Abstract
A line burner assembly is provided for burning a mixture including at least a gaseous fuel and process air to produce a flame. The assembly includes a mixing region which contains an air/fuel mixture. Gaseous fuel and process air are supplied to the mixing region. Combustion air containing oxygen may also be supplied manually or automatically to the mixing region to compensate for a decline in the oxygen level in the process air below a predetermined minimum level to enhance the combustibility of the air/fuel mixture in the mixing region.
Claims39
An assembly for burning a mixture including at least a gaseous fuel and process air to produce a flame, the assembly comprising
- a line burner including a burner base formed to include gas conduit means and air conduit means and means for providing a mixing region,
- means for supplying a gaseous fuel to the mixing region through said gas conduit means provided in the burner base,
- means for introducing process air containing oxygen and inerts into the mixing region to mix with the gaseous fuel in the mixing region to produce a mixture, and
- means for compensating for a decline in the oxygen level in the process air below a predetermined minimum level by introducing combustion air into the mixing region through said combustion air conduit means provided in the burner base to supplement the process air in the mixing region and increasing the oxygen level of the mixture above a threshold level to enhance the combustibility of the mixture in the mixing region, thereby supporting the flame produced therein.
An assembly for burning a mixture including at least a gaseous fuel and process air to produce a flame, the assembly comprising
- a line burner including a burner base formed to include gas conduit means and air conduit means and means for providing a mixing region,
- means for supplying a gaseous fuel to the mixing region through said gas conduit means provided in the burner base,
- means for introducing process air into the mixing region to mix with the gaseous fuel in the mixing region to produce a mixture,
- means for adding combustion air into the mixing region through said combustion air conduit means provided in the burner base to increase the level of oxygen extant in the mixture, and
- means for activating the adding means in response to a decline in the oxygen level of the process air introduced into the mixing region by the introducing means below a predetermined level so that the level of oxygen in the mixture is increased to enhance the combustibility of the mixture in the mixing region to support the flame produced therein.
A line burner assembly for burning a mixture including at least a gaseous fuel and process air to produce a flame, the assembly comprising
- a gas manifold,
- a combustion air manifold,
- a burner base including at least one first aperture in communication with the gas manifold and at least one second aperture in communication with the combustion air manifold, and
- a pair of mixing plates situated on opposite sides of the burner base to define a mixing region therebetween, the mixing plates being formed to include a plurality of apertures therein.
A line burner assembly for burning a mixture including at least a gaseous fuel and process air to produce a flame, the assembly comprising
- a gas manifold,
- a combustion air manifold,
- a burner base including at least one first aperture in communication with the gas manifold and at least one second aperture in communication with the combustion air manifold.
- a pair of mixing plates situated on opposite sides of the burner base to define a burner trough therebetween, the mixing plates being formed to include a plurality of apertures therein,
- means for supplying gas to the gas manifold so that gas passes through the at least one first aperture in the burner base and into the burner trough,
- means for supplying process air to an area surrounding the mixing plates so that process air passes through the apertures formed in the mixing plates and into the burner trough to mix with the gas,
- means for supplying combustion air to the combustion air manifold so that primary air passes through the at least one second aperture in the burner base and into the burner trough to mix with the gas, and
- control means for varying the amount of combustion air supplied to the combustion air manifold by the combustion air supply means in response to a predetermined condition of the process air.
An assembly for burning a mixture including at least a gaseous fuel and process air to produce a flame, the assembly comprising
- a line burner including a burner base formed to include gas conduit means and air conduit means and means for providing a mixing region,
- means for supplying a gaseous fuel to the mixing region through said gas conduit means provided in the burner base,
- means for introducing process air containing oxygen and inerts into the mixing region to mix with the gaseous fuel in the mixing region to produce a mixture,
- means for supplying combustion air to the mixing region through said air conduit means provided in the burner base, and
- means for varying the level of combustion air supplied to the mixing region by the supplying means during operation of the assembly to compensate for a decline in the oxygen level in the process air below a predetermined minimum level to enhance the combustibility of the mixture in the mixing region, thereby supporting the flame produced therein.
A method for controlling the mixture of process air and combustion air with a gaseous fuel in a line burner having a gas manifold, a combustion air manifold, a burner base including at least one first aperture in communication with the gas manifold and at least one second aperture in communication with the primary air manifold, and a pair of mixing plates situated on opposite sides of the burner base to define a burner trough therebetween, the mixing plates being formed to include a plurality of apertures therein, the method comprising the steps of
- supplying gas to the gas manifold so that gas enters the burner trough through the at least one first aperture of the burner base,
- supplying process air containing oxygen and inerts to an area around the mixing plates so that the process air passes through the apertures formed in the mixing plates and into the burner trough, the process air mixing with the gas to provide a combustible mixture within the burner trough, and
- selectively supplying combustion primary air manifold so that combustion air enters the burner trough through the at least one second aperture in the burner base in response to the oxygen level of the process air falling below a predetermined level.
