About this Item

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. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.

About this title

Synopsis

Simplify coal calorific values with a practical approach that saves time and improves consistency. This collection presents a clarified method for calculating unit coal calorific values without replacing established formulas. It includes a proposed simplification of the Parr unit coal formula, ash-to-mineral matter corrections, and the idea of using unit coal as a basis for standardization in Illinois coals. Ideal for professionals in coal analysis, thermochemistry, and industrial testing.

Blend theory with practice through a new factor that combines key corrections into one adjustable value. The book explains how sulfur, ash, and hydration influence results and shows how to apply the simplified method to real samples. It also covers graphical methods for estimating pure coal calorific value and demonstrates standardization approaches that rely on unit coal values.

• Learn a practical modification of the Parr unit coal formula that remains accurate within experimental error.


• Understand how ash, sulfur, and mineral hydration affect calorific calculations.


• See how unit coal values can support coal standardization in a local or regional setting.


• Explore a graphical approach to determining pure coal calorific values and compare methods.

Ideal for readers working with coal analysis, calorimetry, and standardization in laboratories and industry.
