Thomas Newcomen's steam engine helped spawn the Industrial Revolution. |
|
Before long steam power was applied to drive textile machinery. |
|
The HRSG can be designed with supplementary firing of fuel after the gas turbine in order to increase the quantity or temperature of the steam generated. |
|
The separate condenser did away with the cooling water that had been injected directly into the cylinder, which cooled the cylinder and wasted steam. |

|
The remainder of the stroke is driven by the expansive force of the steam. |
