Occasionally a collaboration of water and fire tube boilers is applied to match exceptional demands. From explanation above comparison between Water Tube vs Fire Tube Boiler can be known
In the modern water-tube boiler, separation of the steam-water mixture entering a relatively small steam drum is a complex process. For every pound of steam generated, as many as 15-20 lb of water may circulate through a drum. As a result, 99.97% or more of the circulating water must be removed from steam to ensure the desired steam purity.
In earlier days, the basic fire-tube boiler was manufactured at the factory, and the refractory, insulation, boiler fittings, controls and firing equipment were installed by others. The modern fire-tube boiler is marketed as a packaged unit, and now the majority of fire-tube boilers are packaged type fire-tube boiler.
Jul 27, 2016 · In fire tube boiler the fire or hot gas are present inside the tubes and water surrounds these fire tubes. Since fire is inside the tubes and hence it is named as fire tube boiler. The heat from the hot gases is conducted through the walls of the tube to the water.
What’s the Difference Between Combi and Heat Boilers? Some people are often confused on the difference between a combi and heat boiler. This is mainly because people believe that all boilers are the same, as in they serve the same function of heating water.
Once-through boilers are generally associated with high pressure operation and the feed water enters at high sub-critical (>180 bar) or supercritical pressure whilst superheated steam leaves at a pressure some 20–30 bar lower. Sliding pressure operation is adopted to accommodate requirements of part-load running.

Key Difference – Subcritical vs Supercritical Boiler. Boilers are closed vessels in which a fluid is heated, most of the times, it is water. Even though the name of this is a boiler, the fluid does not necessarily boil in this.
In the once through boiler, many times the load change response is dictated by the firing system and its controls rather than the boiler, per-say. Once through boilers of super-critical pressure boilers have higher efficiency. However in the sub-critical range there is no difference in efficiency when compared to the drum type design.
Mar 19, 2016 · The main difference between fire tube and water tube is that in fire tube boiler the flue gases flow in the tubes and water flows from the shell and in water tube boiler, water flows from the tubes and the flue gases from the shell or passes over the tubes. This is the key difference between these boilers.
Difference Between Industrial Fire Tube Boiler and The fire tube boiler is a kind of industrial boiler that the flue gas generated after fuel combustion flows through the fire drum or flue pipe to heat the water, steam or steam-water mixture outside the fire drum or flue pipe.

Oct 01, 2013 · These methods include natural circulation (Figures 1, 2a–2c), forced circulation (Figure 3a), and a once-through design. Figures 3b, 4 and 5 show examples of a waste-heat water tube and fire-tube boilers with external downcomers and risers.
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.
Jul 02, 2016 · Comparison between Fire tube and Water tube boilers A boiler is a device used to generate s team at a desired pressure and tem pe rature by transferring heat energy produced by burning fu el to water to change it to steam.
Jul 27, 2016 · According to the contents in the tubes, the boilers can be classified as fire tube boiler and water tube boiler. (i) Fire Tube Boiler: In fire tube boiler the fire or hot gas are present inside the tubes and water surrounds these fire tubes. Since fire is inside the tubes and hence it is named as fire tube boiler.
The difference between fire tube boiler, water tube The difference between fire tube boiler, water tube boiler and circulating fluidized bed boiler 2019-08-07 Fire tube boiler is the flue gas generated after the combustion of the fuel flows through the fire tube or the smoke tube, and heats the mixture of water, steam or steam and water outside the fire tube or the smoke tube.

Fire tube boilers. In a fire tube or shell boiler, the hot combustion gases produced by the burner are passed through small tubes arranged in a pressurised cylindrical drum and surrounded by water. Heat energy is transferred to the water which is heated up until it becomes steam.
Fire Tube Boilers are usually used at small steam capacities and low to moderate pressures, that is due to the characteristics of the Fire Tube Boiler itself, which is characterized by producing low steam and pressure capacities. Fire Tube Boilers must reach a certain steam speed to be able to meet the standard pressure of 18kg / cm2. This type

Dec 07, 2016 · Water Tube Boilers. Unlike fire tube boiler, where the hot gas is circulated through tubes to heat water in a tank, water tube boilers involve running water through tubes surrounded by a heated tank. These types of boiler are generally considered safer than fire tube designs and typically require less frequent maintenance.
Jan 22, 2009 · The separated water recirculated to the boiler to make the trip again. Drum boilers are also called sub-critical boilers because they have to operate below the critical point of water to make sure there is a density difference between the steam and water, allowing for separation.
