COCHRAN BOILER (Spheroid)

This auxiliary boiler has an all welded shell, a seamless spherically shaped furnace and small bore tubes. The advantages of this boiler campared to older design are: 

1. Increased steam output for the same          size, mass and cost of earlier designs.

2. Increased radiant heating surface.

3. Efficient and maintain.

4. Easy to maintain.

5. No furnace brickwork required - apart          from burner quarks.

6. With small tubes, fitted with retarders,        gas velocity and turbulence are                     increased. This gives cleaner tubes             and better heat transfer.
