Water Tube boiler and Fire Tube Boiler

Structure of Fire tube boiler vs water tube boiler

Both are shell and tube type of boiler, fire tube have hot gases inside the tube while water tube have water inside the tube and hot gases surrounding them

Steam pressure of water tube boiler vs Fire tube boiler

Steam pressure limit of the fire tube boiler is lies between 20-30 bar and the pressure limit of the water tube boiler is much more than the fire tube boiler and is unlimited within the design limits

Unit output Fire tube boiler and water tube boiler

unit output of the boilers mainly depends on the design limits. Unit output of the fire tube boiler is 20 MW and that of the water tube boiler is unlimited
