3.3 Control<\/strong><\/h2>\n

The Electric Control Panel supervises burner firing sequence, feed pump duty\/standby switching, and monitors safety interlocks (flame failure, low water level, high steam pressure) across both sides of the process.<\/p>\n

4. Feed Water Treatment Chain \u2014 Purpose of Each Stage<\/strong><\/h1>\n
    \n
  • Water Softener: removes hardness-forming ions to prevent scale build-up on fire-tube surfaces, which reduces heat transfer and risks tube overheating\/failure.<\/li>\n
  • Water Tank: provides buffer storage and residence time ahead of deaeration.<\/li>\n
  • Deaerator: removes dissolved oxygen and CO2 \u2014 the leading cause of pitting corrosion in boiler shells, tubes, and condensate\/feed piping.<\/li>\n
  • Chemical Dosing Barrel: maintains correct alkalinity, scavenges residual oxygen, and conditions sludge\/TDS for controlled blowdown.<\/li>\n
  • Feed Pump: delivers conditioned water into the pressurised boiler shell; run in duty\/standby configuration for continuity.<\/li>\n<\/ul>\n

    5. Water Quality Parameters (EN Standard Reference)<\/strong><\/h1>\n

    Indicative feed-water and boiler-water limits for a low\/medium-pressure fire-tube boiler (below 20 bar). Actual limits should be confirmed against the boiler OEM’s water quality specification and RSC\/CKDL 2020 framework requirements.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n

    7. Commissioning & Inspection Checklist<\/strong><\/h1>\n
      \n
    • Verify safety valve set pressure and test lift\/reseat before first firing.<\/li>\n
    • Confirm low-water cut-off and flame-failure interlocks trip correctly (simulated test).<\/li>\n
    • Check economizer and feed line for leak-tightness under hydro test pressure.<\/li>\n
    • Verify water softener regeneration cycle and confirm treated water hardness < 1 ppm.<\/li>\n
    • Confirm deaerator vent steam flow and dissolved oxygen at outlet meets target.<\/li>\n
    • Log chemical dosing rates against first-week boiler water TDS\/alkalinity trend.<\/li>\n
    • Confirm fire-fighting equipment, room ventilation, and emergency exits are in place before occupancy\/use.<\/li>\n
    • Record burner combustion efficiency test (O2\/CO in flue gas) and file with commissioning report.<\/li>\n<\/ul>\n
