Techonologies - Acoustic Liquid Fuel Burners
Introduction
A new design of industrial liquid fuel burner, called
Acoustic Liquid Fuel Burner, has been developed which
would be used in the metallurgical industry where high
pressure air atomised burners with a long flames of
about 8 to 12 meters length for the reheating of liquid
metals in rotary furnaces, etc., and with 4 to 8 metres
length for boilers, having bushy type of geometry are
required. In this new design the acoustic waves are
utilised to atomise the liquid fuels in a more efficient
manner which results several advantages. Presently high
pressure air atomised burners or centrifugal burners
are being used by the metallurgical industries, but
these burners not only having high cost, but also require
high operating and maintenance cost.
The new acoustic burners have been tested In place
of these burners in Hindustan Copper Ltd., Ghatshila
and in Rourkela Steel plant, and found that it can replace
the conventional burners very successfully with a appreciable
percentage of oil saving. Test results at Hindustan
Copper Ltd., Ghatsila, India showed that fuel saving
to the extend of 23% have been achieved.
The major advantages of the burners are : Acoustic burner
requires low air pressure as well as low oil pressure
for atomisation. Due to finer atomisation (Mean particle
size 20 mm. in the cause of fuel oil) better combustion
takes place resulting in reduction in excess air requirement
from 31% to 6% . High flame temperature achieved, boosting
the heat pick up faster by the metal. The fuel saving
upto 23% is achieved. The acoustic burners give the
desirable flame geometry and characteristics as required
by industrial furnaces.
