  • Patent number: 5759345
    Abstract: To recover the sodium-sulphur compounds following sodium-based pulp processing, e.g. the ASAM process or basic or acidic sodium sulphite processes, the waste liquor is burnt in a lye burning vat (1) with liquid slag extraction and the exhaust gases are subjected to multi-stage purification with dry fly-ash recovery and the gaseous sulphur compounds are also separated in a multi-stage washing process. The water-soluble components of the fly-ash are taken to the waste liquor to be burnt and thus the sulphur to be recovered in the slag is increased. The slag is dissolved in water and the dissolved sodium compounds are converted by multi-stage carbonisation with a part of the purified flue gas into sodium bicarbonate and H.sub.2 S. The H.sub.2 S is burnt and finally converted into sodium sulphite so that the desired lye for pulping cellulose can be made up from sodium sulphite and carbonate.

  • Patent number: 5587138
    Abstract: The present invention is directed to a process for preventing the formation of dioxin and/or furan during combustion of composite combustible materials in a combustion chamber. The process includes passing the generated combustion gas in a flow from the combustion chamber to a dedusting device, cooled and purified while maintaining the SO.sub.3 content in the combustion gas flow from about 7 to about 500 mg/m.sup.3 and at a temperature of from about 300 .degree. to about 800.degree. C., The process allows at least surface regions of particles of meal dusts contained in the combustion gas to be converted to sulfates and thereby prevent formation of dioxins and furan. The invention also includes a steam generator for carrying out the process whose steel structures coming into contact with the combustion gases are either alloyed or coated with tungsten and/or vanadium on the combustion-gas side.
