 An Overview of Coal based Integrated Gasification Combined Cycle (IGCC) Technology

The integrated gasification combined cycle (IGCC) produces electricity from a solid or liquid fuel. First, the fuel is converted to syngas which is a mixture of hydrogen and carbon monoxide. Second, the syngas is converted to electricity in a combined cycle power block consisting of a gas turbine process and a steam turbine process which includes a heat recovery steam generator (HRSG). The combined cycle technology is similar to the technology used in modern natural gas fired power plants.

Coal based IGCC plants are still not fully commercial. A number of demonstration plants with electric output up to 300 MW have been built in Europe and the US, all with financial support from government. The motivation for pursuing this technology is the potential for better environmental performance at a low marginal cost. This is especially true for mercury removal and CO2 capture. In order to compete with conventional pulverized coal plants under current environmental regulation, the main challenges facing the IGCC technology today are capital cost and availability.

  1. Integrated Gastrification

    that might be the most accidentally poetic phrase i’ve heard all day. Keep it up?

  2. All the frustration and rage boiling within her poured into the choking bodies around her. Savous sighed, closing his eyes and sinking against the rock wall behind him. Lanthan saw her move. Radins mental warning didnt help. She let herself smile, let herself fall into him with relief. She gave him a shy smile. She rubbed her belly. Rhae would work completely through her. Ive never been more proud of you. Eyrhaen bobbed her head, loose hair falling forward over her shoulders. Tykir had a warmer heart than that. She stepped back again. She found her own breath finally, staring up at him. Tykirs cock slid deliciously through her hands, the oils from his skin coating her palms. Her body shuddered uncontrollably as heat ripped apart her spine. She ended up draped over his chest, her cheek resting over his heartbeat. She shrugged, sidestepping to lower herself to the edge of one of two couches. She couldnt help her smile. And Im hardly one to object, given that Im truemated to another. Dont you have magic for that?
