There are different ways boilers are defined. We broadly define boilers as being water-tube or fire-tube. Firetube boilers look like the picture below. They are used for lower pressures (<300 psi) and lower steam purity applications.
boilers are universally used (pressure is above 17 bar and steam generation is more than 7000 kg/hr). In these boilers, water flows inside tubes and drums, and receives heat by radiation and conduction from combustion gases flowing over the tube surface. Water- tube boilers may be classified in several ways: • Straight or bent tube.
The rear box header is connected to the drum by tubes. Longitudinal or cross baffles can be used with either type. Bent Tube. Bent tube boilers usually have three drums. The drums are usually of the same diameter and positioned at different levels with each other.
