Modernize Fuel Trains for Higher Safety, Lower Carbon, and Total Operating Resilience

Many industrial steam facilities in Saudi Arabia rely on legacy Heavy Fuel Oil (HFO) or Diesel fuel systems that suffer from severe pipe fouling, high burner maintenance, and strict environmental emissions penalties under NCEC and SEEC standards. In addition, outdated mechanical fuel trains lack automated safety shutoff interlocks mandated by Saudi Aramco SAES and NFPA 85 codes.

Saudi Boilers Company designs and installs turnkey Fuel Systems Retrofits. From gas pressure reduction and metering stations (PRMS) and double block-and-bleed safety valve trains to pre-heated oil pumping skids and hydrogen-blend co-firing integration, we enable seamlessly automated dual-fuel operation with maximum combustion safety.
