Dimethyl ether (DME) is considered a promising alternative to diesel fuel in compression-ignition engines because of low particulate and NOx emissions along with high thermal efficiencies as well as improved auto-ignition characteristics due to its high cetane number. Recently, DME also has been selected as a prospective fuel candidate for the validation of turbulent combustion models organized...

The linear response to harmonic acoustic excitation of the total heat release rate in technically premixed flames (Flame Transfer Function, FTF) is studied case an ideal swirl burner. analysis based on linearization production for mean reaction progress variable modelled with a turbulent flame speed closure. Three main components FTF are identified which generated by: I) direct fluctuations fue...

This paper experimentally investigates the effects of cross wind on flame interaction and burning characteristics double liquid pool fires. Two burners were used including a square burner line burner. The separation distance between fires speed varied, providing total 66 test conditions. experimental results showed that mass rate increases initially with increasing until critical value, after w...

This paper is devoted to the analysis of effect gas injection on efficiency gaseous fuel burning. A coaxial burner with a perforated inner wall presented in which methane–air acceleration observed. With use numerical analysis, it demonstrated that flame related flow separation from that, turn, leads reduction heat losses as well vortex formation and momentum losses. On basis obtained results, n...

To investigate the ignition characteristics of an axial-flow injection burner for a Stirling engine, combustion chamber was designed. Diesel used as fuel and oxygen oxidant. The experiments were carried out with electric plug igniter. under different pressure, pre-oxygen supply time, flow position studied. experimental results show that, increase time increases gradually, success rate decreases...

There is a rapid increase in the demand for low NOx hydrogen/methane combustion systems recent years, and emission burners furnaces are promising platforms such applications. Combustion instability most important drawback uniform thermal field. This paper investigates influence of CO2 methane hydrogen on instability. Numerical simulations were conducted using small swirl burner furnace system. ...

This paper discusses optimal control strategies for switching between different burner modes in a novel compact marine boiler design. The ideal behaviour is defined in a performance index the minimisation of which defines an ideal trade-off between deviations in boiler pressure and water level from their respective setpoints and the cost of burner switches and variation of continuous input flow...

Energy savings in Diesel Power Plants (PLTD) have been carried out by comparing the Marine Fuel Oil (MFO) processing process when using a burner/thermal tank and an electric heater. are analyzed this study calculating comparison of operational costs, cost efficiency time. The place research was one Indonesia, with object being heater tank. method used quantitative methods form literature study,...

In recent years, the gas turbine power plant has been increasingly used in various industries Kazakhstan. The reasons for this are: thermal efficiency; simplicity of scheme and design; small mass per unit; high maneuverability; low toxicity; relatively simple automation operation. This paper presents experimental study results a two-tier air burner as part engine combustion chamber at burning l...
