High efficiency electric power generation: The environmental role

“…Lurgi fixed bed gasifiers have a long history and are widely applied for syngas production [24,25]. In their original form brown coal was gasified with oxygen-steam mixtures and the ash was removed in dry form by a rotating grate that also supported the bed.…”

“…13. The BGL slagging gasifier [24]. high heating value, coal ash with favorable melting-viscosity characteristics, and sufficiently high oxygen concentration of the feed stream.…”

Analysis for the Syngas Composition of Gasifier

“…(6) H2S and COS will be equilibrium at designed temperature after shift reaction. (7) Carbon conversion rate can be adjusted to obtain better results. This is different from Watkinson [4] et al, for they chose to fix the carbon conversion while set the temperature to be varied.…”

“…However to assure the suitability the model were first constructed with only pure carbon element in consideration. From the books about coal combustion and gasification, we know that the major chemical equations involved with gasification are: [5][6][7][8][9]…”

Energetic analysis and optimisation of an integrated coal gasification-combined cycle power plant

“…IGCC power plants offer a number of advantages over conventional coal combustion power plants, i.e. [1]: -reduced emission of pollutants; -higher energy conversion efficiency; -ability to accept a variety of coal feedstocks. The most important disadvantage is the low level of experience.…”
