Abstract
锛?/p>
Low-quality coal refers to raw coal or coal-washing products containing high
Impurities like minerals
锛?/p>
Sulfur and moisture etc. Whichever stages or kinds it belongs to
锛?/p>
these
impurities deteriorate
锛?/p>
sometimes even clear its efficiency. Coal donat
es our country鈥檚 energy
systems for 70 percentages of Primary energy consumed. In 2010
锛?/p>
Chinese coal production exceeds
3.2 billion tons and makes up for 45 percentages of the whole global coal production. Nonetheless
锛?/p>
natural Chinese coal is poor with the low-quality coal making up for 40 percentages of the whole coal
reserves. Therefore
锛?/p>
upgrading of this portion has a great strategic significance to sustainable energy
supplement and high economic development since coal donates Chinese energy. Low-quality coal
