E-mail address: [email protected] Homogeneous charge compression ignition (HCCI) combustion mode has some benefits compared to the most popular conventional combustion forms used in the internal combustion (IC) engines: spark ignition (SI) and compression igni...

During the last decade extensive research has been made at Lund University, Sweden, on a lean premix (prevaporize) combustion concept with burnt gas recirculation and a metallic flame holder. From this concept a new lean premixed natural gas combustion chamber with internal combustion gas recirculation (CGR) has been developed for the V160/SOLO 161 Stirling engines. This combustor has ultra-low...

An experimental investigation of the combustion behavior of nano-aluminum (n-Al) and nano-aluminum oxide (n-Al2O3) particles stably suspended in biofuel (ethanol) as a secondary energy carrier was conducted. The heat of combustion (HoC) was studied using a modified static bomb calorimeter system. Combustion element composition and surface morphology were evaluated using a SEM/EDS system. N-Al a...

The need for flexible power generation is growing worldwide as the energy transition altering operational regimes of thermal plants. Plasma ignition systems, an alternative technology to conventional start-up method with natural gas or oil firing, offer a cost- and energy-efficient process in pulverized fuel stations. application plasma systems cold start-ups using different qualities pre-dried...

nanocrystalline complex oxides have been synthesized by combination of sol–gel auto combustion and ultrasonic irradiation techniques using copper nitrate, zinc nitrate as metallic nitrates and glycine, urea and thiourea as fuels. sol-gel combustion (combination of the chemical sol–gel process and the combustion process) as a proper synthesized technique is used to synthesize zno/cuo nanocomposi...

In this study, preheated crude sunflower oil at 75C was used in a fourcylinder, naturally aspirated, indirect injection diesel engine. The experiments were conducted at the constant engine speeds under the full load condition of the engine to determine the performance, combustion, and injection characteristics of test fuels. The engine test results have been compared with the reference values t...

Thermogravimetric analysis was used to examine the thermal behavior of dairy manure as a pyrolysis and combustion feedstock. Nitrogen and air were used as purging gases to analyze the pyrolysis and combustion reactions, respectively, and heating rates of 20 o C min -1 , 40 o C min -1 and 60 o C min -1 were applied. An Arrhenius model was used to estimate the kinetic parameters (activation energ...
