What did the separate condenser do?

The separate condenser, often used in steam engines, improved efficiency by allowing steam to be condensed separately from the engine's working cylinder. This process reduced the amount of heat lost and minimized the need for continuous heating, enabling the engine to operate more efficiently. By maintaining a vacuum in the condenser, the engine could utilize a greater pressure differential, leading to increased power output. Ultimately, it contributed to the overall advancement of steam engine technology during the Industrial Revolution.
