Calorific Value of Gaseous Fuels

Methane number testing of alternative gaseous fuels

Alternative gaseous fuels, like syn-gas and bio-gas, are attractive fuels for internal combustion engines due to energy and environmental concerns. Although the worldwide use of alternative gaseous fuels has increased, the knock properties of these fuels are not well understood. The methane number (MN) knock rating technique was selected based on its range and sensitivity. Eight alternative gas...

Fast estimation of the calorific values of forest fuels by near-infrared reflectance spectroscopy

Fuel calorific value is an important parameter in fire behaviour. The objective of this study is to evaluate the potential of using near-infrared reflectance spectroscopy (NIRS) for determining the calorific value of fuel. Fifty samples of various fuel components from the Mediterranean forest (17.1–24.6 MJ⋅kg–1) were used to establish a calibration equation between NIR spectra (1100–2500 nm) an...

Coal Calorific Value Prediction Based on Projection Pursuit Principle

The calorific value of coal is an important factor for the economic operation of coal-fired power plant. However, calorific value is tremendous difference between the different coal, and even if coal is from the same mine. Restricted by the coal market, most of coal fired power plants can not burn the designedcoal by now in China. The properties of coal as received are changing so frequently th...

A Review on Steam Coal Analysis -Calorific Value

investigation of the flame temperature for some gaseous fuels using artificial neural network

in the present study the adiabatic temperature of gaseous fuels were calculated and the influence of effective parameters of flame temperature was discussed. firstly, a new computational program named ftc (flame temperature calculations) was prepared to calculate the adiabatic flame temperature and then the effect of initial temperatures of combustion air and fuel, excess air content and oxygen...
