• Environmental friendliness

• High thermal efficiency

• Ease of storage and transportation

 Classification according to relative position of water and hot gases.

• Internally fired and externally fired boilers

• • Stationary, portable, and marine boilers

• Fire tube and water tube boilers

• • Single-tube and multi-tube boilers

It is a large sized boiler and cannot be easily transported in different place. It is generally used to produce high pressure steam in power generation industries.

• Cochran Boiler

• Locomotive Boiler

• Lancashire Boiler

• Babcock and Wilcox Boiler

Cochran boiler is a stationary, fire tube, internally fired, horizontal, and natural circulated boiler.

• TRUE

• FALSE

• MAYBE

In here, hot flue gases are present inside the tubes and water surrounds them.

It indicates the steam pressure in the boiler. It is mounted usually on the front top of the steam boiler.

It is a safety device used to prevent the level of water from going down below a critical point, thus avoiding overheating.
