Since the beginning of this year, research and investment in the use of lignite have been intensified throughout the country, and lignite use projects have become one of the largest projects.
On June 17th, Guangdong Yijian Investment Co., Ltd. and US COALTEK Coal Technology Company formally signed a technical cooperation agreement at Guangzhou White Swan Hotel. The company plans to invest 200 million U.S. dollars within two years to produce 10 million tons of lignite and a corresponding amount of slime molding products each year. . According to reports, this technology, called low-temperature microwave dehydration and upgrading of lignite, not only converts low-calorie-value lignite into high calorific value clean coal, has a high conversion rate, but also solves the problems of traditional technologies that emit more pollutants and use more water. problem.
In August, the Shandong Provincial Academy of Industrial Energy Saving Center and Shandong Tianli Drying Equipment Co., Ltd. jointly developed a lignite drying technology. The technology, called the high-bed superheated steam lignite pre-drying clean coal complete set technology, can improve the lignite energy density and reduce the moisture content through the technical upgrading of the lignite pretreatment process, which can significantly reduce carbon dioxide emissions and fuel consumption, and reduce the power plant The loss of the supporting system improves the power generation efficiency of the power plant. At present, the promotion of this technology is very smooth. They have signed cooperation agreements with Huaneng Jiutai Power Plant and China Power Investment Group Shanghai Electric Power Co., Ltd., and other power groups such as Huadian Group, Guodian Group and Datang Power also initially reached an agreement.
In October, Yunnan Pioneer Chemical Co., Ltd. brown coal clean coal vaporization utilization test demonstration project, has been approved by the competent department approval, and handle the relevant procedures. This project is a typical demonstration project for comprehensive utilization of low-calorific value brown coal cleansing. It is scheduled to be completed by November 30, 2011 and the product will be released on March 31, 2012. The total investment of the project is 4.525 billion yuan. With brown coal as raw material, it is expected to produce 162.87 million tons of gasoline, 24,130,000 tons of petroleum and natural gas, and 1.9811 trillion cubic meters of liquefied natural gas (compressed natural gas).
It is understood that more than 80% of the electricity generated in China is thermal power generation, and over 90% of thermal power is coal-fired electricity. Lignite is a resource with high moisture content, high ash content, low calorific value, and low ash melting point. Direct combustion of unmodified brown coal raw coal will cause serious environmental pollution problems, and its power generation efficiency is not high, so it has been used less frequently. China's lignite resources account for 13% of the country's coal reserves. In order to achieve the purpose of efficient and clean utilization of lignite, many local lignite utilization technologies have been developed and many lignite mining projects have been invested.
