Types of Fire Tube Boiler. The different types of this boiler include the following. 1) Cornish Fire Tube Boiler. The first Cornish boiler was approved by an engineer namely “Trevithick a Cornish”. This kind of boiler includes a plane cylindrical shell, as well as a tiny flue pipe holding the heating system, flows through it.
Firetube Boiler Design & Operation. Firetube boilers can handle up to 3000 HP / 450 PSI with a single burner. Though smaller and more compact in design than watertube boilers of similar size, they can take longer to reach operating temperatures from a cold start but can handle steam demand fluctuations well once running.
Jul 02, 2016 · Fire Tube Boiler: In fire tube boiler , the hot gases passes through the tubes and boiler feed water in the shell side is converted into steam. Fire tube boilers are generally used for relatively small steam capacities and low to medium steam pressure.
Aug 21, 2016 · 3. Steam boiler – has similar configuration with the fire-tube boiler but instead of fire, steam or hot water is used in heating the fluid inside the vessel. 4. Flash tankless boiler – it is a special type of water-tube boiler that doesn’t need a storage tank to operate. 5.
Aug 30, 2019 · Types of Fire Tube Boilers 1) Cochran Boiler. It is a vertical, multi-tubular, internally fired, and naturally circulated type boiler. The shell of this type of boiler is arranged in the vertical direction that has multi tubes. These multi tubes arranged in vertical and the high pressurized flue gases will be passed through them.
The most common fire-tube boilers used in facility heating applications are often referred to as ''scotch'' or ''scotch marine'' boilers, as this boiler type was commonly used for marine service because of its compact size (fire-box integral with boiler section). The name "fire-tube" is very descriptive.
Aug 12, 2017 · The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or “ haystack ” boilers, flued boilers with one or two large flues, fire-tube boilers with many small tubes, and high-pressure water-tube boilers.
