Fire Tube Boiler Construction and Working Principle of Fire Tube Boiler. The construction of a water tube boiler can be equipped with cylindrical shell, vertical, firebox in the base, space for water in the center segment, and space for steam in the higher segment. A fire-grate is located at the fire-box base as well as coal is fired-up on the
Radial horizontal tube boilers avoid the flat tubeplate of the Cochran boiler in favour of a circular firebox, a shape that better resists pressure. They thus have their tubes arranged radially, so as to seat more easily by entering the firebox perpendicular to the plate. Robertson boiler [ edit ]
