    • Aerodynamic study of combustor using axial swirler 

      Mohammad Nazri, Jaafar; M. K. F., M. Nor; Mohamad Shaiful Ashrul, Ishak (Praise Worthy Prize S.r.l., 2011-01)
      A study has been conducted to investigate the flow pattern in a gas turbine combustion chamber by simulation and experimental approaches. Flow pattern inside a combustor is important to self sustain the flame, increase ...

    • Catalytic combustion system for use in Malaysia small gas turbine: A feasibility study 

      M. N. M., Jaafar; A. H., Hussain; Mohamad Shaiful Ashrul, Ishak (Praise Worthy Prize S.r.l., 2011-01)
      Nowadays, the rates of air pollutant produced by small gas turbine in manufacturing and automobile industries increased continuously. Besides that, the uncontrolled rate of emissions released into the ambient air could ...

    • Development of gas turbine spray test rig for biofuel 

      N. N., Raupeeh; M. N. M., Jaafar; M. A. A., Arizal; Mohamad Shaiful Ashrul, Ishak (Praise Worthy Prize S.r.l., 2011-01)
      The design of the fuel supply system to be used for biofuel is one of the systems that are complicated to design. As this system involves a lot of components, all the components in this design play an important role to ...

    • The effect of radial swirl generator on reducing emissions from bio-fuel burner system 

      Mohamad Shaiful Ashrul, Ishak; Mohammad Nazri, Mohd Jaafar; A. Eldrainy, Yehia (Canadian Center of Science and Education, 2009-06)
      A liquid bio-fuel burner system with various radial air swirlers attached to combustion chamber of 280 mm inside diameter and 1000 mm length has been investigated. All tests were conducted using crude palm oil as fuel. A ...

    • Investigation of oil burner combustion performance when utilizing palm biodiesel blends 

      Muhammad Azreen Azeem, Hasagaya; Mohammad Nazri, Mohd Jaafar; Mohamad Shaiful Ashrul, Ishak (Praise Worthy Prize S.r.l, 2011)
      Due to renewability, high production rate, technical feasibility and role in reducing greenhouse gases (GHG) emission, palm oil is in the right position to supply the energy needs by the incorporation into the diesel supply. ...

    • The reduction of noxious emissions using urea based on Selective Non-Catalytic Reduction in small scale bio fuel combustion system 

      Mohamad Shaiful Ashrul, Ishak; Mohammad Nazri, Mohd. Jaafar (Canadian Center of Science and Education, 2011-04-02)
      Selective Non-Catalytic Reduction (SNCR) of oxides of nitrogen (NOx) was studied experimentally by injecting different concentrations of aqueous urea solution in a pilot-scale Bio-fuel fired tunnel furnace at 3-4 % ...

    • Removal of NOx and CO from a Burner system 

      Jaafar, M. N. M.; Mohamad Shaiful Ashrul, Ishak; Saharin, C. (American Chemical Society, 2010-04-15)
      This paper presents the development of an emissions-controlling technique for oil burners aimed especially to reduce oxides of nitrogen (NOx). Another emission of interest is carbon monoxide (CO). In this research, a ...

    • Spray characteristic of palm biofuel blends 

      Ing, N. L.; Jaafar, M. N. M.; Mohamad Shaiful Ashrul, Ishak; Arizal, M. A. A. (Universiti Malaya, 2010)
      The present numerical study on spray characteristic of biofuels, which is the blend of Refined, Bleached and Deodorized Palm olein (RBDPO) and Commercial Diesel Fuel (CDF) in gas turbine, is important. This type of study ...
