摘要： An oxy-combustion firing configuration, process, and apparatus can reduce the consumption of oxygen and fuel in an oxy-fuel combustion processes. Processes in accordance with the present invention include operation of an automated logic control device which controls an oscillating valve and controller. The valve and controller are used to oscillate the fuel and/or oxygen supplied to individual burners in a furnace. The oscillating parameters, such as frequency, amplitude, duty cycle, and phase difference between individual burners and their stoichiometry ratio are set to initiate preferable oxy-combustion in that furnace. Selective burner placement in the furnace enables the formation of deflagration zones which can provide very intense heating and complete combustion.

摘要： An oxygen enrichment system is provided which uses the existing air/fuel burners of a regenerative furnace to distribute additional oxygen to the burners for increased efficiency, and reduced nitrous oxide emissions. The centrally positioned cooling air lances in the burners of a regenerative furnace are modified to deliver oxygen when the burners are firing for oxygen enrichment. During the burmer firing cycle, oxygen is delivered from an oxygen supply through the oxygen lance to provide a central oxygen jet. The fuel is delivered concentrically around the oxygen jet. During the non-firing cycle of the burner, cooling air or other cooling fluid is delivered from the cooling air supply through the oxygen jet for cooling the offside of the furnace.

摘要： A heat exchanger useful for preheating oxidizing gases in a combustion process includes a shell having an inlet and an outlet for the ingress and egress of a first heat exchange fluid, such as a flue gas or preheated air. A first tube manifold couples an inlet end-cap to the first end of the shell. The inlet end-cap has an inlet for receiving a second heat exchange fluid, such as an oxidizing gas. In one embodiment, a second manifold couples an outlet end-cap to the second end of the shell. The second manifold includes an outlet tube therein extending from the second manifold through an outlet opening in the outlet end-cap. A tube bundle is disposed within the shell for transporting the oxidizing gas through the heat exchanger and is coupled to the first and second tube manifolds. The outlet tube collects oxidizing gas flowing through the tube bundle for discharge to a combustion system. The outlet end-cap is pressurized with an inert atmosphere and houses a chemical detector to detect the presence of oxidizing gas within the outlet end-cap.

摘要： An oxy-burner having a back-up firing system includes an oxidant conduit coupled to an oxidant injector nozzle. A primary oxygen line is coupled to the oxidant conduit and transports oxygen into the oxidant conduit. An auxiliary air ejector is coupled to the oxidant conduit and is configured to receive a motive fluid and to entrain ambient air and force the entrained air into the oxidant conduit. In operation, upon detecting a disruption in the primary oxygen supply, a motive fluid is supplied to the auxiliary air ejector. The motive fluid injected by the auxiliary air ejector entrains ambient air sufficient to either continue operation of the oxy-burner, or provide cooling air to the oxy-burner in the event that the burner is shut down. Upon restoring the primary oxygen supply, the back-up oxy-burner system can be deactivated and the oxy-burner return to standard operation.

摘要： A self-cooled oxidant-fuel burner consisting novel fuel and oxidant nozzles and three compartment refractory burner block design is proposed. The new oxidant-fuel burner can fire in high-temperature (2200.degree. F. to 3000.degree. F.) and high-particulate (or high process volatiles/condensates) furnaces without over-heating or causing chemical corrosion damage to it's metallic burner nozzle and refractory burner block interior. Using various embodiments of nozzle and block shape, the burner can offer a traditional cylindrical flame or flat flame depending on the heating load requirements. The new features of this burner include unique fuel nozzle design for the streamline mixing of fuel and oxidant streams, a controlled swirl input to the oxidant flow for desired flame characteristics, a controlled expansion of flame envelope in the radial and axial dimensions, and efficient sweeping of burner block interior surface using oxidant to provide convective cooling and prevent any build up of process particulates. In addition, a relatively thick wall metallic nozzle construction with heat conduction fins enable efficient heat dissipation from the nozzle tip and providing a maintenance free burner operation.

摘要： A kiln adapted to recycle kiln dust includes a recycle dust pipe in fluid communication with an oxidant stream to increase the concentration of oxygen in the fluidized recycle dust before the recycle dust stream is directed into the kiln flame. Increasing the oxygen concentration in the recycle dust stream improves the efficiency of the recycling process. A supplemental fuel stream may be introduced into the recycle dust stream to provide an additional flame to preheat the recycle dust stream before the recycle dust stream is directed into the kiln flame.

摘要： Superior heat transfer in a kiln is achieved by the use of at least one injector which injects both an oxidant, preferably containing oxygen, and a secondary fuel into the kiln. The injectors are provided so that the energy resulting from the combustion of the different fuels in the kiln heats specified regions of the kiln, without causing hot spots on the refractory walls. A firing scheme is described for the oxygen and fuels which allows an increase in the amount of heat released toward the load, resulting in significant increases in kiln efficiency and production. Low quality fuels may be used, as well as using and/or recycling more insufflated dust, without an adverse effect on the main flame.
