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. Essentially, the coal is not burned directly but undergoes a reaction with oxygen and steam. The latter is achieved by combining the two cycles of firing the coal gas and using the residual heat to produce electricity. The technology contains the following steps. The creates a chemical reaction of the coal with the oxygen.
The syngas is subsequently cleaned and burned with either pure oxygen or air. This creates a superheated steam with which electricity is generated. Coal is transported to the installation where it is pulverized and dried. The pulverized coal is gasified and the ash in the feedstock is recovered as marketable slag. The gas is purified, among others by washing it with water.
This water needs to be cleaned so that it can be re-used. Almost all of the poisonous hydrogen sulphide is removed from the syngas and purified to sulphur. A small part of the sulphur is emitted in to the air. The exhaust gases are cooled and the residual heat used for steam to drive the steam turbine. The electricity production is the output from the gas- and steamturbine.
