Fire-tube boiler - WikipediaBack boilers were popular heating systems in the 1960s, 70s and 80s. They were bulky heating systems fitted behind a gas fire or stove and are no longer made. In terms of ventilation, a back boiler is likely to need much more than a modern condensing boiler.Flued boiler - WikipediaRifled plain smoke tubes Can be equipped with pin tubes on request The special spherical shape of the furnace top plate gives an increased stability against ship vibrations and protects this part of the boiler against partial overheating, because residues in the boiler water are led to the boiler bottom before they can accumulate on the furnace top plate

rifled tubes boilerA fire tube boiler is a type of boiler in which hot gases from a fire passes through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.rifled tubes boilerA simple flue must be long if it is to offer adequate heating area. In a short boiler shell, such as required for a steam locomotive, this may be done by using a U-shaped return flue that bends back on itself.Richard Trevithick had already used a return flue with his first 1802 Pen-y-darren engine and 1803 Coalbrookdale locomotive design.

(PDF) A Numerical Analysis of Heat Transfer …Liming · Internally rifled boiler tubes are used to evaporate water into steam inside boilers of thermal power plants.Because of their internally rifled shape, they are more efficient. The boiling crisis takes place later, thus allowing for greater heat transfer between the pipe and the fluid inside the pipe.Types of Smoke Tube Boiler--ZBGBoiler tubes must be able to endure extremely high temperatures, pressures, and potentially wide fluctuations in demand depending on the application. Boiler re-tubing and tube replacement can extend the life of the boiler, and saves the tubes from deteriorating due to scale build up and cracking.
