The IGCC slag did not contain free CaO, and the absence of free lime would address a concern of volumetric expansion during hydration. Automated SEM-EDS analysis revealed that approximately 98% of the IGCC slag particles consisted of calcium-rich aluminosilicate materials.

GTZ CDM Highlights Newsletter, Issue 81, p. 4. Coal gasification technology, often referred to as Integrated Gasification Combined Cycle (IGCC), is the process of gasifying coal to produce electricity. The coal is gasified by burning finely-crushed coal in an environment with less than half the amount of oxygen needed to fully burn the coal.

The Integrated coal Gasification Combined Cycle (IGCC) has received a lot of attention in recent years from the viewpoint of reducing CO2 emissions. IGCC is basically different from conventional pulverized coal-fired thermal power generation systems; electricity is generated by a combined cycle using gas turbines and steam turbines. Thus, it is said …

Gasification in entrained flow reactors is now one of the most dynamically developed technologies of thermal conversion of coal. The basic, solid by-product of this process is slag, and in some cases also fly ash. In Poland, so far there have been no examples of industrial application of coal gasification. However, the high popularity of such systems in …

What is IGCC? THE acronym stands for Integrated Gasification Combined Cycle (IGCC). It is a technology that aims to extract the maximum energy out of a fuel that is burnt. In the case of coal, the carbon conversion efficiency in an IGCC plant is significantly higher than that in a conventional pulverised coal (P.C.) fired power plant.

When there is a step change of + 1% in the inlet oxygen-to-coal ratio, the increase of oxygen-to-coal ratio enhances the combustion reaction and causes faster heat generation and gasification reaction.This leads to a higher gas temperature, as well as a more prominent heat flow to the slag surface. More solid slag melts into the liquid slag …
