Paperback. Condición: New. Print on Demand. This book introduces a simplified formula that allows coal values to be calculated by considering only one term for ash and one term for sulfur. The author presents mathematical derivations establishing the validity of the simplified formula for calculating coal caloric values and compares the results to those obtained using the original Parr formula, showing close agreement. The book also examines the relationship between the sulfur factor and the rank of coal. The author provides a useful discussion of coal formulae, including their advantages and disadvantages. This book will be of interest to professionals in coal science and engineering, as well as those with an interest in understanding the complexities of coal analysis. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
