An inert carrier gas transports dry, pulverized coal into the gasifier, where it contacts oxygen and steam. Our gasifiers use a membrane wall of high-pressure water/steam tubes and multiple burners to separate the syngas from the slag.

Coal and/or petroleum coke is pulverized and fed into the gasifier along with oxygen that is produced in an on site air separation unit. The combination of heat, pressure, and steam breaks down the feedstock and creates chemical reactions that produce hydrogen .
Three major types of gasification systems are used today: moving bed; fluidized bed; and entrained flow. Pressurized gasification is preferred to avoid large auxiliary power losses for compression of the syngas. Most gasification processes currently in use or planned for IGCC applications are oxygen-blown.
Integrated Gasification Combined Cycle (IGCC) Technologies discusses this innovative power generation technology that combines modern coal gasification technology with both gas turbine and steam turbine power generation, an important emerging technology which has the potential to significantly improve the efficiencies and emissions of coal power plants.

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.
Developments in modelling and simulation of coal gasification 5 Power generators, oil refinery operators and producers of chemicals such as methanol and ammonia have turned in recent years to gasification to unlock the power of coal and other carbon-based fuels.
In this paper, through model experiment of the underground coal gasification, the effects of pure oxygen gasification, oxygen-steam gasification, and moving-point gasification methods on the underground gasification process and gas quality were studied.
Coal-water slurry gasification technology requires coal with better slurry flowing compared to pulverized coal gasification technology, which is more adaptable to a wider range of coals. China has also been developing pulverized coal gasification technology.
