Syngas

Technical
Despite the similarities between syngas and natural gas, there are differences which impact the design of the combustion turbines they fuel.
Gasification-derived syngas differs from natural gas in terms of calorific value, composition, flammability characteristics, and contaminants.
Natural gas consists mainly of methane (CH4), whereas syngas consists mainly of carbon monoxide (CO) and hydrogen (H2). The H2 composition of the syngas results in a higher flame speed and broader flammability limits, meaning the syngas produces a stable flame at leaner conditions than natural gas and the combustion speed is much quicker than natural gas. This more rapid combustion speed limits the use of conventional natural gas combustor nitrogen oxide (NOx) control. Another complication is the relatively high concentrations of hydrogen sulfide (H2S) in syngas compared to natural gas. [1]
