Description | ||||||
The present research work is emphasized on exploring alternative uses of low rank indigenous coals, particularly Tigyit coal and Samlaung coal as Secondary Fuel Mixtures (SFM). The characteristics such as moisture, ash, volatile matter, fixed carbon, sulphur contents and calorific value of Tigyit and Samlaung coals were determined. The morphological nature and elemental composition of Tigyit and Samlaung coals were also evaluated based on the monographs of Scanning Electron Microscopy (SEM) method and Energy Dispersive X-Ray Fluorescence (EDXRF) method. The sulphur content of run- of- mine coal was reduced using washing operation The quality of prepared fluid carbon is related to its ingredients, such as, size of coal, amount of water added and nature of stabilizer being used. Among the various laboratory tests available for fluid carbon performance test: settling, specific gravity and viscosity were chosen as basic tools for the present work. An appropriate amount of (-200) mesh size coal to water, 60:40, and stabilizer and initiator would have a viscosity such that it would behave like a truly fluid mixture in the piping system during test-firing. The combustion characteristics of prepared fluid carbon were simulated by two diverse firing systems: improvised static firing in make-shift cylindrical furnace and continuous dispersion / injection system. In the test-firing of prepared fluid carbon by continuous dispersion system, water vapour in the flame catalyses and accelerates the combustion of the carbon residue and exhibited continuous self-sustaining complete combustion. |
