Indicative diagram showing the oil temperature at burner pump inlet vs. oil viscosity
Example: if the oil has a 50°E @ 50°C viscosity, the oil temperature at the pump inlet should be 80°C (see diagram).
Indicative diagram showing the oil pressure according to its temperature
Indicative diagram showing the oil atomising temperature according to its viscosity
Example: if the oil has a 50°E @ 50°C viscosity, the oil atomising temperature should be between 145°C and 160°C (see diagram).
