Abstract: A body is provided with at least two cylindrical swirl chambers used to form a liquid spray cone for injecting charge gases resulting from charging coal to the coke oven, and a liquid spray cone for cleaning coke-oven gas passing through the coke oven ascension pipe. The swirl chambers are made of different diameters and each has a separate tangentially oriented inlet and a separate axially directed spray nozzle. The chambers communicate with one another through a by-pass passage to provide flow of liquid from one swirl chamber to another one.

Abstract: The electrochemical cell according to the present invention comprises an anode of a metal capable of reducing sulphur dioxide, an inert porous cathode with the electron-type conductivity, preliminarily anodically polarized to a potential of from 4.5 to 4.7 V relative to a lithium electrode, and a non-aqueous electrolyte containing sulphur dioxide as a cathodic depolarizer, at least one aprotic organic solvent with a donor number of from 20 to 50, and an electrolyte salt which is inert relative to sulphur dioxide and the anode metal.
