Coal is an abundant energy resource in the United States, China and many other countries. However, burning coal also carries environmental concerns, such as sulfur compounds, and future concerns regarding carbon dioxide. Clean coal technologies are needed to provide better environmental performance at low cost, enabling power plants to continue using coal for electricity generation. As fossil fuel use increases, the amount of waste materials and the environmental issues dealing with their disposal also increase. One of the promising approaches is the development of coal/waste co-firing technology with fuels such as biomass. To improve efficiency and reduce the cost of electricity, it is important to understand factors such as the operating conditions and the impact of fuel properties and additives on carbon conversion, ash, slag, fouling, etc. In the gasification process, fouling and plugging in the syngas cooler system is the major cause of unplanned downtime. To develop an accurate heat transfer model in any type of coal combustion or gasification process, the heat transfer and the rheological properties of materials such as ash, biomass, and slag, especially in high-temperature environments need to be understood and properly modeled.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed Open Access monthly journal published by MDPI.
