Page 10: Oil Grades
In the case of a standstill in which the oil can be expected to change structure, for example aging or phase transitions due to temperature and storage, the burner must be flushed with fuel oil after the standstill. This procedure ensures a good start after standstill. Altered structure of the oil can give rise to altered viscosity, pumpabilty and ignitability. This can cause the pump, valves and nozzles to get blocked. Bentone... -
