Abstract

1527661 Nozzles DAVY POWERGAS GmbH 10 Feb 1976 [15 Feb 1975] 05131/76 Heading B2F [Also in Division C1] Waste sulphuric acid is thermally cracked to form a gas containing sulphur dioxide (see also Division Cl) by injecting a fuel and the waste acid into a high-frequency sonic field and combusting the fuel in a cracking zone. The head 1 of the high-frequency atomiser nozzle is shown in Fig. 2. Acid is supplied through the central tube 2 which terminates in a pressure-operated atomiser-nozzle 5. Heating gas is supplied through annular duct 3 and a "sonic" gas (e.g. oxygen) is supplied through an outer annular passage 4 to a resonance chamber Y where the highfrequency field operates on the gas-mixture. The frequency is between 10KHz and 1000KHz, preferably above 20KHz.
