摘要： A low NOx combustion method includes steps of injecting reactants into a combustion chamber. A primary reactant stream, including fuel and combustion air premix, is injected from a premix burner port into the combustion chamber. A staged fuel stream is injected into the combustion chamber from a staged fuel injector port adjacent to the premix burner port. A stream of recirculated flue gas is injected into the combustion chamber from a flue gas injector port that is adjacent to the premix burner port and adjacent to the staged fuel injector port. In this manner, the stream of recirculated flue gas is injected into the combustion chamber unmixed with the primary reactant stream and unmixed with the staged fuel stream.

摘要： A low NOX burner in which the amount of air flow to the low NOX (nitrous oxides) burner can be adjusted (e.g., based on determinations related to the TEG air flow to the low NOX burner). A low NOX burner capable of operating in a TEG mode that uses a mixture of fresh air and turbine exhaust gas (TEG) as an oxidizer, and also in a fresh air mode in which fresh air (but not TEG) is used as an oxidizer (e.g., and that may be configured to switch seamlessly between these modes). A method of operating a low NOx burner that that includes using TEG and fresh air as an oxidizer to burn fuel, in a TEG mode and, when conditions dictate, such as when the TEG flow has decreased to a pre-determined level (e.g., zero or close to zero), switching from the TEG mode to a fresh air mode.

摘要： An exhaust gas recycling control system includes a combination device, having inlet and exhaust ends. The exhaust end is connected to the inlet end by a recycling tube which has a control valve to control an open or closed state. An oxygen sensor mounted detects oxygen content in an exhaust gas and convert the oxygen content detected signal into a voltage signal sent to a controller. The controller controls the control valve to open or close. When the oxygen content of the exhaust gas is higher than a threshold, the control valve opens and a high oxygen content of exhaust gas flows through the recycling tube to the inlet end.

摘要： A system for drying solid fuels prior to injection and burning in solid fuel boilers is described. High moisture content solid fuels such as bark, sludge, wet coal, are preferably dried to some degree before they can burn. The present invention incorporates a delivery chute in which combustion gases dry the solid fuel before it reaches the combustion chamber of the boiler. In one embodiment, the combustion gases are drawn through the delivery chute to remove moisture from the incoming fuel and then the gases flow back into the boiler. A second embodiment directly exposes the wet fuel to the combustion in the boiler for a sufficient time to remove a substantial amount of moisture before the fuel is spread onto the solid fuel combustion region.

摘要： A combination of parallel processes is disclosed to provide optimal re-mediation operations for contaminated soil. Soils with high levels of heavy petroleum hydrocarbons are directed to a thermal process for destruction in a combustion process. Carbon dioxide generated and recovered in the thermal process is employed as a solvent in a solvent process to clean other soils of petroleum hydrocarbons and certain chlorinated hydrocarbon compounds. In the solvent process, contaminated soils are run through a closed soil separator where the soils are washed with carbon dioxide. The carbon dioxide is then dried from the soil and the soil is sent for segregation. Soils with the lightest forms of hydrocarbon contamination (gasoline, etc.) are subjected to a vaporization process utilizing heat energy generated in the thermal process to heat the soil, under a partial vacuum, and the vapors generated are captured, condensed, and recovered as product.

摘要： A burner head has at least two and preferably four openings (45) in an aperture plate (37), with uniformly inclined guide blades (23) for the delivery of incoming air in the direction of an axis (31) to a combustion chamber (15) in the form of incoming air jets (53) intersecting one another in the chamber. Between the openings (45), blocking blades (27) are embodied, for forming peripheral underpressure zones (55) between the incoming air jets (53). The incoming air jets (53) are deflected by the guide blades (23) into a position that is inclined relative to the axis (31). The incoming air jets (53) therefore diverge and as a result create a central underpressure zone (57) about the axis (31) between the incoming air jets (53). By means of the central underpressure zone and the inclination of the incoming air jets, a rotation of the incoming air is achieved. In operation of the burner, hot gases from outside are aspirated into the peripheral underpressure zones (55) and, counter to the flow direction of the incoming air, into the central underpressure zone (57) between the incoming air jets (53). These flow conditions create ideal conditions for the combustion of gaseous, liquid and/or particulate fuel in a calm, cool, low-polluting flame. This combustion is practically independent of the size and shape of the combustion chamber and of the pressure conditions in the combustion chamber, for combustion installations of 16 kW to 1000 kW, or more.
摘要翻译：燃烧器头部具有在孔板（37）中的至少两个且优选四个开口（45），具有均匀的倾斜导向叶片（23），用于将进入的空气沿轴线（31）的方向输送到燃烧室 15）在腔室中彼此相交的进入空气射流（53）的形式。在开口（45）之间，实现了阻挡叶片（27），用于在进入的空气射流（53）之间形成周边的负压区（55）。进入的空气射流（53）被引导叶片（23）偏转到相对于轴线（31）倾斜的位置。因此，进入的空气射流（53）发散，因此在进入的空气射流（53）之间围绕轴线（31）产生中心负压区（57）。通过中央负压区和进气喷射器的倾角，可以实现进气的旋转。在燃烧器的操作中，来自外部的热气体被吸入到外部负压区（55）中，并且与进入的空气的流动方向相反地进入入射空气射流（53）之间的中心负压区（57）。这些流动条件为平静，冷却，低污染的火焰中的气态，液体和/或颗粒燃料的燃烧创造了理想的条件。这种燃烧实际上与燃烧室的尺寸和形状以及燃烧室中的压力条件无关，燃烧装置的功率为16kW至1000kW。
