Cochran Boiler: Definition, Parts or Construction, Working

We know this is a fire tube boiler. In the tube, hot flue gases pass and water is surrounded. So the hot flue gases are passing through tubes. The hotness of the fire tube starts heating the surrounded water. The water starts evaporating and at some point it becomes steam. Now the steam comes at the top of the boiler.

What is Locomotive Boiler?- Parts, Working, And Uses

Grate: Just like any other horizontal boiler, Locomotive boiler has a grate that contains the fuel used for combustion. Fire Hole: This hole is at the rear end of this boiler which receives the solid fuel to be ignited into the furnace through the fire hole. Boiler Tubes: These tubes receive the hot flue gasses and as a result, they are able to transfer the heat to the surrounding water.
