1. Horizontal straight tube boilers (a) Longitudinal drum (b) Cross-drum. 2. Bent tube boilers (a) Two drum (b) Three drum (c) Low head three drum (d) four drum. 3. Cyclone fired boilers Various advantages of water tube boilers are as follows: (i) High pressure of the order of 140 kg/cm2 can be obtained. (ii) Heating surface is large. Therefore Learn More
Horizontal tubular vessel, strong enough to contain high-pressure steam in a harsh working environment; closed at either end by the firebox and tube plate. Usually well filled with water but with space for steam – produced by heat from the firebox and boiler tubes – …Learn More
The water tube boiler diagram is shown below, and these two drums are associated via two tubes such as downcomer and riser. At first, the water is supplied into the steam type drum with the help of a water pump. Whenever the fuel is burned, then hot gases will be generated that are permitted to supply in the shell part of the boiler.Learn More
There are two main goals when performing furnace heat transfer calcula- tions: (1) determining the transfer rate and the heat distribution in each heating surface of the boiler, and (2) solving Learn More
Fire Tube Boiler Construction and Working Principle of Fire Tube Boiler. The construction of a water tube boiler can be equipped with cylindrical shell, vertical, firebox in the base, space for water in the center segment, and space for steam in the higher segment. A fire-grate is located at the fire-box base as well as coal is fired-up on the Learn More
Benson boiler is the high pressure, vertical fire tube boiler. This boiler has no drum and is ~designed to operate at critical pressure of 225 bar. Benson boiler has no drum. So the total weight of the Benson boiler is reduced by 20%, when compared to other boilers. The erection of Benson boiler is easier and quicker. 25. Write about Loeffler Learn More
Water tube boilers raise steam fast because of large heat transfer area and positive water circulation. Thus they respond faster to fluctuations in demand. Further single tube failure does not lead to catastrophe. Question 415. What Type Of Boiler Does Not Need A Steam Drum ? Answer : Super-critical pressure boiler. Question 416.Learn More

A boiler, super heater, and reheat are used with the BWR similar to a coal-fired facility, but operating at lower temperature and pressure. In principle, the PWR reactor can attain higher efficiencies than the BWR, but the extra water circulation loop limits the upper end of the efficiency at about 33%.Learn More
Feb 24, 2012 · The basic working principle of boiler is very very simple and easy to understand. The boiler is essentially a closed vessel inside which water is stored. Again, internal furnace fire tube boiler has also two main categories such as horizontal tubular and vertical tubular fire tube boiler. Cross Drum Water Tube Boiler.Learn More
