Regulation 36. Semi-automatic burner system.

(1) For the purposes of this regulation a semi-automatic burner system is one in which the supply

of oil to the burner is regulated by an automatic device within predetermined limits but the burner

is ignited and the plant shut down by hand.

(2) Every semi-automatic burner system fitted to steam boiler shall comply with the provisions

following:

(i) the automatic device shall so regulate the supply of oil to the burner that the pressure

generated in the steam boiler shall not be greater than its authorised safe working

pressure;

(ii) there shall be provided, either as a separate control or incorporated in the automatic

device a mechanism to cut off the supply of oil when the authorised safe working

pressure of the steam boiler is reached or exceeded. Such mechanism shall prevent the

further supply of oil to the burner until it has been re-set manually;

(iii) where there is more than one burner in any combustion chamber the automatic

controls shall operate on all burners;

(iv) means shall be provided to cut off automatically the supply of oil to the burner within a

period of sixty seconds from the failure of the flame thereof. Such means shall indicate

visually that the control is working:

Provided that this provision shall not apply to the oil burning equipment of a steam boiler

installed in a thermal power station operated by an electricity undertaking engaged in the

generation and distribution to the public of electricity energy;

(v) no light-operated flame failure device shall be prevented from functioning by

illumination from any source other than the flame of the burner it controls.
