PART II - STEAM BOILERS

---------------------------------------------------------------------------

Regulation 37. Fully automatic burner system.

(1) For the purposes of this regulation a fully automatic burner system is one in which, while the

electricity supply is switched on, an electrically operated burner starts up, continues in operation

at a preset oil consumption or by flame modulation until the heat demand is satisfied, and then

shuts down.

(2) Energy fully automatic burner system fitted to a steam boiler shall comply with the provisions

following:

(i) means shall be provided to ignite the oil immediately it enters the combustion

chamber;

(ii) an automatic device shall be provided to cut off the supply of oil to the burner within a

period of sixty seconds of the oil entering the combustion chamber if it fails to ignite and

to prevent resumption of the supply until the device is re-set manually;

(iii) means shall be provided to cut off the supply of oil to the burner whenever it is idle or

stopped for any cause whatever;

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

period of thirty seconds from any failure of the flame thereof:

Provide 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 electrical 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;

(vi) the automatic devices shall be coupled either electrically or mechanically or both so

that-

(a) the burner will not start until the draught is established;

(b) the means of ignition is established before the oil leaves the burner;

(c) normal operation is maintained when the flame is satisfactorily established;

(d) the supply of oil to the burner is cut off if the flame is not established

satisfactorily or in the event of any defect in the flame failure device;

(e) there is a time lag of not less than two minutes between the shutting down

and starting up of any burner after an interruption of normal operation; and

(f) failure of the electric supply shall not prevent any of the devices from shutting

down the burners.
