  • Shell Boilers

    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.
