Granulating of coal fines using peat

Abstract

The paper determines the optimal composition of fuel to use in solid-fuel boilers. The primary goal of this report is the development of the combination of coal fines with peat without additives and binders for producing a more stable and cohesive granules. Another objective is a peat that to reduce the emission of sulfur dioxide during the coal peat fuel combustion and increasing the efficiency of the briquetting process. Finally, an objective of the report is a peat that can be produce inexpensively. Therefore, according to these and other objectives, the present report consists of the combination of coal fines with peat. The coal fines with peat are mix and the resulting well mixed mass is then pelletizing by the application of pressure in conventional equipment – stiff extrusion. The coal fines and peat was conditioned at various moisture contents to observe the effects on the finished product. The material then agglomerated into a granular product. The content of the granular product was 2:1, 1:1, 1:2 by volume. When the moisture content was increase to 65% by weight, moist pellets were formed. The next step in the evaluation was to determine what actual condition was acceptable to blast furnaces. A simple test was performed on the agglomerated coal fines to confirm the dedusting efficiency.
