A gas combustion treatment method for the combustion treatment of an ammonia-containing gas and a hydrogen sulfide-containing gas, the method comprising a first combustion treatment step in which the ammonia-containing gas, together with a fuel, is introduced and burned; a nitrogen oxide reduction step downstream of the first combustion treatment step, in which a portion of the hydrogen sulfide-containing gas or the ammonia-containing gas is introduced and the nitrogen oxides produced in the first combustion treatment step are reduced in a reducing atmosphere; and a second combustion treatment step downstream of the nitrogen oxide reduction step, in which the remaining hydrogen sulfide-containing gas, together with air, is introduced and burned. The present invention provides a combustion apparatus suitable for use as a combustion furnace for off-gases resulting from the wet purification of coal gasification gas.

Gas combustion treatment method and apparatus therefor

A method and a device for dehydrating a heavy oil wherein an emulsion of water and a heavy oil is mixed in a stirring chamber together with a suitable amount of an emulsion breaker, the mixture is subjected to separation in a two-phase separation tank to a heavy oil-rich component and a water-rich component, the heavy oil-rich component is then fed to a dehydrator of a high voltage charge type in which separation to a dehydrated heavy oil and a water-rich component is effected, the water-rich component fractions supplied from the two-phase separation tank and the dehydrator are mixed in a pipeline, the mixture thus obtained is admixed with an O/W emulsion breaker and then, fed to a stirring chamber and finally separated to a heavy oil-containing component and a heavy oil-free water layer in a second separation chamber.

To provide an electrophotographic printer which can satisfy regulations for exhaust gas emission easily, a printer is provided with a circulation line for taking out and returning gas generated in a casing of the printer, and a heat exchanger, for cooling the gas and for recovering solvent, is provided midway on the circulation line. The heat exchanger lowers a concentration of the gas. A detection sensor detects a temperature and humidity of the gas in the casing and a heater, provided downstream of the heat exchanger, adjusts a humidity of the gas which is then returned into the casing, upon receiving an output of the detection sensor.

Electrophotographic printer

A flue gas treatment system is provided for which is capable of easily treating Se contained in flue gas, comprising an extractor 13 for extracting soluble components in the dust removed by a dry-type dust precipitator 5 into water to slurry the dust; insolubilizer supply 16 for supplying an insolubilizer for insolubilizing at least tetravalent Se to the dust slurry which has been slurried from the dust by the extractor 13; adsorbent supply 14 for supplying an adsorbent composed of an organism material for adsorbing at least hexavalent Se in the dust slurry; and separator 15 for solid-liquid separating the dust slurry to which the insolubilizer and the adsorbent have been supplied by said supplies.

A twin wire sheet-forming apparatus for a paper machine having at least two fixed hydroextractors which have separate places for drainage to the hydroextractor side from places for dispersion of fibers. These hydroextractors are arranged alternately in the two wire loops, and have shoe blades, with a wedge shaped trough in a mid-portion of each shoe blade. The wires do not bend at a front leading portion of each shoe, yet do bend at the mid-portion or back portion of each shoe for generating a pressure pulse to disperse the fibers.

A coating apparatus for applying coating liquid onto a web which is being transported as wrapped around a backing roller includes a chamber from which the liquid is applied to the web and a blade for scraping the applied coating liquid into a film having a constant thickness. A partition plate divides the inside of the chamber into upstream and downstream sections with respect to the direction of travel of the web. A plate-like body resiliently held in contact with the web is mounted to an upper portion of the partition plate, and a plurality of holes are formed in a lower portion of the partition plate.
