Section 3 Fuel oil burning arrangements

3.1.1 Means are to be provided so that, in the event of flame failure, the fuel oil supply to the burner(s) is shut-off automatically, and an alarm is given, see Pt 6, Ch 1, 3.3 Boilers and thermal fluid heaters 3.3.2.

3.1.2 A warning notice is to be fitted in a prominent position at every oil burning unit local manual control station which specifies that burners operated with manual or local overrides in use are only to be ignited after sufficient purging of the furnace and of any additional precautions required when operating in this condition.

3.1.3 For thermal oil heater arrangements, see also Pt 5, Ch 12, 11.4 Thermal oil heater arrangements.

3.2.1 Two or more filters are to be fitted in the fuel oil supply lines to the main and auxiliary engines, and the arrangements are to be such that any filter can be cleaned without interrupting the supply of filtered fuel oil to the engines.

3.3.1 The burner arrangements are to be such that a burner cannot be withdrawn unless the fuel oil supply to that burner is shut-off, and that the oil cannot be turned on unless the burner has been correctly coupled to the supply line.

3.4.1 A quick-closing master valve is to be fitted to the oil supply to each thermal oil heater or boiler manifold, suitably located so that the valve can be readily operated in an emergency, either directly or by means of remote control, having regard to the machinery arrangements and location of controls. A quick-closing master valve is not required to be fitted if the thermal oil heater has a dedicated quick-closing valve fitted to the fuel oil daily service tank to which it is connected providing the heater and tank are in close proximity (see Pt 5, Ch 12, 4.6 Valves on tanks and their control arrangements).

3.5.1 Provision is to be made, by suitable non-return arrangements, to prevent oil from spill systems being returned to the burners when the oil supply to these burners has been shut off.
