摘要： This invention discloses the synergistic integration of solid fuel combustion, low NOx control technologies (such as Low NOx Burners, reburning and Advanced Reburning) with partial in-duct gasification of coal or other solid fuels. For partial gasification, the solid fuel can be transported and injected by recycled flue gas stream at 600-800° F. in the reburning zone or in the upper section of the main combustion zone of a boiler. This allows the fuel to be preheated and partially pyrolyzed and gasified in the duct and then injected into the boiler as a mixture of coal, gaseous products, and char. Gasification increases coal reactivity and results in lower carbon-in-ash levels. As an option, the gaseous and solid products can be split using a cyclone separator. Splitting the gasified fuel stream will allow the volatile matter to be used for reburning and the fixed carbon to be injected into the high-temperature main combustion zone.
摘要翻译： 本发明公开了固体燃料燃烧，低NOx控制技术（如低NOx燃烧器，再燃烧和高级再燃烧）与煤或其他固体燃料的局部管内气化的协同一体化。 对于部分气化，固体燃料可以在再燃烧区域或锅炉主燃烧区上部的600-800°F的再循环烟气流输送和注入。 这允许燃料在管道中被预热和部分热解并气化，然后以煤，气体产物和焦炭的混合物注入锅炉。 气化提高煤的反应性，并导致较低的灰分含量。 作为选择，气体和固体产品可以使用旋风分离器分离。 分解气化燃料流将允许挥发性物质用于再燃烧，并将固体碳注入高温主燃烧区。
