OPTIMIZATION OF COMBUSTION PROCESSES Facilitating Cost-effective and Environmentally Friendly Products

The combustion process poses significant challenges with respect to maximizing performance and fuel economy. The environmental impact of combustion by-products mandates a better understanding of the combustion process in order to secure a healthier society and planet Earth for present and future generations. Reduce Your Carbon Footprint Combustion is integral to many modern technological advances including automotive and aircraft engines, as well as the generation of electric power and heat. Given the limited availability of fossil fuels and their impact on the global climate, these...

Improving Fuel Economy The injection and distribution of fuel play key roles in the amount of energy released and the quantity of pollutants emitted from engines, gas turbines and burners. Optimizing and understanding fuel atomization, vaporization and mixing require advanced measurements to characterize technical alternatives. Dantec Dynamics’ dedicated diagnostic techniques let you obtain information such as spray shape parameters, fuel droplet size, velocity and temperature, as well as fuel concentration and mixing characteristics. Our systems are used worldwide in numerous research and...

Fuel Injection Lab, US Measuring Fuel Spray Temperature The air-fuel ratio is directly influenced by the spray droplet temperature and fuel vapor concentration in the combustion chamber. The new two-color Laser-Induced Fluorescence (LIF) technique can be applied to measure fuel spray temperature and provides data on the correlation between injection conditions and spray temperature for improvement of CFD models. spray atomization. It provides immediate feedback for the spray...

Achieving Cost-effective and Reliable Products Stability and efficiency of the combustion process are fundamental to reliable, cost-effective and environmentally friendly products. The key parameters to achieve this are ignition processes, flame stability, flame extinction and turbulent mixing. As shown in the selected examples, these parameters can be investigated with advanced laser-based techniques to obtain information about flow fields, intermediate combustion species, pollutant precursors and temperature fields. Reducing Fuel Consumption Local flame extinction in a combustion process...

Department of Mechanical and Aerospace Engineering, Case Western Reserve University, US Enhancing Coal Burner Efficiency Replacing Hydrocarbon Fuels with Hydrogen Coal burners require a design combining high combustion efficiency with low emissions. Optimizing the burners necessitates an understanding of both the flame dynamics at elevated pressures and their interaction with the flow field adjacent to the burners. Laser diagnostics, such as those provided by PIV, are necessary to measure the flame...

Reducing CO2 and Pollutant Emissions The need to reduce emissions of CO2, NOX and other pollutants from combustion processes is becoming increasingly important due to their impact on global warming and human health. In order to address these concerns, Dantec Dynamics provides diagnostic solutions to measure soot concentration, particle size, and concentration of unburned hydrocarbons. Methods for increasing the efficiency of exhaust gas after treatment strategies are also addressed. As illustrated below, application examples come from the industrial and academic sectors. Minimizing Soot in...

Lowering SOX, NOX and Particle Emissions from Power Plants Improving Power Plant Exhaust Gas Filtering The reduction of SOX, NOX and particulate emissions from coal-fired power plants is accomplished by scrubbers which are used to produce and distribute fine droplets as evenly as possible within the gas flow. Lechler GmbH develops and supplies spray nozzles for scrubbers, using PDA measurement solutions to measure droplet size and velocity, spray angle and pattern in order to optimize nozzle design. The filtration of exhaust gases from coal-fired power plants is essential for reducing their...
