Mixture Temperature-Controlled (MTC) combustion is a novel combustion concept for steady-operating applications, such as gas turbines, boilers, and furnaces. Compared to lean premixed burners, it offers significantly lower NOX emission. In order to reduce fossil fuel consumption, alternative fuels can be used as a substitute. Currently, coconut and palm biodiesels were evaluated. Besides the NO and CO emissions, the chemiluminescent signal was also evaluated. It was concluded that this favorable operation mode is easier to achieve with fuels having higher volatility.
