The use of new and renewable energy for the application on gas burners is beneficial environment. This study aims to determine effect excess air during combustion producer from biomass gasification release heat used as a fuel burner. Simulations are carried out by applying mass balance, showing that an increase in will decrease non-adiabatic adiabatic flame temperature. result showed reduces am...

Electricity industries worldwide have been restructured in order to introduce competition.As a result, decisionmakers are exposed to volatile electricity prices, which are positively correlated with those of natural gas in markets with price-setting gas-fired power plants. Consequently, gas-fired plants are said to enjoy a “natural hedge.” We explore the properties of such a built-in hedge for ...

The secreted cysteine proteinase SpeB is an important virulence factor of group A streptococci (GAS), whereby SpeB activity varies widely among strains. To establish the degree to which SpeB activity correlates with disease, GAS organisms were recovered from patients with pharyngitis, impetigo, invasive disease or acute rheumatic fever (ARF), and selected for analysis using rigorous sampling cr...

Pollutant emissions from combustion systems are a major area of concern with today’s energy needs. Numerical simulations have helped with the design of clean and efficient combustion strategies over the years. However, with the emergence of new fuels and combustion modes, it is necessary to improve the computational models. In this research, improved NOx and soot models are developed which uses...

Biomass is the oldest form of energy used by human beings, mainly in the form of wood. It is a renewable source of energy and has many advantages from an ecological point of view. The direct combustion of biomass generates concern among environmentalists, as it is incomplete and inconsistent and may produce organic particulate matter, carbon monoxide and other organic gases. Biomass gasificatio...
