The ignition delay times of CH4/C2H6/C3H8 mixtures representative of an average natural gas composition have been measured in a rapid compression machine (RCM) at the University of Lille. The pressure at the end of compression (EOC) varied from 13 to 21 ba ...
In the context of the liberalization of the European natural gas market former monopolists face a challenge to react to market opening by realigning their strategies. Three major groups of companies can be identified that are capable to influence the Europ ...
Biogas as renewable source of energy is underexploited. We extrapolate the potential recoverable from waste streams in the EU-15 to 769 PJ (17.5 Mtoe), of which under 10% is used (1.7 Mtoe). SOFC can promote the valorisation of biogas in small CHP installa ...
Nowadays, most of the natural gas conversion systems available on the market for bifuel vehicles are based on the venturi principle or on the continuous injection principle for the carburation of the engine. Even if the driveability of these systems is sat ...
This work is part of ongoing research on stationary natural gas engines equipped with unscavanged prechambers. Spark ignition inside the prechamber has been successfully proven with natural gas as well as biogas, reducing emissions while keeping good effic ...
The modelling of natural gas combustion with detailed as well as reduced kinetic mechanisms has been subject to many publications already. Most of the mechanisms are validated at higher temperatures and ambient pressures. Only recently - in parallel to a g ...
The content of this report is property of HTceramix and subject to restrictive distribution The goal of the project "Oxygen membranes for the partial oxidation of natural gas" was the pre-industrial evaluation of the concept of an electroceramic reactor, c ...
Gaseous fuels produced, for example, by waste or agricultural by-products fermentation (biogas) can be burned in-situ by cogeneration systems like spark-ignition internal combustion engines. However, the more and more stringent legislation for exhaust gas ...
The object of this work is to test the unscavenged prechamber ignition system on a 150 kW cogeneration engine feed with biogas. The engine performances in term of fuel conversion efficiency are observed and the reduction potential f the exhaust emissions b ...
