A fire-tube boiler is a type of boiler in which hot gases from a fire pass through one or more tubes running through a sealed container of water.
Boiler operators and technicians should pay close attention to three key safety devices to protect personnel, equipment, and the facility: Safety valves. The safety valve is the most important safety device in a boiler or domestic hot-water system.
How to detect fire side corrosion: When the surface of the boiler tubes are exposed to combustion gases, the damaged area of the surface will change color. Long-term corrosion of this type affects
As the water and steam both are in same vessel a fire tube boiler cannot produce steam at very high pressure. Generally it can produce maximum 17.5 kg/cm 2 and with a capacity of 9 Metric Ton of steam per hour. Types of Fire Tube Boiler. There are different types of fire tube boiler likewise, external furnace and internal furnace fire tube boiler.
Name several factors that should be considered in locating a central boiler plant for a large building. Central boiler plants should be located to minimize expense to route chimneys, should be close to loads to minimize piping expense, have good access for fuel supply, and combustion air.
Fire tube boiler- the fire/heat goes through the inside of the tube in eather a vertical boiler or a horizontal boiler. Water tube boiler- the fire/heat goes around the outside of the tubes with water inside the tubes. Tubes will be attached to a steam drum on top and a mud drum at the bottom of the boiler. will have some pics later. Dave
