Online (in-process) Dry Chemical Cleaning of Furnaces, Heat Recovery Systems, Air Pre-heaters, Boilers

Online (in-process) dry chemical cleaning of heater and boiler tubes (external fire-side of the tube), through non-hazmat SENTROMAXTM dry chemicals, for both radiant and convection sections in furnaces, as well as furnace, superheater and economizer in boilers.

    •  Conducted “on-the-run” during normal operating conditions with no loss of production
    • Flexible scheduling for the cleaning – limited equipment access required
    • Immediate measurable results and benefits – visible operational improvements while undergoing cleaning process:
    • ✔  Stack temperature reduced
    • ✔  Fuel consumption reduced
    • ✔  Production rate increased

 No damage to tubes, refractory, or instrumentation

    • No negative impact on SCR or other NOx reduction systems  
    • Mechanical and chemical cleaning occur simultaneously, as compared to dry ice or walnut blasting that act mechanically and are low effective methods
    • Little or no scaffolding is required – typical access from existing platforms
    • No cleanup required – non-hazmat SENTROMAXTM chemical decomposes into gas and exits heater in flue gas
    • Green Solution – No negative environmental impact
    • No confined space entry
    • Significantly increased accuracy of IR thermographic readings of tubes skin temperature  

All SENTRO’s cleaning and inspection systems are the result of practical applications combined with continuous research and development.
