METHOD FOR HEATING BAUXITE PULP Russian patent published in 2003 - IPC

Abstract RU 2217374 C2

FIELD: heat technology. SUBSTANCE: method for heating bauxite pulp involves its continuous pumping through autoclave device with preliminary heating pulp using steam and final heating pulp up to reaction temperature. Preliminary heating pulp is carried out for two stages: firstly, by spent steam method using steam from self-evaporation of leached pulp and then by contact method using steam from self-evaporation of leached pulp or removal steam from turbines of central heating and powder plant. Invention provides the enhancement of effectiveness in heating bauxite pulp and economy of live steam. Invention can be used in production of alumina in sphere of autoclave leaching bauxite. EFFECT: improved heating method. 1 dwg
