Description:
The gasifier is the main gasification system component. It is a robust pressure vessel where air (or oxygen), water, and a suitable fuel are brought together and heated, stimulating controlled thermal and chemical reactions that yield gaseous process flows made up of synthesis fuel (syngas) products, chiefly carbon monoxide and hydrogen, along with byproducts such as hydrogen sulfide, carbon dioxide, and slag (mineral residues from coal). The syngas stream – and extracted steam flow in combined cycle plants – is used to power turbine/generator sets to produce electricity, while the byproducts may be separated, captured, and stored for reuse or for sale as chemicals.
