Understanding the Combustion and Extinguishing Mechanisms of Hydrocarbon Fuels

Dear Colleagues,

The growing demand for energy resources as well as the rising cost of generated energy increases the number of research projects related to the more efficient combustion of hydrocarbon fuels. In order to enhance the economic efficiency of fuel, to reduce the harmful effects of combustion products on the environment, and in connection with increased fire safety requirements, it becomes increasingly necessary to strengthen the control over combustion and extinguishing processes, as well as to develop new progressive technical solutions. Currently, technologies based on alternative fuels, i.e., natural gas hydrates, coal mixtures, biodiesel, biogas, as well as coal and oil sludge, are being intensely developed. Modeling the combustion and extinguishing of these fuels is a complex and unsolved problem. Understanding the combustion and extinguishing mechanisms of both traditional hydrocarbon fuels and low-grade hydrocarbon mixtures (sludge), as well as fuels based on natural gas hydrates, will increase the economic efficiency of fuel and reduce the release of dangerous gasses during combustion.

A fire, like any other major disaster, threatens social development and public safety, so fire protection has become an integral part of both the social sphere and the production process. Fires involving flammable liquids may create emergency situations due to the accidental leakage of liquid fuel during its production, storage, and transportation. Liquid fuels are difficult to extinguish due to high rates of heat generation, evaporation, and burnout, as well as due to high fluidity. At the same time, the combustion products of such liquids contain harmful substances that are dangerous to human life and health. Fire extinguishing agents are an important part of active fire safety. In case of fires with liquid fuels, foam products have become the most popular. At the same time, promising technologies include the joint use of traditional and non-traditional agents. For example, gas hydrates of non-flammable gasses can effectively fight fires in confined spaces due to the rapid release of inert gasses and water vapor. The effectiveness of fire extinguishing may be improved by the combined use of emulsions, solutions, suspensions, foams, and non-flammable gas hydrates at different stages of a fire (pyrolysis, initial combustion, intense flame combustion, and smoldering). At the same time, both the consumption of extinguishing agents and the time of fire extinguishing may be reduced by using multiphase compositions.

We are pleased to invite researchers to contribute to the creation of a Special Issue devoted to various aspects of the combustion and extinguishing of hydrocarbon fuels.

• Combustion and extinguishing of hydrocarbon fuels;
• Combustion and extinguishing of gas hydrates;
• Harmful emissions;
• Extinguishing liquid and solid fuels;
• Kinetic modeling;
• Reaction mechanism.

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. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short 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 thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Fire is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
