SBIR Phase I: Combustion of Natural Gas with Improved Heat Recovery and Zero NOx Production

里昂 该小型企业创新研究（SBIR）第一阶段项目的目的是开发一种新型燃烧器，该燃烧器将允许天然气的燃烧以空气作为氧化剂，而不混合空气和燃料，从而允许在未稀释状态下回收C0和H2O。该燃烧室还具有零NOx产生的优点。目前可用的天然气燃烧技术受到许多限制。虽然天然气燃烧产生的NOx量因技术而异，但它们都是相似的，因为会产生一些NOx。在诸如南加州的空气质量问题严重的地区，可预防的NOx排放即使相对较小也可能是不可容忍的。现有的天然气燃烧技术也不令人满意，因为它涉及在燃烧过程之前或期间将天然气与空气混合。这导致燃烧过程产生的CO2和H2O被来自空气的氮气稀释。这降低了后燃烧气体中水蒸气的分压，使露点降低到实际上不可能有效回收水的蒸发热的程度。用氮气稀释燃烧产物也使得回收和出售CO2不切实际。这是令人遗憾的，因为存在CO2的大量市场，并且因为可能的全球变暖问题。如果能够经济地从燃烧气体中回收和出售C 〇 2的技术被完全开发，那么在发现这种控制是必要的情况下，它将可用作控制C 〇 2排放的方法。 该技术的初始应用可能限于具有严重空气质量问题的区域，例如南加州，以及其中销售回收的CO2是实际可行的情况。如果它成为控制CO2排放所必需的话，则预期将得到非常广泛的应用。

9560154 Lyon The purpose of this Small Business Innovation Research (SBIR) Phase I project is to develop a novel combustor that would allow the combustion of natural gas to be done with air as the oxidizing agent, without mixing of the air and fuel, thereby allowing C0 and H2O to be recovered in an undiluted state. This combustor also has the advantage of zero NOx production. Presently available technologies for natural gas combustion are subject to a number of limitations. While the amount of NOx produced by natural gas combustion varies from one technology to another, they are all similar in that some NOx is produced. In regions such as Southern California in which the air quality problems are critical, preventable NOx emissions are likely to be intolerable even if they are relatively small. Available natural gas combustion technology is also unsatisfactory in that it involves mixing the natural gas with air prior to or during the combustion process. This causes the C02 and H20 produced by the combustion process to be diluted with nitrogen from the air. This lowers the partial pressure of water vapor in the postcombustion gases, decreasing the dew point to such an extent that useful recovery of the heat of vaporization of water is not practically possible. The dilution of the combustion products with nitrogen also makes it impractical to recover and sell the C02. This is regrettable both because there is a substantial market for C02, and because of the possible problem of global warming. If a technology which could economically recover and sell C02 from combustion gases were fully developed, it would then be available as a method of controlling C02 emissions in the event that such control was discovered to be necessary. Initial applications of this technology are likely to be limited to regions with critical air quality problems such as Southern California and to situations in which it is practical to sell the recovered C02. Very wide spread application is to be expected if it bec omes necessary to control C02 emissions.
