BROWN COAL LOW-TEMPERATURE DRYING FOR POWER PLANTS - INFLU-ENCE OF THERMO-KINETICAL PROPERTIES ON EFFICIENCY OF BROWN COAL DRYING PROCESS

摘要：

　　The authors conducted series of experiments using an experimental brown coal drying system applying fluidized bed method in the low medium (air) temperature: 25 ÷ 75°C.The study was carried out using brown coal from Belchatow and Turoszow deposits,tests concerned the grain size in range: 0÷0.4,0.4÷2,2÷4,4÷6.3 and more than 6.3 mm.In the paper are presented the thermo - kinetical properties of studied coals,inter alia: the effect of grain size,moisture content and structure of coal on the intensity of the drying process is determined as a function of changing temperature of the heating medium and the duration of the process.In addition by monitoring the drying process parameters,curves of the energy input for evaporation of 1 kg water from wet brown coal were estab-lished,thus setting the optimum area for the parameters of the drying process.
