ANALYSIS OF ENUGU COAL

ANALYSIS OF ENUGU COAL

ABSTRACT

The project Analysis of Enugu Coal was done to determine the characteristic properties of Enugu Coal with particular emphasis on the proximate and ultimate analysis.

Coal samples from the Enugu Coal (Onyeama) mine were obtained and pulverized.  The coal sample (pulverized) was subjected to proximate and ultimate analysis to determine its characteristic constituents.

Analysis showed a volatile matter content of 37.46 weight percent, 7.10% moisture content, 8.3% ash content and 47.14% fixed carbon for proximate.

And, the ultimate analysis showed a 5.2% hydrogen, 63.3% carbon, 0.79% sulphur, 0.8% nitrogen and 28.91% oxygen.

From this, it was reach that Enugu Coal is classified as sub bituminous and therefore is non-coking (low grade fuel).

CHAPTER ONE

1.0              INTRODUCTION

Coal is an amorphous substance derived by the carbonization of vegetation of prehistoric ages, containing free carbon and different hydrocarbons and also complex substance carrying oxygen’s, sulphur and nitrogen, contaminated with various amounts of mineral matter, such as pyrites, gypsum, lime, magnesia, silica, soda and potash found in beds or viens in the earth and used as fuel.  It is brittle, compact, massive and sometimes laminated, and varies in colour from black to brown.

Coal has also been defined in many ways but perhaps the most explicit definition is that “coal is a combustible organic rock having its origins in the accumulation and partial decomposition of vegetation.

Coal is widely distributed, and reserves of it are sufficient to last hundreds or thousands of years.  It has long been the backbone of industrial life.
