摘要： An oxygen enriched boiler having a burner subassembly and a steam subassembly is disclosed. The burner subassembly has a fuel inlet, an oxidant inlet, a combustion chamber, a flue gas composition detector and a flue gas outlet. The fuel inlet provides fuel to the combustion chamber, the oxidant inlet provides an oxygen-enriched inlet stream to the combustion chamber, the combustion chamber burns the fuel and the flue gas composition detector measures at least one characteristic of the flue gas. The steam subassembly has a supply water inlet, a heat exchange zone, a water drum, a steam quality actuator and a steam outlet. The supply water inlet provides feed water to the heat exchange zone, the heat exchange zone transfers heat generated by combustion of the fuel to the water to generate steam, the water drum receives the heated water and steam from the heat transfer zone and maintains the water and steam at a selected steam pressure and water level, and the steam quality actuator regulates at least one characteristic of the steam. Flue gas characteristics, as well as other boiler performance variables, are monitored. At least one controller actuates on the oxidant injections to control combustion. The controller calculates the optimum oxidant distribution in real-time for a series of injection points to minimize undesired flue gas emissions while maintaining the desired steam conditions and boiler operating conditions.

摘要： An injection lance for injecting a fluid over a predefined target area within a system includes a support block with an inlet side and an outlet side. A plurality of channels are disposed non-parallel with respect to each other within the support block and extend between the inlet and outlet sides of the support block so as to receive fluid at the inlet side and deliver fluid through the support block for injection from the outlet side of the support block over the target area. At least two channels extend from the inlet side toward the outlet side in a direction away from a central axis of the support block, where the central axis intersects the outlet side. The target area includes a plurality of consecutively aligned sectors, and the channels are oriented within the support block so that a central axis of a fluid stream injected from each channel over the target area is centered between longitudinal boundaries defined by a respective sector.

摘要： An integrated air separation process produces an O2-enriched gas stream and an N2-enriched gas stream in an air separation unit. The N2-enriched gas stream is heated in a first heat exchanger associated with a first boiler and then power is generated from the heated gas stream. The O2-enriched gas stream is introduced with fuel to a combustor associated with the first boiler, producing flue gas. At least a portion of the flue gas exiting the first boiler is used to generate power. In a preferred embodiment, another portion of the flue gas exiting the first boiler is recycled to the first boiler, as a temperature controlling fluid.

摘要： This invention is related to so-called combined cycle co-generation installations, and it addresses present concerns of the industry. Among these, combustion stability, corrosion (due to large water content in the flue gases), large heat transfer areas, and the like. In some embodiments, an additional heat exchanger is added to heat combustion air with a portion of the exhaust gases resulting from an engine, preferably a gas turbine. As a result, the efficiency of the cycle will improve, the oxidant will be enriched by above 50% oxygen, the combustion process will be enhanced, and the dimensions of the boiler may be reduced. It is considered that the combustion air will require between 10% and 80% of the total flue gas volume, more preferably between 20% and 40%. This is the portion of the flue gases sent through the heat exchanger. A control system designed to optimize the flow of the different streams is also presented. Other inventive embodiments forego heat exchanges in lieu of precise control of two flows of exhaust gas, with preferred addition of additional oxidant to the boiler bumers.

摘要： A system and method for increasing the amount of oxygen in a kiln chamber is disclosed. The radial surface of a rotatable kiln is provided with at least one oxidant injection port extending through the radial surface into the kiln chamber. A cam is connected to the radial surface adjacent the oxidant injection port. A valve assembly including a valve chamber in fluid communication with an oxidant supply is mounted adjacent the kiln substantially in fixed spatial relation with the rotatable kiln body. The valve assembly includes a follower member adapted to contact a surface to the cam to actuate the valve assembly. Rotation of the kiln body brings the cam into contact with the follower member, thereby actuating the oxidant injection assembly, and injecting oxidant through the injection port into the kiln chamber.
