    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.Learn More

    British Standards BS 2486 recommends pH 10.5 - 12.0 for shell boilers @ 10 bar, pH 9 could be used in higher pressure boilers only. To condition any suspended matter. This will be a flocculant or coagulant, which will cause the suspended matter to agglomerate and sink to the bottom of the boiler from where it can be blown down.Learn More

  • SHELL AND TUBE HEAT EXCHANGERS

    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.Learn More
