Carbon Dioxide Separation from Flue Gases: A Technological

CO 2 is the primary anthropogenic greenhouse gas, accounting for 77% of the human contribution to the greenhouse effect in recent decade (26 to 30 percent of all CO 2 emissions). Main anthropogenic emissions of CO 2 come from the combustion of fossil fuels. CO 2 concentration in flue gases depends on the fuel such as coal (12–15 mol-% CO 2) and natural gas (3-4 mol-% CO 2).

Steam locomotive - Wikipedia

The intense heat causes water in the boiler to turn into steam, which is piped into the cylinders (24). Valves (25) cause the steam to oscillate the pistons (23) back and forth. The piston rod (22), connecting rod (21) and coupling rod (19) transmit the movement to bearings on the wheels, converting the oscillation to rotation, which moves the locomotive as shown in this animation
