Thus wet back boilers ensure lesser radiation losses and hence save fuel. The layout of the tubes involves the number of passes the tube will make to pass the heat from the boiler furnace before being discharged. These can be two- pass and three pass boiler. Depending upon the layout of tubes boilers can be two pass or three pass boilers.

Read MoreThe term boiler is applied to the single heat source that can supply either steam or hot water (a boiler is often called a heater). Boilers may be classified according to several kinds of characteristics. They are typically made from cast iron or steel. Their construction design may be sectional, portable, fire-tube, water-tube, or special.
Read MoreWater tube boilers raise steam fast because of large heat transfer area and positive water circulation. Thus they respond faster to fluctuations in demand. Further single tube failure does not lead to catastrophe. Question 415. What Type Of Boiler Does Not Need A Steam Drum ? Answer : Super-critical pressure boiler. Question 416.
Read MoreNaturally, the steam pressure in the boiler acts upon the firebox crown externally, attempting to crush the firebox and also to expel it downwards from the boiler. The effective water level can be altered by the gradient of the line and particular care should be taken when moving an engine from elevated steaming bays that have a steep slope to

Read MoreThe Water-tube boiler consists of the furnace. Water flows through these tubes. Coal and air are burned in the furnace. The heat from the combustion heats the tube as well as the water inside the tube. Remember in the case of a fire tube boiler, the tube doesn't have water, it has hot gases instead of water. Boiler drum
Read MoreA short history of boiler designs Shell and tube-saturated steam boilers of the current packaged form have been manufactured since before the second world war, and their lineage may be traced directly back to the Cornish boilers of the early nineteenth century, invented by the British inventor and mining engineer Richard Trevithick (1771–1833).

Read MoreThen, if direct steam is used instead of a reboiler, the steam can be turned on to flush out the air in the system. This is similar to purging a steam heating system in a house. If direct steam is not being used, water should be fed into the column at the feed point. This water will run down to the reboiler and provide steam.

Read MoreA fire-tube boiler is a type of boiler in which hot gases pass from a fire 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..
