2019-8-11 · The design of fire-tube boilers consists of a bundle of fire tubes contained in a shell and the evaporating process takes place outside the fire tubes generating steam. Fire-tube boilers are often characterized by their number of passes, referring to the number of times that the
2004-3-19 · 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.
The mechanical design of a shell and tube heat exchanger provides information on items such as shell thickness, flange thickness, etc. These are calculated using a pressure vessel design code such as the Boiler and Pressure Vessel code from ASME (American Society of Mechanical Engineers) and the British Master Pressure Vessel Standard, BS 5500.
