Verbrennungsanlage mit Rauchgaswäsche für die Beseitigung von Chemie-Abfällen

Incineration plant with flue-gas scrubbers for disposal of chemical waste . Incineration plant No. II installed at the Bayer Facilities at Leverkusen/Germany has been in regular operation since November 1977 after a previous one-year period of testing. About 25 000 t of industrial waste per year can be burnt in this plant, simultaneously producing nearly 140 000 t of steam. The plant consists of a bunker building, a rotary kiln and secondary combustion chamber, including all the feeding equipment for solid, viscous, and liquid wastes, as well as a boiler, an electrostatic dust precipitator, and a wet gas cleaning unit. This latter unit consists of an injection cooler (quencher), two rotary scrubbers, and a jet scrubber. The cleaned flue gas is reheated in two heat exchangers and is discharged from a suction blower through a 100 m high chimney into the atmosphere. Around the chimney several measuring instruments are installed to check and continuously record the type and amount of emission. The scrubber water is sent to the company waste water treatment plant; the solid ashes and dust are dumped separately. The average incineration costs are DM 400 per ton of waste.
