  • 4 Different Designs of the Fire Tube Boiler: Which Is Best

    Dec 02, 2016 · As a one-pass boiler design, the combustion products pass through the locomotive boiler once. Depending on the arrangement of the tubes and baffles, some firebox boiler designs may be a three-pass or two-pass. The most common characteristic of the firebox boiler design is a furnace that may be contained partially in the boiler.Learn More

    Sep 18, 2020 · The gases again turn 180 degrees; typically, the third pass has smaller bore tubes but more tubes than the second pass. Three or four pass boilers are the most common. A horizontal boiler with an even number of passes will have the flue connection near the front of the boiler and an odd number of passes has the flue at the back end.Learn More

  • 2. BOILERS - Bureau of Energy Efficiency

    combustion gases pass through the boiler. The combustion chamber is taken, as the first pass after which there may be one, two or three sets of fire-tubes. The most common boiler of this class is a three-pass unit with two sets of fire-tubes and with the exhaust gases exiting through the rear of the boiler. Stoker Fired BoilerLearn More

  • 3 pass firetube boiler design - Industrial Boiler

    Here we discuss the importance of single, double and triple pass cooling. Every shell and tube heat exchanger carries a flow of cooling water through its central tube core. But depending on its design, the water may flow through the unit once, twice or three times, which is done to get the optimum cooling performance for the available volume of Learn More

  • Boiler Systems for Industrial Steam Power Plants | GE

    Our two-pass and tower boilers can reach up to 330 bar/ 650°C /670°C in both single and double reheat configuration. In the two-pass boiler configuration, radiant pendant surfaces are located above the furnace, and convective surfaces are arranged horizontally in the second pass, enabling reduced height of the furnace and simple element Learn More

  • Shell Boilers | Spirax Sarco

    Figures 3.2.1a and 3.2.1b show a typical two-pass boiler configuration. Figure 3.2.1a shows a dry back boiler where the hot gases are reversed by a refractory lined chamber on the outer plating of the boiler. Figure 3.2.1b shows a more efficient method of reversing the hot gases through a wet back boiler …Learn More

    Dec 20, 2009 · Tower Types and Two Pass Boilers. The majority of boiler installations the world over are of the two pass design. However tower-type single pass designs find application in cases where the fuel used is highly erosive in nature. In the case of the once-through type of design, the tower type finds its application widely.Learn More

  • 3-pass cast iron heat exchanger oil boiler - good or bad

    Apr 09, 2015 · If there is plenty of room behind it, I will use the 3 pass boiler because it has a better standby efficiency. I will also go out on a limb and get a lot of angry responses, but I can get the wgo just as clean as the three pass boiler. The difference is usually it is easier to get to the heat exchanger on most three pass boilers.Learn More
