No. 6 fuel oil — Heating Help: The Wall

Mar 31, 2005 · March 2005. Rotary gear positive displacement type pump. #6 fuel oil is very difficult to pump with a centrifugal type pump, because of the viscosity at ambient temperature. You can try heating it up to minimum 150 degrees to reach 1000 ssu maximum viscosity for handling viscous medias with centrifugal pumps. To avoid having to heat it, you can

FUEL OILS (HEATING OIL) - Occupational Exposures in

Fuel oil No. 6, sometimes referred to as 'bunker fuel' or 'bunker C', is a high viscosity oil used mostly as a boiler fuel and in commercial and industrial heating. It requires preheating in storage tanks to permit pumping and additional preheating at the burner to permit atomizing.

Viscosity Control for Marine Fuel Oil

Viscosity control of fuels is essential if correct atomisation and combustion is to take place. Increasing the temperature of a fuel will reduce its viscosity, and vice-versa. As a result of the varying properties of marine fuels, often within one tank, actual viscosity must be continuously measured and then corrected by temperature adjustment

Saybolt Universal Seconds - SSU - viscosity versus temperature for typical fuel oils: TF = TC 9 / 5 + 32. SSU (Saybolt Universal Seconds) = centiStokes (cSt) x 4.55 1) 4 - 5000 SSU is the maximum practical limit for pumping. 150 - 300 SSU is the atomization range fuel oil no. 5 and 6. 1) Note that this equation is correct only for a range of viscosities.

Fuel oil viscosity explained - The need to regulate

The viscosity (resistance to flow) of fuel oil increases as its temperature decreases. The higher the viscosity, SSU number, the more resistant to flow the oil is. The viscosity of typical No. 2 fuel oil increases from 35 SSU at 100°F to 52 SSU at 30°F. (See Figure 1.) An increase in viscosity of this magnitude will increase nozzle flow rate
