In laboratory experiments, we investigated the ability of two task/ambient conditioning systems with air supplied from desk-mounted air outlets to efficiently ventilate the breathing zone of heated manikins seated at desks. In most experiments, the task conditioning systems provided 100% outside air while a conventional ventilation system provided additional space cooling but no outside air. Ai...
Dilution of the intake air of the SI engine with the inert gases is one of the emission control techniques like exhaust gas recirculation, water injection into combustion chamber and cyclic variability, without scarifying power output and/or thermal efficiency (TE). This paper investigates the effects of using argon (Ar) gas to mitigate the spark ignition engine intake air to enhance the perfor...
–Fast depletion of fossil fuels demands an urgent need to carryout research to find viable alternative fuels such as Hydrogen, LPG and CNG. The gaseous hydrocarbons seem to be best immediate option presently available[1]. The remarkable feature of gaseous fuels are the absence of mineral impurities, the consistency in quality and the convenience and efficient in use. LPG is used widely as a co-...
In the current stage over 85% of world energy demand is supplied by fossil fuels. Coal-fired plants discharged roughly 40% of the total CO2 are the main contributors in CO2 emissions (Kim & Kim, 2004; Yang et al., 2008). Environmental issues caused by exhaust green house gases (GHG) and toxics have become global problems. Through the past studies of five decades, increased GHG levels in atmosph...
This paper presents an experimental investigation on a four-stroke single cylinder diesel engine fuelled with the blends of Mahua oil methyl ester (MOME) and diesel. The performance emission, energy, and exergy analysis has been carried out in B20 (mixture of 80% diesel by volume with 20% MOME). From energy analysis, it was observed that the fuel energy input as well as energy carried away by e...
Emission of volatile organic compounds (VOCs) produced during composting of different organic wastes (source-selected organic fraction of municipal solid wastes (OFMSW), raw sludge (RS) and anaerobically digested wastewater sludge (ADS) and animal by-products (AP)) and its subsequent biofiltration have been studied. Composting was performed in a laboratory scale composting plant (30l) and the e...
The temperature of exhaust gases from simple cycle gas turbine generation sets (GENSETs) is usually very high (around 500 C), and a heat recovery steam generator (HRSG) is often used to recover the energy from the exhaust gases and generate steam. The generated steams can be either used for many useful processes (heating, drying, separation etc.) or used back in the power generation system for ...
Hyperspectral imaging (HSI) device users often require both high spectral resolution, on the order of 1 nm, and high light-gathering power. A wide entrance slit assures reasonable étendue but degrades spectral resolution. Spectrometers built using High Throughput Virtual SlitTM (HTVS) technology optimize both parameters simultaneously. Two remote sensing use cases that require high spectral res...
This paper presents an approach to the suppression of the emission of dioxin and its precursors as a result of the co-incineration of poly (vinyl chloride) (PVC) with TiO2-encapsulating polystyrene (TEPS), in which TiO2 nanoparticles with the capacity to adsorb dioxin and its precursors are encapsulated without significant agglomeration. Field-emission scanning electron microscopy (FE-SEM) and ...
abstract the goal of this research is simulating an optimum reactor to eliminate greenhouse gases, mainly co2, through combined cycle in stacks of power plant, using a strong base (sodium hydroxide) thinned by water. during this process sodium bicarbonate salt is generated together with water and the produced salty water is desalinated and its useful salts are also extracted. four scenarios hav...
