This paper reports on analysis of 45 gasoline samples with different qualities, namely, octane number and chemical composition. Measurements of data from gas chromatography and IR (FTIR) spectroscopy are used to gasoline quality prediction and classification. The data were processed using...
This paper presents experimental results on co-firing of ‘as-received’ sugar cane bagasse and rice husk in a conical fluidized-bed combustor (FBC) using silica sand as the bed material. Axial temperature, O 2 , CO 2 , CO and NO concentration profiles in the conical FBC operated at 82.5–82.8...
Computational fluid dynamics is a widely used tool in optimizing natural gas burners, for instance, for emission issues. Especially, a further reduction of NO x emissions is of interest. However, due to computational efforts calculating three-dimensional turbulent flames, there is the necessity...
A mathematical model of a membrane reactor used for methane steam reforming was developed to simulate and compare the maximum yields and operating conditions in the reactor with that in a conventional fixed bed reactor. Results show that the membrane reactor resents higher methane conversion...
The combustion of coal in a mixture of pure O 2 and recycled flue gas is one variant of a novel combustion approach called oxy-fuel combustion. With the absence of N 2 , this approach leads to a flue gas stream highly enriched in CO 2 . For many applications, this flue gas stream can then be...
Particles emitted from three coal-fired power plants burning subbituminous coals from Alberta, Canada were examined for total particulate matter (PM) and size fractions PM >10 , PM 10 , and PM 2.5 . The sampling was carried out following EPA Method 201A, which requires a 6 inch port. Three tests...
The concept of fuel stratification has been proposed and applied to a four-valve port injection spark ignition engine. In this engine, two different fuels or fuel components are admitted through two separate inlet ports and stratified into two regions laterally by strong tumble flows. Each...
Prediction of ash fusion temperatures by using the chemical composition of the ash has previously been conducted only with linear correlations. In this study, a new technique is presented for predicting the fusibility temperatures of ash. Non-linear correlations are developed by using the...
