  • Life cycle energy efficiency evaluation for coal

    2019-7-15 · The energy efficiency in coal chemical processing is the weighted average of the twelve main products, and the calculation formula is: (9) η U 3 = ∑ i = 1 12 η U 3 i × α i where α i is the proportion of coal consumption that each coal chemical product consumed (%) and η U 3 i is the energy efficiency of coal chemical product i (%).

  • Coal Processing and Use for Power Generation

    2014-1-1 · Coal processing and clean coal technologies (CCTs) offer important prospects for coal to be used for power generation more efficiently and to provide fewer emissions during energy production. However, CO 2 generation during coal combustion will always accompany the use of coal for power generation. Likewise, there will always be a need for post-combustion cleanup of the emissions from coal

  • Theoretical analysis of schemes for complex coal

    1997-11-1 · To obtain high exergy efficiencies in coal processing yielding heat, it would be proper to burn the raw coal and transfer the produced heat to the consumer. However, the suggested scheme assumes a complex coal processing that allows it to produce other products, e.g., methanol. The letter demands a simultaneous CO and H2 production in gasification.

  • Thermal efficiency of advanced integrated coal

    2017-9-1 · The efficiency penalty of the CO 2 capturing unit was approximately 5.7% and 12.5% in CGDU and 6.9% and 14.0% in HGDU when the CO 2 capturing ratio was 80% and 90%, respectively. 2. The net thermal efficiency can be increased to 54.7–57.2% by improving cold gas efficiency from 80.1 to 85.0% without CO 2 capturing. The values are higher than other reported values.
