Particulate Matter and Ammonia Emission Factors
Emissions rates for particulate matter less than 10 m (PM10) and ammonia (NH3) from commercial tunnel–ventilated broiler houses in central Texas were analyzed using linear regressions to develop emission rates as a function of bird weight for broilers on litter. Interior ambient temperature and relative humidity were not found to be significant factors affecting emissions. From the regression e...
متن کاملParticulate Emission from Internal Combustion Engines
In this work, number concentration and size distribution at the exhaust of a Port Fuel Injection (PFI) Spark Ignition (SI) engine downstream a three-way catalyst and a Direct Injection Common Rail Diesel engine have been measured with two particle size instruments. The gas exhaust is first diluted, a nano DMA is used to obtain the particles size distribution function in the 3-60 nm range, in pa...
متن کاملParticulate Matter Emission Factors for Biomass Combustion
Emission factor is a relative measure and can be used to estimate emissions from multiple sources of air pollution. For this reason, data from literature on particulate matter emission factors from different types of biomass were evaluated in this paper. Initially, the main sources of particles were described, as well as relevant concepts associated with particle measurements. In addition, arti...
متن کاملA Preliminary Particulate Matter Emission Factor from Cotton Harvesting
Particulate matter (PM) sampling of cotton harvesting operations at three locations in Texas was conducted during the summer of 2006. PM emissions generated by a two-row (John Deere model 9910) and six-row (John Deere model 9996) cotton picker were measured at each sampling location. The PM emissions from the two-row and sixrow machines were measured using a protocol employing collocated low vo...
متن کاملCharacterising Acoustic Emission Signals for the Online Monitoring of a Fluid Magnetic Abrasives Finishing Process
To implement an automated fluid magnetic abrasive (FMA) finishing process, an online monitoring scheme is proposed based on characterising acoustic emission (AE) signals in this paper. According to the material removal mechanisms during the FMA finishing process, the AE generation and characteristics are predicted analytically to be dominated by the interactions between the surface asperities a...
