According to Shandong Tianli Drying Equipment Co., Ltd., the brown coal clean combustion technology jointly developed by the Shandong Provincial Academy of Industrial Energy Conservation Center and Shandong Tianli Drying Equipment Co., Ltd. achieved a breakthrough, breaking the technical problem of the low-calorie-valued lignite that has plagued the world's power generation industry. The application of this lignite drying technology can make the processed inferior coal heat level reach the level of standard coal.
According to expert assessment, this technology, called the high-bed superheated steam lignite pre-drying clean coal complete set process, can be upgraded and upgraded through the lignite pretreatment process to increase the lignite energy density and reduce its moisture content. Reduce carbon dioxide emissions and fuel consumption, reduce the loss of power plant supporting systems, and increase power generation efficiency of power plants.
Li Sheng, Shandong Tianli Drying Equipment Co., Ltd. told reporters: “The key factor in solving the lignite burning problem lies in reducing the moisture in the coal, that is, drying the lignite before it is burned. Research shows that if the lignite's moisture is decreased from 37%, For 31%, only a reduction of 6 percentage points will enable the net efficiency of the boiler to increase by 2.6%, the fuel volume to decrease by 10.8%, the smoke volume to decrease by 4%, and the energy saving effect will be very significant.†He explained that as of now, Tianli Drying has The Huaneng Jiutai Power Plant and the Shanghai Electric Power Corporation under the China Power Investment Group have signed a cooperation agreement. Other power groups such as Huadian Group, Guodian Group and Datang Power also plan to implement the technology. The two parties are actively negotiating and the market share of the technology is expected to increase. 5 billion to 6 billion yuan.
Lignite is a resource with high moisture content, high ash content, low calorific value, low ash melting point, heavy pollution, and relatively low utilization rate. At present, China's high-quality coal resources such as bituminous coal and anthracite have been fully utilized, and there is limited space for expansion. The large-scale development and utilization of lignite has only just begun. According to the current remaining economically recoverable reserves and production capacity, Shandong's coal mining can only be maintained for about 20 years, and most of it is brown coal. To this end, Shandong coal companies actively implemented the “going out†strategy. The development of the Yankuang Group has extended to foreign countries. The first phase of the 1.8 million-ton/year coal-to-methanol project of the Erdos Nenghua Company of Yanzhou Coal Mining Company was started in Inner Mongolia a few days ago, marking the beginning of The construction of the Ordos coal-to-electricity base in Yankuang was formally initiated. This is the first coal chemical project invested by Yankuang Group in Erdos, and it will strive to complete and put into production in 2012, and accelerate the preliminary preparations for the 1 million tons/year methanol to olefins and 5 million tons/year coal-to-oil projects.
