Aug 23, 2017 · • There are other dangers associated with burning coal, too. CCS technology sends the syngas to a shift reactor, where it encounters steam. That steam transforms the carbon monoxide that's present into hydrogen and even more CO2. The CO2 is then captured from the gas stream, compressed, and dehydrated.
When using coal as the fuel source, one approach to coal firing is the indirect-fired gas turbine cycle. In this cycle, coal combustion gases are passed over tubes that are cooled with clean, high-pressure air; the tubes heat the air to temperatures above 2,000 F (1,093 C), and the hot air is used to drive the gas turbine. Another approach is to gasify the coal and burn the gases that are produced in the gas
