internal combustion engines. Values of entropy production, second law efficiency are calculated, and an objective function …₂, CO and NO_x, are presented for the flue gas of the internal combustion engine. The results show that … entropy generation in the combined heat and power mode is 30% lower than that in the simple internal combustion engine. Also …

The combustion characteristics of both pure propane hydrates and the mixtures of hydrates and quartz sands were … investigated by combustion experiments. The flame propagation, flame appearance, burning time and temperature in different hydrate … layers were studied. For pure propane hydrate combustion, the initial flame falls in the “premixed” category. The flame …

Spring harvested corn stover was used for direct combustion in a 146 kW dual chamber boiler designed for wood logs … combustion chamber at a rate of 10.5 to 12.8 kg/h over a 24-h period, with three replications, and compared to a control wood … combustion trial (12.1 kg/h during 24 h). The overall heat transfer efficiency for stover was lower than for wood (57% <em …

This paper presents a concise overview of ash deposition in combustion or co-firing of biomass (woody biomass … aspects on biomass combustion ash deposition are reviewed and discussed: influence of biomass fuel characteristics, deposit … technologies for reducing ash deposition and corrosion in biomass-involved combustion. …

The objective of this study was to observe the combustion process of extracted rapeseed (ER) grist in a stationary … combustion in the 90 to 200 kW (Kilowatt) SFB combustion test facility show that the optimal ER combustion temperature is within …

This paper presents a methodology to simulate the combustion of fixed beds of biomass particles using computational …

The present work focuses on the numerical modeling of combustion in liquid-propellant rocket engines. Pressure and …, combustion models and thermodynamic approaches were used for combustion modeling first in a trans-critical environment, then in …/Eulerian description. For modeling combustion, the Probability Density Function (PDF) equilibrium and flamelet approaches and the Eddy …
