Full Text FIELD OF INVENTION
The invention relates to methods., and apparatuses for carrying out combustion for
industrial application. More particularly, the invention relates to a gravity-fed oil-
fired burner capable of carrying out combustion without a fuel oil pressurizing pump.
conTbustion air blower, atomizer tip, and swirelers.
PRIOR ART.
Many industrial applications require large-scale generation of heat from burners.
Various types of burners are available world wide for industrial applications.
Generally oil pumps and blowers/ fans with associated control systems are employed
to pressurize the fuel oil and to supply the combustion air at required parameters.
However there are many applications where there are limitations in employing
blowers and pumps due to various statutory and/ or safety restrictions.
As on today many industrial burners of different capacities are available, all of which
are required to be operated with moderate fuel oil pressures and forced draft
combustion air with precisely machined atomizer tips.
They further require swirlers of calculated geometry and shape and restricted
operational flexibility. Requirement however exists where industrial burners warrant
generation of heat without any or none of the auxiliary equipment such as described
hereinabove. Such requirements may further call for a vertically upward oil firing as
opposed to conventional horizontal firing. Accordingly, there is a need of an oil
burner with the above-mentioned unique features, which the present invention
primarily addresses.
OBJECTS OF THE INVENTION.
An object of the present invention is to provide a gravity fed oil fired burner which
operates"without any externally driven/assisted fuel oil pump.
Another object of the present invention is to provide a gravity fed oil fired burner
which operates without a combustion air blower, and/or without fuel-oil atomizer tip,
wind box.
Yet another object of the present invention is to provide a gravity fed oil fired burner
which operates without any electrical power, both during start up and operation.
A still further object of the present invention is to provide a gravity fed oil-fired
burner which is adaptable to generate a vertically upward firing configuration for
improved combustion.
SUMMARY OF THE INVENTION.
Accordingly there is provided a gravity-fed oil fired burner for generation of heat,
characterized by a burner cup receiving oil from an oil tank disposed at a height
higher than the burner cup ; a first pipe line for delivery of oil to the burner cup via
an oil entry port, an atomizing tube being provided in the burner cup for atomizing
the oil; a second pipe line configured at an opposite end in respect of the first pipe
line , and being flowably connected to the burner cup for supply of an atomizing
medium; at least one first isolation valve to isolate the oil flow followed by .a flow
control valve to control the oil flow rate is disposed on the oil-flow path, and in that a
regulating valye. preceded by a second isolation valve is provided on the flow path
of the atomizing medium, the cup, and the tube arrangements being housed in a
burner pipe
BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWINGS.
Figure-1- shows a block diagram of a gravity-fed oil-fired burner according to the
present invention.
DETAILED DESCRIPTION WITH REFERENCE TO THE DRAWING.
The nature of invention will be clear from the following descripfions with reference
to the accompanying Figure 1.
An oil entry port ( 1) for oil entry is configured on a burner cup (3). Oil is
transported via first a first pipeline (2) to the burner cup(3). At least one first
isolation valve(4) is disposed on the oil delivery path to isolate the oil flow.
A flow control valve (5) to control the required oil flow rate is provided immediately
adjacent to the first isolation valve (4).
The cup (3) is fitted with an atomizing tube(6). An atomizing medium is carried to
the burner through a second pipe line (7). A second isolation valve (8) to isolate the
atomizing medium and a regulating valve (9) to regulate the atomizing medium is
successively disposed on the flow-path of the atomizing medium. The cup (3) and
the tube arrangement (2, 7) are housed in a burner pipe (10).
The level of the fuel oil is maintained to be just above the atomizing tube(6). fhis
level is maintained constantly by setting the opening of the control valve (5). The
opening percentage is governed by the height of a fuel tank ( not shown) and the
design parameters of the first and the second pipelines ( 2, 7).
We Claim:
1. A gravity-fed oil fired burner for generation of heat, comprising a burner cup (3)
receiving oil from an oil tank disposed at a height higher than the burner cup (3);
a first pipe line (2) for delivery of oil to the burner cup (3) via an oil entry port
(1), an atomizingJube_(6) being provided in the burner cup (3) for atomizing the
oil; a second pipe line (7) configured ai an opposite end in respect of the first pipe
line (2), and being flowably connected to the burner cup (3) for supply of an
atomizing medium; characterized in that at least one first isolation valve (4) to
isolate the oil flow followed by a flow control valve (5) to control the oil flow rate
is disposed on the oil-flow path, and in that a regulating valve (9) preceded by a
second isolation valve (8) is provided on the flow path of the atomizing medium,
the cup (3) and the tube arrangements ( 2, 7) being housed in a burner pipe (10).
2. The burner as claimed in claim 1, wherein location of the oil storage tank causes
gravity-feed of oil adequately to the burner cup (3).
3. The burner as claimed claim 1 wherein combustion air is self aspirated
atmospheric air.
4. The burner as claimed in claim 1, wiierein the atomization medium could be
either steam or compressed air.
5. The burner as claimed in claim 1, wherein the level of the oil in the cup is
maintained by a preset flow control valve (5).
6. A gravity-fed oil fired burner for heat as substantially described Hereinabove and illustrated with reference to the
accompanying drawing.
