    because the. high rank coals have higher amount of volatile matter. ratio of fixed carbon to volatile matter increases. oxygen content progressively decreases. calorific value of the coal increases. Answer : 2 so additional design of coal preparation plant or coal washing plant is required for further treatment.Washability characteristics of the coal washing plant were evaluated using fractional washability values of the lignite coal. Float-sink tests were made on using sized samples at 90-50 mm and 50-1 mm.After this the residual slurry was tested for its calorific value and ash content (%) to derive its The calorific value of all the samples was tested on the fuel value. Bomb Calorimeter. The calorific value of pure cotton is Pre-treatment can be adopted as a solution for tested to be 3845.8 cal/gm.Feb 16,
