The first coal gasifier was used by Fontana in 1780 when he directed a flow of water (steam) over red-hot, or incandescent, coal that was partially burned in air. The process can be described using two reactions. Heat was provided by combustion of coal with air, and then the air was replaced with steam to gasify the hot char and produce ...

To sustain fluidization, or suspension of coal particles within the gasifier, coal of small particles sizes (<6 mm) is normally used. Coal enters at the side of the reactor, while steam and oxidant enter near the bottom with enough velocity to fully suspend or fluidize the reactor bed. Due to the thorough mixing within the gasifier, a constant ...

The results showed that syngas components share the same cycles in intermittent coal feed conditions. There is a decrease in H 2 and CO and an increase in tar when the gasifier operates at a lower capacity. The shutdown process took more than 4.4 h and the recovery from a sudden loss of the bed material took more than 2 h.
