摘要： An atomizer comprises a cylindrical mixing chamber with open entry and discharge ends. An inner barrel for a slurry or fluidized dry powder is connected to the entry end for supplying the slurry or fluidized fine powder into the mixing chamber. One or more atomizing gas ports extend at an angle into the mixing chamber for supplying atomizing gas to be thoroughly mixed with the slurry or fluidized dry powder in the mixing chamber. The atomizing gas ports are spaced upstream from the discharge end by from one to five times the diameter of the mixing chamber, and downstream from the entry end. A larger diameter volume chamber communicates with the discharge end of the mixing chamber and has at least one nozzle which permits the homogenized mixture to exit therefrom. An impact surface is positioned opposite the discharge end. The at least one nozzle is positioned around the impact surface. Critical dimensional and positional features for the mixing and volume chambers, the atomizing gas ports, and the at least one nozzle produce efficient atomized sprays even at low flow velocities for the slurry or fluidized dry powder and the atomizing gas.

摘要： A dual-fluid low pressure drop atomizer utilizes extended wear life material and comprises a nozzle head having a secondary mix chamber therein for receiving a mixture of a first compressible fluid and a second fluid containing solids from a primary mix chamber. The nozzle head also has an orifice therein communicating with and adjacent to the secondary mix chamber for discharging a jet of the mixture. The orifice and the secondary mix chamber form an approximate right angle therebetween. An inner barrel is connected to the nozzle head at the primary mix chamber and supplies the first fluid to the nozzle head. An outer barrel is arranged around the inner barrel creating an annulus therebetween and is also connected to the nozzle head for supplying the second fluid to the nozzle head. Wear resistant material provided in the primary and secondary mix chambers reduces erosion within the atomizer head.

摘要： An asymmetrical, or non-uniform arrangement of heat exchanging tubes in a second stage heat exchanger of an integrated flue gas treatment system provides improved flow characteristics and reduces or eliminates flooding caused by the counter-flow of upwardly rising flue gases and downwardly falling reagent and condensate through the heat exchanging tubes. The non-uniform spacing produces a non-uniform velocity profile with at least one low velocity region in each row, allowing reagent and condensate to drain downward at said low velocity region, thereby preventing high gas phase pressure drop caused by the onset of flooding. Embodiments are provided in which one of every six tubes are removed from each row in a uniform array of tubes, or one of every four tubes are removed from each row in a uniform array of tubes. Other asymmetrical, or non-uniform spacings are possible.

摘要： A scoop is used to collect a liquid slurry upstream of an internal collection tank. The scoop is in fluid communication with a downcomer, which receives at least part of the collected slurry, thereby maintaining a continuous flow of liquid slurry through the scoop to prevent plugging. Collected slurry can be removed for treatment from the scoop or the downcomer. In an application to a wet flue gas desulfurization (FGD) scrubber, the scoop collects an effluent slurry of partially reacted liquid scrubbing reagent and scrubbing byproducts before they drain into an internal reaction tank. Partially reacted liquid scrubbing reagent and scrubbing byproducts can therefore be withdrawn for treatment before the addition of fresh reagent alters the pH of the treatment stream.

摘要： A two-stage flue gas treatment condensing heat exchanger system allows for flue gas to be passed into a two-stage housing at an inlet of the housing. The flue gas is channeled downwardly through a first stage of the housing having a first condensing heat exchanger which cools the flue gas. The flue gas is then upwardly channeled in the housing through a second stage having a second condensing heat exchanger which is located near an outlet. A collection section is located between the first stage and the second stage of the housing for collecting liquids, condensate, particulate and reaction product. Steam is injected into the housing at a plurality of locations for enhancing particulate removal.
