In developing countries, more than 1.5 million deaths are caused per year by air pollution resulting from the use of wood, dung, coal, and other traditional fuels used for household energy that is used by approximately 3 billion of the world's population. The unsustainable use of wood for fuel has negative impacts on both the local and global environment. Biogas technology, which produces methane...
A laboratory scale updraft fixed bed gasifier was designed to study the characteristics of gasification and incineration of organic solid wastes. Research had been carried out on the emission characteristics of SO2, NO and NO2 of solid wastes in the gasifier in different operation condition, the effects of reactor temperatures (650degC-790degC), gasification mediums (air and oxygen) and the flow rate...
This paper analyzed chemical and physical properties of diesel fuel and biodiesel. The influence of B20, B50, B100 and 0# diesel fuel mixture on diesel engine performance has been studied in a HF495Q3 engine. Test results show that the driving force of the engine is weaker with the adding of methanol, miximum power, miximum torque reduced about 9.8%, 5.6%; For better evaluated engine economic, in...
Based on time-varying statistical data and emission factors, multiyear NMVOCs emission inventories from fossil fuel combustion, biofuel burning, and biomass open burning in China for 1980-2005 were presented by a bottom-up estimate. The contributions of fossil fuel, biofuel, and open burning are estimated as 35%, 50%, and 15%, respectively, in 2005. Spatial distribution of NMVOCs emission shows that...
This paper presents modeling and simulation of microturbine (MT) models to analyze its load following performance as distributed energy resource (DER) with general as well as critical priority loads. Two different models of MT were considered for performance analysis. The first model consists of speed governor, acceleration control, and temperature control blocks while the other is GAST model of MT...
