Reasons for tangerine peel utilization in the composition of mixed fuels based on bituminous coal

Abstract

Application analysis of processed tangerine peel in a mixture with T grade coal (lean) as a fuel for hot water boilers is presented. Technical characteristics, as well as conditions and ignition delay times for such mixed fuels at different mass concentrations of the initial components, have been experimentally determined. The experiments were carried out in air at temperatures from 600 ° C to 800 ° C. Record of ignition and combustion processes of composite fuel samples was carried out using a high-speed video camera (image format — 1024 Ч 1024 pixels, frame rate — up to 1000000 per second), which ensures high discretization of the recording results of characteristic process times. A temperature limit has been identified for the stable ignition of such fuels. It has been established that an increase of tangerine peel proportion in the mixture leads to acceleration of ignition processes of the studied mixed fuels. Reasons for application of fuel mixtures based on bituminous coal and food waste in the small energy sector have been provided.
