/ALIGN] However, for a long time, China's power industry has had high energy consumption, with a plant power consumption rate of about 6.8%, especially in the thermal power industry, where the plant power consumption rate has remained at around 8%, reaching 19.2 million kW nationwide. According to statistics, the standard coal consumption for power generation in China's thermal power plants is 410 g/kWh, which is 80-90 g/kWh higher than that of advanced countries, or about 25% higher. Water consumption is also higher than that of foreign countries. Generally, thermal power plants with secondary circulating water consume 1 m³/s of water per million kilowatts, while advanced countries only consume 0.6-0.7 m³/s, or about 50% higher, as shown in Tables 2 and 3. [ALIGN=CENTER] Table 2 Major Technical and Economic Indicators of China's Power Industry [/ALIGN] [ALIGN=CENTER] Table 3 Comparison of Coal and Water Consumption in Chinese and Foreign Thermal Power Plants [/ALIGN] In China's power infrastructure, large-capacity, high-parameter thermal power units account for a very small proportion. On the other hand, due to various reasons, the main auxiliary equipment in thermal power plants, such as coal mills, circulating water pumps, boiler feed pumps, and boiler forced and induced draft fans, are often oversized. Generally, thermal power units require load regulation during operation, and the corresponding air volume of fans and the flow rate of water pumps must also be adjusted. The traditional method of adjustment is to adjust the opening of dampers or valves, which is extremely uneconomical. Therefore, China's thermal power industry has a high plant power consumption rate. [ALIGN=CENTER] Table 4 Comparison of Plant Power Consumption Rate in China's Thermal Power Plants [/ALIGN] The auxiliary equipment in thermal power plants includes: coal mills, circulating water pumps, boiler feed pumps, and boiler forced and induced draft fans, as well as other electrical equipment. As shown in Table 5, the four major auxiliary machines account for approximately 75% of the plant's electricity consumption, totaling 14.4 million kW nationwide. Of this, furnace draft fans account for about 25%, totaling 4.8 million kW nationwide; circulating water pumps and feedwater pumps account for about 40%, totaling 7.68 million kW nationwide. This means that China's thermal power industry has approximately 12.5 million kW of fans and pumps. [ALIGN=CENTER] Table 5 Proportion of Auxiliary Machines in Thermal Power Plant Electricity Consumption [/ALIGN] In summary, using speed regulation to adjust air volume and flow rate for fans and pumps is the most economical method, and AC variable frequency speed regulation is currently the most efficient and high-performance speed regulation technology. Operational data from units that have completed technical upgrades show that the electricity saving rate for thermal power plant fans and pumps using AC variable frequency speed regulation technology can reach 30-50%, demonstrating significant benefits. Therefore, it is evident that the market potential for adopting variable frequency speed regulation technology in China's thermal power industry is enormous. Because the auxiliary equipment of my country's thermal power plants generally operates at 6KV and has a relatively large capacity, high-voltage, high-capacity frequency converters are required. If the price of frequency converters is calculated at 1500 yuan/kW, the potential market nationwide is approximately 21.6 billion yuan. Even considering only the fan section, which offers the best energy-saving effect and is easy to retrofit, it represents 7.2 billion yuan. Currently, my country's installed capacity is increasing at a rate of 5 million kW per year, meaning the potential market for frequency converters in the thermal power industry is approximately 330 million yuan annually, with the fan section, most likely to adopt frequency conversion speed regulation, accounting for about 1.1 billion yuan. In addition, many gas turbine units in China also require retrofitting their intake fans using AC frequency conversion speed regulation technology to improve production efficiency. Furthermore, the emerging urban "waste-to-energy" industry is gaining momentum. Following Shenzhen and Zhuhai, Ningbo and Nanhai waste-to-energy plants have successively commenced operation. For example, the Nanhai waste-to-energy plant has an installed capacity of 6000 kW, with approximately 1200 kW of various fans and pumps using frequency converters. Data shows that large and medium-sized cities in my country produce 100 million tons of garbage annually, the vast majority of which is untreated and piled up in the suburbs, with a total garbage stockpile exceeding 6 billion tons, occupying 500 million square meters of land. Harmful and toxic substances from this garbage seep into the ground and rivers, causing serious damage to cities. The harmless treatment of urban waste is now urgently needed. There are more than 670 large and medium-sized cities in China. If each city were to build a waste-to-energy plant, it would require approximately 800,000 kW of frequency converters. At a price of RMB 600 per kW, the potential market is approximately RMB 480 million.
