A steam boiler is a power generation device, used for generating steam by applying the heat energy to water. The pressure range of earlier boilers ranges from low pressure to medium pressure (7 kPa to 2000 kPa/ 1psi to 290 psi).
Classification of boilers. In the water tube boilers, the water is inside the tubes and hot gases surround them. Stirling, Yarrow boiler etc. The boiler is known as externally fired if the fire is outside the shell. Examples: Babcock and Wilcox boiler,Stirling boiler etc. In case of internally fired boilers,
Fire Tube Boilers. Also referred to as smoke tube boilers, shell boilers, package boilers Multiple gas paths - 2, 3 and 4 pass Internal furnace or fire box as the 1st pass Dry back or wet back design Single fuel or dual fuel design Little or no steam separation equipment.
