The solid residue from wood-based ethanol production has a low ash content and high heating value, making it interesting for combustion applications, e.g. small-scale appliances and gas turbines. Combustion and gasification properties have been studied using thermogravimetric analysis (TGA) and differential thermal analysis (DTA). Char combustion rate data obtained could be used in combustion s...

In this study, influence location bluff body in a non-premixed burner non-reactive field fuel and oxidizer is investigated numerically. Flow properties spatial mixing deficiency (SMD) are calculated evaluate actuator's reactants' inside burner. The res...

One strategy for reducing US dependence on petroleum is to develop new combustion technologies for burning the fuel-lean mixtures of hydrogen or hydrogen-rich syngas fuels obtained from the gasification of coal and biomass. Fuel-flexible combustion systems based on lean premixed combustion have the potential for dramatically reducing pollutant emissions in transportation systems, heat and stati...

The development of a liquid fueled mesoscale catalytic combustor is presented, based on the coupling of multiplexed electrosprays for liquid fuel dispersion and a stack of catalytic grids. The grids act as a compact catalytic reactor for combustion initiation, stabilization and enhanced conversion, as well as ground electrodes for the electrospray. The combustor has a volume on the order of few...

‡ The George Washington University, MS 335, NASA Langley Research Center, Hampton, VA, 23681. ABSTRACT The dual-pump coherent anti-Stokes Raman spectroscopy (CARS) method is used to measure temperature and the relative species densities of N2, O2 and H2 in two experiments. Average values and rootmean-square (RMS) deviations are determined. Mean temperature measurements in a furnace containing a...

3D numerical combustion simulation in a can burner fed with methane was carried out in order to evaluate pollutant emissions and the temperature field. As a case study, the General Electric Frame 6001B system was considered. The numerical investigation has been performed using the CFD code named ACE+ Multiphysics (by Esi-Group). The model was validated against the experimental data provided by ...

UNLABELLED A natural gas burner has been used as a precise and accurate source for generating large quantities of carbon dioxide (CO2) to evaluate emissions measurements at near-industrial scale. Two methods for determining carbon dioxide emissions from stationary sources are considered here: predicting emissions based on fuel consumption measurements-predicted emissions measurements, and direc...

The laminar smoke point properties of jet diffusion f lames-the luminous flame length, the residence time, and the fuel flow rate, at the onset of soot emission from the flames--have proven to be useful global measures of the soot properties of nonpremixed flames. These measures provide a means to rate several aspects of sooting properties: the relative tendency of various fuels to emit soot fr...
