摘要
1993年中国煤炭产量已达1.14Bt,约占一次能源消费量的76%。大约80%的煤炭产量为直接燃烧利用,其平均利用效率仅29%,低于世界平均水平。此外煤炭生产过程中排放的矸石、中煤和煤泥数量可观,其中可资热能利用的数量约占30%~40%。为有效利用煤炭和低质煤,本文讨论了提高其利用效率的若干途径,诸如循环流化床燃烧,加压流化床燃烧,热电联产和区域供热,煤气化联合循环发电,先进的煤炭完全气化,大容量发电和型煤。
The output of run-of-mine coal reached 1.14Bts,accounting for 76%in the primary energy production and consumption in 1993 in China. Among which about 80%coal production were bulk burnt. The average utilization efficien-cy is only 29%,which is lower than the average vvorld level. A large amount of low grade coal were discharged from coal production. Among which about 20%~30% low grade coal can be used as fuel. For efficient use of coal and low grade coal, some of the important measures with improvement efficiency,including the circulating fluidized bed combustion,pressurized fluidized bed combustion,heat and power cogeneration/district heating,GCC,advanced total coal gasification,large size power plant and briquette are dis-cussed in this paper.
