1. 1. Sintering in the Kraft Pulp Mill - Studies in the Rotary Kiln and Recovery Boiler

   Författare :Josefina Lindblom; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sintering; recovery boiler dust; recovery boiler; solid state diffusion; rotary kiln; lime mud; lime; sintering model; specific surface area;

   Sammanfattning : The conversion of black liquor to white liquor is carried out in the chemical recovery system, which is made up of several units; in two of them, i.e. the recovery boiler and the rotary kiln, sintering plays an important role. LÄS MER

   Författare :Hans Magnusson; Ulf Germgård; Gunnar Henriksson; Hans Theliander; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; kraft pulping; recovery boiler; smelt properties; non-process elements; oxygen delignification; viscose manufacturing; integrated production; regenerated cellulose; sulfatmassa; fysikaliska egenskaper; smälta; sodapanna; processfrämmande ämnen; bioraffinaderi; integrerad produktion; regenererad cellulosa; Chemical Engineering; Kemiteknik;

   Sammanfattning : Modern chemical technology is an efficient tool for solving problems, particularly within the complex environment of the pulp and paper industry, and the combination of experimental studies, mill data and mass balance calculations are of fundamental importance to the development of the industry. In this study various examples are presented, whereby chemical technology is of fundamental importance. LÄS MER

5. 4. System Aspects of Black Liquor Gasification – Consequences for both Industry and Society

   Författare :Håkan Eriksson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; Black liquor gasification; Biomass; Combined Cycle; Eco cyclic pulp mill; CHP; Electricity production; Recovery boiler; Gas turbine;

   Sammanfattning : The pulp and paper industry consumes large quantities of biofuels (mainly bark and black liquor) to satisfy process requirements. Biomass is however a limited resource, and biofuel usage should therefore be as effective as possible. LÄS MER

7. 5. Characterisation of Fuels and Fly Ashes from Co-Combustion of Biofuels and Waste Fuels in a Fluidised Bed Boiler. A Phosphorus and Alkali Perspective

   Författare :Anita Pettersson; Högskolan i Borås; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; phosphorus recovery; co-combustion; fluidised bed combustion; olivine; Biofuels; zeolites; fertiliser; extraction; refuse derived fuels; kaolin; alkali; sulphur; ash; municipal sewage sludge;

   Sammanfattning : In the efforts to create sustainable production of heat and power and to reduce the net CO2 emissions to the atmosphere, alternative fuels are today being utilised. These fuels are, for example, biofuels and waste derived fuels such as different residues from the agricultural sector and the pulp and paper industry, municipal sewage sludge and municipal sorted solid waste.
