Abstract Heavy Fuel Oil is an important resource for power generation in the Middle East. However, the physical and chemical properties of HFO present challenges to the power plant designer and operator. This paper will discuss modern innovations in designs of steam power plants for oil firing, including: • Application of modern supercritical boiler designs to increase efficiency • State of the art NOx and corrosion control to lower environmental impacts • Designs for utilization of heavier oils such as Vacuum Residual Oil (VRO) to increase flexibility • Application of oxy firing to achieve carbon capture. Working in close partnership with Saudi oil/gas producers, electricity producers and university researchers, power plant designers have identified the needs of the oil-fired power generation market to update designs for the fuel and generation challenges of the 21st century. These challenges include the need for highly efficient boiler operation while utilizing lower quality liquid fuels that are increasingly common as refiners extract more of the valuable light fractions. Modern designs must keep emissions of NOx, SOx and particulates low and operate efficiently with those lower quality liquid fuels. This paper will focus on three aspects of modern steam power plant design: 1. Supercritical steam cycles in comparison to subcritical designs including efficiency gains and life-cycle cost savings, 2. Control of NOx and SOx emissions through modern low NOx firing designs, selective catalytic reduction (SCR) where necessary, and additives for SO3 and corrosion control, and 3. The unique challenges in particulate control and fuel handling associated with firing very heavy oils such as Vacuum Residual Oil (VRO). Finally, future options for carbon capture, sequestration and utilization (CCSU) will be briefly discussed.
