Advantages of domestic gasification technology and equipment become evident Author/Source: China Chemical Industry News Date: October 10, 2018 Clicks: 89 According to China Chemical New Network, as of 0:18 on September 26, 2018, the entire IGCC (Integrated Gasification Combined Cycle) power generation system at Huaneng Tianjin had been in continuous operation for 3,990 hours (166 days), with the gasification furnace itself operating continuously for 184 days. This breaks the world record of 3,917 hours set by the Mutsu Power Plant in Japan, and the system continues to operate stably, making it the IGCC unit with the longest continuous operation time in the world. This demonstrates that China is at the world’s leading level in terms of green development of coal resources as well as technologies for clean, low-carbon, and efficient utilization of coal. 　　The entire system utilizes the 2000 t/d two-stage dry coal powder gasification technology, which is based on independent intellectual property rights in China and developed by the Clean Energy Technology Research Institute of China Huaneng Group. This technology offers advantages such as good adaptability to different types of coal, high efficiency in producing cold gas, low specific oxygen consumption, and high output per furnace. Since its commissioning, the facility has supplied more than 5.8 billion kWh of green electricity to society. 　　The Huaneng coal-based IGCC power plant project is a key project under China’s 11th Five-Year Plan and the 863 Program, as well as China’s first demonstration project for clean coal power generation. This project utilizes green coal power technology that was independently developed, designed, manufactured, and constructed in China. It mainly consists of gasification, purification, syngas engines, waste heat boilers, and other components. IGCC generates electricity by gasifying and purifying coal before feeding it into a combined cycle; this entirely new method of power generation offers advantages that traditional methods cannot match. Its power generation efficiency can exceed 50%, while pollutant emissions are virtually zero. 　　China began research and development on IGCC technology in the 1980s, going through the **\"Ninth Five-Year Plan\", \"Tenth Five-Year Plan\", \"Eleventh Five-Year Plan\" and the \"863 Program\". It was developed jointly by Huaneng and over 50 other enterprises, and the first IGCC demonstration power plant was put into operation in 2012 – the Huaneng IGCC Demonstration Project located in Tianjin. As the cleanest coal-fired power plant in our country, the dust emission standard for IGCC is ≤0.6 mg/m3 (**the standard requirement is ≤30 mg/m3); the sulfur dioxide emission for IGCC is ≤0.9 mg/m3 (**the standard requirement is ≤100–200 mg/m3). According to the assessment by the Petrochemical Federation, compared with similar foreign technologies, this technology features lower energy consumption and construction costs, reaching an internationally leading level. 　　It is said that this IGCC technology has five advantages. The first is strategic advantage. IGCC**has enhanced China’s international influence in addressing global climate change. The second is the environmental advantage. Although IGCC units burn coal, their pollutant emissions can reach the level of natural gas power plants. Third is the resource advantage. It is of practical significance for addressing China’s energy challenges to effectively alleviate the pressures arising from its resource profile of abundant coal, limited oil, and scarce gas; to improve this technology; and to promote its commercial use. Fourth are the advantages of carbon dioxide capture and cogeneration. In 2016, the world’s largest pre-combustion carbon dioxide capture facility was put into operation at IGCC. Fifthly, IGCC can also be combined with power generation technologies such as hydrogen fuel cells to further improve power generation efficiency.
