Development of a No-Harm Practical Test to Prevent Side-Effects of Additives in Heating Oil

No-harm criteria ensure that additives do not have any undesirable side effects in addition to their effect. Until now, there has been no application test for this in the heating oil sector. Such a test was developed in the present project to investigate possible interactions of the additives in the application. For this purpose, a circuit test rig is used in which an additivated heating oil is passed through a heated filter under defined conditions. The filter is representative of a real nozzle filter, and a relocation of the filter can be achieved in the test. Operating parameters were developed, with which the target values of a maximum test run time of about 250 h and a small sample quantity could be achieved. Repeatability has not been adequately tested at this time. A complete description of the method is part of this report, as well as some suggestions for improvement.
