  • 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.

  • Blowdown in Boiler

    Blowdown in Boiler Definition. Blowdown in Boiler, Usually, water which is fed to the boiler contains high Total Dissolved Solids (TDS) content as well as other dissolved and undissolved solids in it. On heating water or converting water to steam, these dissolved solids do not evaporate and gets separated from water or steam and settled at the bottom of the shell.
