摘要： The flue gas temperature coming from an air preheater to a particulate collection device such as an electrostatic precipitation or fabric filter is reduced to improve the operation of the particulate collection device. This may be done by reducing the exit flue gas temperature from the air preheater or reducing the temperature after exiting. In one embodiment, air in excess of that needed for combustion is passed through the air preheater with the heated excess air either being dumped or used for a variety of purposes in the plant. A particular embodiment involves segmenting the air outlet side of a rotary regenerative air preheater and withdrawing the excess air from the segment where the dust loading is the lowest. Further, additional cooling of the flue gas can be provided by reducing the quantity of primary air that typically bypasses the air preheater and then providing other ways to control the primary air temperature to the pulverizers. The flue gas temperature may also be cooled after the air preheater by heat exchange or spray cooling with water.
摘要翻译：来自空气预热器的烟道气体温度降低到诸如静电沉淀或织物过滤器的颗粒收集装置，以改善颗粒物收集装置的操作。这可以通过减少来自空气预热器的出口烟道气温度或降低出口后的温度来完成。在一个实施例中，超过燃烧所需空气的空气通过空气预热器，加热的过量空气被倾倒或用于工厂中的各种目的。一个具体实施例涉及分段旋转式再生空气预热器的空气出口侧，并从灰尘负荷最低的区段抽出多余的空气。此外，可以通过减少通常绕过空气预热器的一次空气的量，然后提供控制粉碎机的一次空气温度的其它方式来提供烟道气的附加冷却。烟气温度也可以在空气预热器之后通过热交换或用水喷雾冷却来冷却。

摘要： A method for removing mercury from flue gases generated by the combustion of coal comprises: storing a starter batch of activated carbon in an agglomerated state; de-agglomerating the starter batch in a separation device to create a contact batch of activated carbon; transporting the contact batch to a contact location; injecting the contact batch into contact with the flue gas at a contact location having a temperature between 400° F. and 1100° F., whereupon the activated carbon of the contact batch adsorbs mercury from the flue gas; and removing the activated carbon having mercury adsorbed thereon from the flue gas. The transporting step is conducted with substantially no intermediate storage of the contact batch following the de-agglomeration of the starter batch to prevent re-agglomeration of the activated carbon prior to injection.

摘要： A method in which a parent hydrocarbon-rich material is processed so as to produce both a carbon-rich solid material that has a higher carbon to hydrogen ratio than that of the parent material and a carbon-deficient combustible gas that has a lower carbon to hydrogen ratio than the parent material. In the process, the material is activated by exposing it to a hot gas stream having elevated levels of one or both of carbon dioxide and water vapor. The combustible gas is combusted to produce heat. At least about 80% of the heat is used in one or more endothermic steps that include drying coal or biomass.

摘要： The present invention relates to use of carbon-based sorbents such as activated carbon for controlling vapor phase mercury emissions in coal-fired power plant flue gases or waste incineration flue gases. The invention features new methods that improve the performance of carbonaceous sorbents for mercury control compared to the previous methods. One method consists of injecting the sorbent (consisting of at least some carbonaceous material) into the flue gas where the flue gas temperature is at a value above about 1100° F. and below about 2000° F. The invention also consists of injecting the sorbent within or upstream of an economizer section in a coal-fired power boiler. Injecting the sorbent at the locations indicated above, rather than further downstream, provides increased residence time for contact between the flue gas and the sorbent resulting in increased mercury capture, improved sorbent utilization, and improved fly ash properties.
摘要翻译：本发明涉及使用碳基吸附剂如活性炭来控制燃煤电厂废气或废物焚烧烟气中的气相汞排放。本发明的特征在于，与先前的方法相比，改进了用于汞控制的碳质吸附剂的性能的新方法。一种方法包括将吸附剂（由至少一些含碳材料组成）注入到烟道气中，其中烟道气体温度高于约1100°F并低于约2000°F。本发明还包括将吸附剂在燃煤电力锅炉的节能器部分内或上游。在上述位置注入吸附剂，而不是进一步下游，为烟道气和吸附剂之间的接触提供了更长的停留时间，从而导致汞捕获量增加，吸附剂利用率提高，飞灰性能得到改善。

摘要： A method of producing a calcined raw meal and of producing additional steam in an existing steam generator comprises the following steps: pulverized raw meal, hydrocarbon, primary air and secondary air are fed to a calciner system (60), wherein the raw meal is calcined in a temperature range between 850° C. and 950° C., the calcined raw meal is separated from the calciner flue gases at the exit of the calciner system, the calcined raw meal is directed through a cooler (70), in which it exchanges its heat with the secondary air, the calciner exhaust gases are directed in the gas path of the backpass of the steam generator (1) at an appropriate temperature window and are used for steam production. The raw meal consists mainly of limestone (CaCO3) and the calcined material is mainly lime (CaO). The fuel feed (4) to the steam generator (1) is reduced during introduction of the exhaust gases into its backpass.
