INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
FOR "IIP-ENCON" FILM BURNERS
I. SELECTION OF BURNER
IIP ENCON 'Film' Burner are available in four different sizes. Due to its large 'Turn Down Ratio' of 7:1,
these four sizes of burners cover a wide range of application. The burners selection should be done,
keeping in mind the oil firing rate required for the furnace. In a furnace it is better to use more burners
of smaller size (if space permits) than one burner of higher capacity. The different models of burners
and their oil firing rates are as under :
AIR PRESSURE
Burner 500 mm w.g. 600 mm w.g.
Size oil 1/hr. oil 1/hr.
Min. Max. Min.
2A 1 7 2
3A 2 14 3
4A 7 40 9
5A 15 85 17
6A 25 150 30
7A 40 200 45
II. INSTALLATION
The 'Film' Burner is supplied as complete assembly alongwith cast iron mounting plate, refractory block
and burner plate are separate units and are to be properly matched with the burner size. The burner
block and burner plate sizes have been given in figure on the back page.
(a) Installing the burner
The Burner should be mounted on the cast iron burner plate (fitted on the furnace shell) with the help
of four bolts as shown in the diagram.
Ensure that the furnace steel plate has been adequately reinforced from all sides with the help of
M.S. Channels.
The cast iron burner plate has got two holes on each side. Similar holes should be drilled on the
channels welded on to the furnace plate to accommodate the burner plate as shown in the figure.
Ensure that the burner block face is in touch with the cast iron burner plate surface and burner block
is not cracked, while fitting.
Enough care is taken at our end during inspection and while despatching, to avoid any cracking of
burner block. Any minor breakage of corners and chipping of the external surface of the burner block
does not affect the working of the burners.
(b) Air connections
Air pressure has been mentioned in the chart against the burner size. Ensure the correct pressure of
air is available near the burner for getting the desired oil firing rate. For light distilate fuels, such as,
kerosene and light diesel oil, which do not require preheating, air pressure can be decressed by about
100 mm w.g. than what has been mentioned. For furnace oil and other residual fuels, the air pressure
should not be less than 500 mm w.g.
700 mm w.g. 900 mm w.g.
oil 1/hr. oil 1/hr.
