摘要： An in-situ forced oxidation wet flue gas desulfurization apparatus, method and arrangement for utilization with oxy-fuel combustion power plants. The apparatus is a tower-like structure having a flue gas scrubbing zone and a reaction zone located subjacent to the gas scrubbing zone. A sulfur oxide absorbing liquid slurry is supplied to the gas scrubbing zone to react with and scrub the sulfur oxides from the flue gas. The partially reacted liquid slurry reagent and the scrubbed products drain into the reaction zone, rising to a set level. Oxidation air is introduced into the liquid slurry in the reaction zone to force the in-situ oxidation of sulfur compounds collected in the reaction zone. A wall separates and communicates the gas scrubbing zone and the reaction zone, the wall prevents the oxidation air from entering the gas scrubbing zone and extends into the liquid slurry below a nominal depth required to establish and maintain a liquid slurry seal thereby substantially precluding the leakage of flue gas into the reaction zone while allowing the partially reacted liquid slurry reagent and scrubbed products to drain into the reaction zone.

摘要： An apparatus for low-temperature NOx-reduction is disclosed, which is useful in boiler installations used at electric-generating plants. The apparatus employs one or a plurality of moving-bed reactors wherein a moving bed of common base-metal catalyst is used for selective catalytic reduction of NOx present in flue gas. The moving bed permits continuous introduction of fresh or regenerated catalyst, thus obviating the conventional problems of sulfur-poisoning and consequent reduction in catalytic activity with such catalysts. Due to the lower activation energies of such catalysts, an SCR utilizing the moving-bed reactors disclosed herein can be located downstream of the air heater, further improving electric-generating efficiency. Methods for low-temperature NOx reduction are also disclosed.
摘要翻译：公开了一种用于低温NOx还原的装置，其用于在发电厂使用的锅炉装置中。该装置采用一个或多个移动床反应器，其中使用普通基础金属催化剂的移动床来选择性地催化还原存在于烟道气中的NOx。移动床允许连续引入新鲜或再生的催化剂，从而消除了常规的硫中毒问题，从而导致催化剂的催化活性降低。由于这种催化剂的活化能较低，所以利用本文公开的移动床反应器的SCR可以位于空气加热器的下游，进一步提高发电效率。还公开了低温NOx还原的方法。

摘要： An integrated air foil and ammonia injection grid provides a plurality of air foils across a flue conveying flue gas. Each air foil has a leading curved edge and a tapered, pointed, trailing end. At least one injection pipe is positioned inside each air foil, and has at least one nozzle for injecting ammonia into the flue gas flowing across the air foils. Preferably, plural injection tubes are provided and positioned one behind the other in each air foil, and each injection tube in a given air foil has a length different than a length of the other injection tubes in the same air foil. A longest injection tube in a given air foil is located furthest downstream and proximate the tapered trailing edge and a shortest injection tube in the same air foil is located furthest upstream, remaining injection tubes in the same air foil being progressively shorter the further upstream any injection tube is located. Apertures may be provided on opposed lateral sides of the air foils for introducing a gas flow into the flue gas passing across the air foils. Ammonia flow to each injection pipe may be individually controlled.

摘要： A process of purifying the gypsum slurry end product produced by a flue gas desulfurization process which incorporates fine solids separation/classifying, dewatering, mixing, and filtering to both achieve a useful gypsum product and to recycle as much process water as possible to the flue gas desulfurization process. This purification process separates the incoming gypsum slurry into a fine solids stream containing a disproportionate amount of impurities therein that are concentrated and subsequently disposed of and a coarse solids stream containing a large amount of gypsum therein from which a usable gypsum product is recovered.

摘要： A device for channeling boiler flue gas flow and injecting controlled amounts of ammonia upstream of a selective catalytic reduction (SCR) NOx removal system. A perforated plate and/or damper can be located within one or more channels to provide volumetric control through a channel. Flow conditioning devices such as static mixing tabs and/or flow straightening tube bundles can optionally be included in each channel to improve mixing and velocity profiles. Gas flow rate measurements made, for example via pressure taps, within one or more channels can be used to measure flow and provide feedback for improved ammonia-to-NOx mole ratio control.
