Characteristics Of Fire Tube Boilers is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
Technical advantages Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.
2019-2-5·The fire tube boilers can achieve flue gas temperatures lower (220 to 250 °C) than water-tube boilers (300 °C) without an economizer, which gives them a slightly better efficiency. However, the former are limited to capacities lower than the latter, for reasons of mechanical strength and safety (with a very large volume of water under pressure).
2019-8-15·A 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. And due to the structural characteristics of the fire tube boiler, the fire tube boiler is generally small in capacity and low in parameters. boiler. There are two types of fire tube boilers produced
Series 200 Fire-tube Boiler. Offers compact design to accommodate specific local code operating limitations. Advances in heat transfer technology provides for greater performance characteristics within our two or three-pass dry and water-backed Scotch Marine configurations.
Boilers - me.ua.edu. 2004-3-19 · There is a tremendous variation in boiler design and In order of increasing capacity, three boiler types are the fire-tube, water-tube and waterwall boilers. ME 416/516 Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made obtainable is limited by their large shells to about 300 psi.
2015-12-17·The repair of a fire tube boiler tends to be more difficult than that of a water tube boiler. Because a fire tube boiler passes hot combustion gasses threw the tubes, it is necessary to use steel or stainless steel tubes. While some water tube boilers may also use steel or stainless steel heat exchangers, often copper tubes are used.
2019-9-27·They are of both fire tube-and water tube type. The greater portion of the heat transfer in such boilers is due to convection. Steam output of waste heat boilers ranges from 3000 kg per hour to 10000 kg per hour. Steam characteristics are 9 bar and 250°C for fire tube boilers and 18 bar and 375°C for multiple forced circulation boilers.
Fire Tube boiler is the simplest form of the internal furnace. Types of Fire Tube Boilers, construction, and working of a Fire Tube boilers. Westinghouse Fire Tube Boiler Westinghouse Westinghouse Fire Tube Boiler the next generation boiler. The Westinghouse Fire Tube Boiler is an exclusively designed high efficiency boiler. Available
Fire tube boiler is a one type of boiler. It is developed as the second of the three major historical types of boilers which are low-pressure tank, fire tube boiler and high-pressure water tube boiler. Sometimes fired tube boiler is called as a smoke tube boiler or shell boiler. A fired tube boiler is
2019-9-10·Most of the early boilers were fire tube boilers. The so-called fire tube boiler is the flue gas generated after fuel combustion flowing through the fire tube or flue pipe, heating the water, steam or steam-water mixture outside the fire tube or flue pipe. There are three types of fire tube boilers, i.e. fire drum boiler, flue tube boilers and
