The utilization of lignite with low calorific value has always been a technical problem in the world's power generation industry. Recently, a lignite drying technology developed by the Shandong Academy of Sciences can make the heat of the processed inferior coal reach the level of standard coal. Thermal power industry is known as "10 grams of coal consumption, a generation of technology," saying that the use of the lignite pre-drying clean coal technology, the coal consumption per degree of power generation can be reduced by 10-12 grams, and has excellent energy-saving emission reduction effect.
More than 80% of the electricity generated in China is thermal power, and over 90% of coal-fired power is coal-fired. With the requirement of energy strategic reserves, energy conservation and environmental protection, and the development of a low-carbon economy, the use of high-quality coal resources is no longer permitted on a large scale. 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. The efficient and clean use of lignite has become a major issue to be solved.
The key to solving the problem of lignite utilization is to reduce the moisture in the coal and dry it before it is used. This technology, jointly created by the Provincial Academy of Industrial Energy Conservation Center and Shandong Tianli Drying Equipment Co., Ltd., forms a complete set of process technology and equipment, which is safe, reliable and reaches the international advanced level. It is China's clean coal technology. The new breakthrough, with independent intellectual property rights, has been granted 22 patents, and won the first prize of provincial science and technology progress and the first prize of scientific and technological progress of China Petroleum and Chemical Industry Association.
