Document Type and Number:
Japanese Patent JPH07507332
Kind Code:
A
Abstract:
The invention concerns a process for drying hydrous solid fuels, in particular raw brown coals, in a drying container of a heat-generating plant. The aim of the invention is to achieve substantial reduction of the CO2? emission per useful effect unit by reduced use of fossil energy carriers; the devices for drying raw brown coal are to be connected to the heat-generating installation in such a manner that the energy of the exhaust vapours is fully utilized. According to the invention, this is achieved by virtue of the fact that the drying container is heated directly by a saturated steam circuit of the heating boiler of the steam-generating plant, the dust-free exhaust vapours under average pressure are fed to a heat supply line and the exhaust vapour condensate is used, following chemical processing, to supply water to a heating plant and/or a heating network.
