A cost–effective backward Lagrangian method for simulation of pollutant formation in gas turbine combustors by post–processing of complex 3D calculations
A backward Lagrangian Monte Carlo modelling is proposed to calculate by post–processing the PDF of the thermo–chemical parameters of complex turbulent reactive flows simulated with a simple turbulent combustion model. PDF's of minor species such as pollutant species (NOx, soot, unburnt hydrocarbons...) can be easily obtained as long as these species have no significant influence on the main ...

Detailed chemical modelling of a flameless combustion turbine for pollution prevention
Flameless combustion has been acknowledged as one of the most interesting combustion technologies to meet both the targets of high process efficiency and low pollutant emissions. The present investigation is concerned with the application of the flameless combustion mode to an adiabatic combustor, typically used in gas turbine engines. Detailed chemical kinetics calculations, by means of a ...

Reducing air pollution from electricity-generating large combustion plants in the European Union
Background In 2008, the European Environment Agency (EEA) published a first assessment of the theoretical potential to reduce emissions of nitrogen oxides (NOX) and sulphur dioxide (SO2) from electricitygenerating large combustion plants (LCPs) (EEA, 2008). That earlier study showed that improving the environmental performance of existing LCPs by applying best available techniques potentially ...

An integrated assessment for wind energy in Lake Michigan coastal counties
The benefits and challenges of onshore and offshore wind energy development were assessed for a four‐county area of coastal Michigan. Economic, social, environmental, and spatial dimensions were considered. The coastal counties have suitable wind resources for energy development which could contribute toward Michigan's ten percent renewable energy standard. Wind energy is cost‐effective with ...

First discernments for NO storage and reduction on lithium cuprate at moderate temperatures
Heriberto Pfeiffer works at the Instituto de Investigaciones en Materiales from the Universidad Nacional Autónoma de México at Mexico city. His research interests are focused on different topics as: i) the CO2 capture and catalytic conversion to added product values; ii) the sorption and reduction/oxidation of other acid polluted compounds (CO and NOx); iii) the hydrogen production ...

Performance of the low-emission flare
Job report / Elbisgraben (Bale / Switzerland) The summer of 1992 had finally arrived. The 5MW low emission furnace in the district heating station Liestal was ignited, supplied with landfill gas from Elbisgraben landfill. Since then the plant has been running continuously and the comprehensive measurements taken, verify that all targets aimed at have been achieved: plant efficiency 90%, low ...

Energy Security
Renewable & Clean Energy Solutions to Secure Energy Independence from Foreign Oil. FOREIGN OIL: As imports grow and world prices rise, the amount of money we send to foreign nations every year is soaring. At current oil prices, we will send $700 billion dollars out of the country this year alone — that’s four times the annual cost of the Iraq war. Projected over the next 10 ...
