How steam engine is cooled when working?

Steam engines are typically cooled using a combination of water and air. The steam produced during operation is condensed back into water in a condenser, where it releases heat and is cooled by circulating water, often drawn from a nearby source. Additionally, in some designs, air is used to cool parts of the engine, particularly in the case of smaller or portable steam engines. This cooling process helps maintain optimal operating temperatures and prevents overheating.
