A self-sustained porous burner without a sprayed atomizer was built for diesel oil. It consisted of metal fiber felt as an evaporator upstream and ceramic foam emitter downstream. The liquid fuel underwent film boiling in the rapidly evaporated by heat recirculated from to through intense irradiative flux. effect structure its installation location on performance investigated. results indicated...

The aim of this experimental study is to investigate the combustion low-calorific producer gas within porous burner. small scale downdraft biomass gasification for rural area was performed produce gaseous fuel. Three types wood in Thailand were used as raw materials gas, i.e. Acacia-mangium, White popinac and Eucalyptus. low heating values range 3800-4232 kJ.kg-1 that are difficult burn convent...

Characteristics of microjet hydrogen diffusion flames stabilized near extinction are investigated numerically. Two-dimensional simulations carried out using a detailed reaction mechanism. The effect burner wall material, thickness, and thermal radiation on flame characteristics such as height maximum temperature studied. Results show that the stabilizes at lower fuel jet velocities for quartz t...

A two-step numerical concept was developed for modelling combustion and predicting nitrogen oxide emissions. The model validated by the Sandia flame D experiment with measurement data from burners on industrial furnaces. In this paper, implemented to evaluate influence of hydrogen blending natural gas up 40 vol.% an burner oxidizer temperatures at 300 K 813 assess performance without altering p...

The goal of this work is to investigate the feasibility of a hybrid solid oxide fuel cell (SOFC) and gas turbine (GT) system for mobile power production. A system consisting of a gas turbine, a burner, and an SOFC is examined to gain fundamental understanding of the system dynamics. A control oriented dynamic model is developed to provide the critically needed tool for system feasibility analys...

In this paper the layout of pilot plant (100 kg/h) for the supercritical water gasification (SCWG) of biomass is proposed. The proposed layout involves a reactor, units to separate water and hydrogen, a burner and several heat exchangers. This scheme was also simulated by means of the commercial software Aspen Plus (Aspen Tech, Inc.) in order to state the influence of different parameters such ...

Few-layer graphene is grown on copper and nickel substrates at high rates using a novel flame synthesis method in open-atmosphere environments. Transmittance and resistance properties of the transferred films are similar to those grown by other methods, but the concentration of oxygen, as assessed by X-ray photoelectron spectroscopy, is actually less than that for graphene grown by chemical vap...

Fire whirls cause an increase in fire damage. This study clarified the unsteady behavior of whirls, considering that instantaneous changes temperature and flame shape can affect damage to surrounding area. Numerical simulations a lab-scale simulates whirl were performed investigate gas velocity fields under various fuel inflow velocities. The flow field was obtained by solving continuity equati...
