Cochran Boiler Classification
The Cochran boiler is a specific type of stationary steam boiler. Its design is characterized by its orientation and the path of combustion gases.
Understanding Cochran Boiler Features
- Orientation: The boiler is designed vertically, meaning its main axis is upright.
- Gas Path: It is a fire-tube boiler. This means the hot combustion gases pass through tubes surrounded by water.
- Components: Key parts include a cylindrical shell, a firebox (combustion chamber) inside the shell, a furnace tube, smoke tubes, a smokebox, and a vertical chimney.
Identifying the Correct Type
Based on its structure:
- The vertical orientation is a defining feature.
- The combustion gases travel through tubes (fire tubes) within the water shell.
Therefore, the Cochran boiler fits the description of a vertical fire-tube boiler.
