A new type of oven for continuous low-temperature carbonization of coal by solar energy is discussed. Carbonization time was estimated and comparisons of all kinds of carbonization methods were carried out. The article discusses the advantages such as shorter carbonization time, energy savings and zero pollution, and that solar energy can be changed into chemical energy of tar and gas and stored in them. Trends concerning solar energy application to the field of coal transformation are outlined.
