Characterization of Reactivity Enhancement Coal Combustion with Empty Fruit Bunches Using Thermogravimetry Analysis [PDF]

E3S Web of Conferences, 2023
A study on the utilization of biomass in power plants as an alternative fuel was conducted. The benefit of biomass fuel is that it reduces greenhouse gas emissions, namely carbon dioxide, and contributes to reducing the effects of global warming.

Transient temperature measurement of unburned gas using optic heterodyne interferometry

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 2002
Optical heterodyne interferometry was validated to measure the transient temperature of a gas by comparing the temperature history of unburned gas in a combustion chamber, caused by compression due to flame propagation, obtained by the heterodyne interferometry with temperature obtained by assuming adiabatic change. When the density of gas changes, the

Asymptotic Analysis on High-temperature Premixed Flames: Instability of Flame Fronts under the Constant-enthalpy Conditions

Journal of Thermal Science and Technology, 2010
Asymptotic analysis on premixed flames with high-temperature combustible mixtures was performed to elucidate the instability of flame fronts. Planar premixed flames with sufficiently low Mach numbers were treated, and a one-step irreversible chemical ...

Effects of Flame Propagation Velocity and Turbulence Intensity on End-Gas Auto-Ignition in a Spark Ignition Gasoline Engine

Energies, 2020
Knocking is a destructive and abnormal combustion phenomenon that hinders modern spark ignition (SI) engine technologies. However, the in-depth mechanism of a single-factor influence on knocking has not been well studied.

Combustion analysis in a natural gas engine with pre-chamber by three-dimensional numerical simulation

Nihon Kikai Gakkai ronbunshu, 2015
Highly efficient natural gas engines have been widely used in wide range of sectors from industry and transportation. However, because combustion process in gas engines with a pre-chamber is very complicated, it is difficult to experimentally investigate

Modeling and Efficiency Optimization of Steam Boilers by Employing Neural Networks and Response-Surface Method (RSM)

Mathematics, 2019
Boiler efficiency is called to some extent of total thermal energy which can be recovered from the fuel. Boiler efficiency losses are due to four major factors: Dry gas flux, the latent heat of steam in the flue gas, the combustion loss or the loss of ...
