Abstract In the present work, effect of forced air supply on combustion process liquid hydrocarbons was studied using diesel fuel as an example. The content flame intermediate components and temperature distribution along symmetry axis were atmospheric burner in which is atomized by a steam jet. gas composition equilibrium products heat release also investigated. influence excess ratio chamber ...

Micro burner is the fundamental element of a micro energy power system. The performance, output power, and efficiency system are directly involved by combustion stability, efficiency, temperature distribution exterior wall. Owing to small space resident short time premixed fuel/air, fuel difficult burn completely, resulting in poor burning flame stability. Therefore, study technology focus curr...

The CFD models JASMINE and SOFIE have been used to simulate the convection currents and thermal conditions inside one steel compartment due to a fire in an adjacent compartment. The impact, on the thermal environment inside the steel compartment, of the positioning of the adjacent fire in both 'side-heated' and 'bottom-heated' configurations has been examined. For the side-heated configuration,...

The methanol-burning lung model has been used as a technique for generating a predictable ratio of carbon dioxide production (VCO2) to oxygen consumption (VO2) or respiratory quotient (RQ). Although an accurate RQ can be generated, quantitatively predictable and adjustable VO2 and VCO2 cannot be generated. We describe a new burner device in which the combustion rate of methanol is always equal ...

An explicit equation leading to a method for improving furnace efficiency is presented. This equation is dimensionless and can be applied to furnaces of any size and fuel type for the purposes of comparison. The implications for current furnace design are discussed. Currently the technique most commonly used to reduce energy consumption in galvanizing furnaces is to increase burner turndown. Th...

A number of numer~cal simulations of rack storage fires have been carr~ed out, with various fuel types and burner outputs. Both the standard buoyancy-modified k E turbulence model and a recently developed turbulence model which significantly improves the consideration of the buoyancy effect on turbulence and turbulent transport, were used to study the turbulence of the buoyant flow. The flamele...

The article presents the results of researches development and field tests in bench conditions microdiffusion stabilizer burner device a rectangular slot type with niche deepening along entire perimeter burner. air passes through slot, gaseous fuel for combustion is supplied to recirculation zone system holes end wall stabilizer. On side output stabilizer, there deepening. As studies have shown...

The present study experimentally investigates fundamental characteristics of diffusion flames and the importance of gas radiation. In particular, transient measurements of flame growth, temperature, and radiation intensity of an expanding spherical diffusion flame in microgravity are used to investigate the effects of various diluents (N2, CO2) with different radiative properties. Two systems w...

In this multidisciplinary study a geared open rotor configuration is assessed and compared to an ultra high bypass ratio geared turbofan engine. Both designs assume a 2020 entry into service level of technology. The specific thrust level for minimizing block fuel and the resulting engine emissions for a given mission is sought. The tool used contains models that effectively capture: engine perf...

Document History This is the version of a gas burner that contains explicit timer events. In document OLD MS 7/1 a similar gasburner speciication without timers can be found. Document Purpose To show the Oldenburg part of a complete development (gas burner with timers)
