Overview
ABSTRACT
The expression solid fuel goes beyond the familiar notion of coal and allows for the connection of all natural coal resources to solid fuels with a fossil plant origin. The common characteristic of such solid fuels is that they contain a high carbon proportion. Yet this apparent unity nonetheless encompasses a great diversity of characteristics and properties, which are the main causes for the technical issues caused by solid fuels in their modern applications.

INTRODUCTION
This dossier is a reprint of "Solid fuels. Characteristics. Properties. Analyse" by Georges PRUDHON, published in 1996. Updated by François JACQUESSON, Juliette LETE and Stéphanie PARIS.
The term solid fuel goes beyond the familiar notion of coal or hard coal, linking all natural carbon resources (biomass, wood, charcoal, etc.) to solid fuels of paleo-plant origin. The common characteristic of solid fuels defined in this way is that they contain a high proportion of carbon. However, this apparent unity conceals a huge diversity of characteristics and properties, which are the main reasons for the technological challenges posed by solid fuels in their modern applications.
Thanks to the rapid accumulation of basic knowledge and the sustained pace of technological progress, the face of coal combustion plants and coking plants has changed dramatically in recent decades, particularly since the oil crisis in the early 1970s. These upheavals have mainly resulted in an increase in plant unit capacity, greater use of automation techniques and the ability to use an ever wider range of coals, as new mines have opened up and new producing and exporting countries have emerged.
