Disadvantages of shell boilers: The package principle means that approximately 27 000 kg/h is the maximum output of a shell boiler. If more steam is required, then several boilers need to be connected together. The large diameter cylinders used in the construction of shell boilers effectively limit their operating pressure to approximately 27 bar.

design pressure of 160 psig. Boilers for operation over 250 °F or 160 psig must be constructed in accordance with Section I, Power Boilers, of the ASME Boiler and Pressure Vessel Code. Due to limitations of control and safety settings, desired operating temperatures between 240 °F and 250 °F may require the use of a Section I boiler.

tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure obtainable is limited by their large shells to about 300 psi. Fire-tube boilers are used for heating systems.
