3. Exploring the Components of a Steamer’s Steam Engine
The Basics: How a Steamer’s Steam Engine Works
A steamer’s steam engine is composed of several key components that work together to convert heat energy into mechanical energy. The boiler is where water is heated to produce steam, which then flows into the cylinder through a valve called a throttle valve. Within the cylinder, the steam pushes against a piston, causing it to move back and forth. This reciprocating motion is transferred to a crankshaft, which converts it into rotary motion. The rotary motion is then used to turn the ship’s propeller, propelling the steamer forward.
Key Components of a Steamer’s Steam Engine
1. Boiler: The boiler is where water is heated to produce steam.
2. Throttle Valve: The throttle valve controls the flow of steam into the cylinder.
