Abstract: Flue gases (6) discharged from a flue gas desulfurizer (5) are fed to an absorption tower (7) and the heat recovered by the absorption is transferred to the flue gases and/or the absorbent (8). The water which has been absorbed by the absorbent is expelled therefrom as vapor by desorption, e.g., by a stripping with flue gas in a preliminary scrubber (44), which precedes the flue gas desulfurizer (5). By means of a pump (16) the absorbent (8) is circulated between the absorption tower (7) and the preliminary scrubber (44). The flue gases (4) discharged from the boiler furnace (1) flow through an air preheater (2), the preliminary scrubber (44), the flue gas desulfurizer (5) and the absorption tower (7), in that order, and are then discharged into the open through a chimney (19).

Abstract: A bulk process is described which is capable of producing large area sheets about 8 micrometers thick having the property of light/electric power conversion at extremely high production rates (many m<2>/s) at low cost ( DOLLAR 1/m<2>). The devices have an inherently high efficiency 60-80% when laminated in an assembly to utilize both resolved light vectors. A light/electric power converter is described comprising a sheet containing oriented dipolar conducting linear structures forming an antennae array capable of absorbing light photons and producing a unidirectional electric current. These linear structures constitute submicron antennae and femto diode circuit elements. The individual antenna-circuit elements are self-ordered into the linear structure using a bulk process. The process utilizes (1) electro-ordering a suspension of elongated submicron metal crystals; or (2) molecules capable of absorbing a light photon and converting its energy to electric energy; or (3) visco-elastically stretch-orienting a light-electric responsive preformed heteropolymer. These submicron linear structures comprise a plurality of quantum well-steps, each with an assymetric tunnel junction at one end, in ordered three dimensional arrays. The manufacture uses a simple low cost bulk process and does not employ the submicron facility needed for the earlier planular process.
