Relationships Proximate Analysis Results and Higher Heating Values of Lignites
Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2008Abstract In this study, the higher heating values (HHVs) of 26 lignite samples were calculated by using the proximate and elemental analyses data. The proximate analysis results such as volatile materials (VM), fixed carbon (FC) and HHV and the elemental analysis results such as carbon (C), hydrogen (H), oxygen (O), nitrogen (N) and sulfur (S) were ...

COMBUSTION PROPERTIES AND CALCULATION HIGHER HEATING VALUES OF DIESEL FUELS
Petroleum Science and Technology, 1998ABSTRACT Physical, chemical, and fuel properties of diesel fuel samples were investigated in the research. Combustion heats as higher heating values (HHV) of the samples were determined experimentally and calculated from ultimate analysis data. The HHV (MJ kg−1) of the samples as a function of carbon (C, wt%) and hydrogen (H, wt%) was calculated from ...

Calculation of higher heating values of hydrocarbon compounds and fatty acids
Petroleum Science and Technology, 2018ABSTRACTHydrocarbon compounds are formed by carbon and hydrogen elements. The higher heating values (HHVs) of the hydrocarbon compounds can be calculated based on the carbon (C) and hydrogen (H) contents of the chemical structures. HHVs (MJ / kg) as a function of the carbon (C) and hydrogen (H) fractions of N-saturated hydrocarbons can be calculated by

Multiple regression and genetic programming for coal higher heating value estimation
International Journal of Green Energy, 2018The higher heating value (HHV) is an important characteristic for the determination of fuels quality. Nevertheless, its experimental measurement requires intricate technologies. In this work, the HHV of coal was predicted from ultimate composition using two methods: multiple regression and genetic programming.

Prediction of Higher Heating Value of Raw Materials and Biochar
Chemistry & Chemical TechnologyOne of the most essential characteristics of biochar (charcoal) is its higher heating value. The higher heating value for the dry ashless state of 35 samples of raw vegetable materials and charcoal was determined to establish the dependencies between the quality of the raw material and the produced biochar samples.

Determination of higher heating values (HHVs) of biomass fuels
2012Current issues related to fuels can be grouped under four headings. Today world is facing three critical problems: (1) high fuel prices, (2) climatic changes, (3) air pollution, and [4] heating value. Higher Heating Value (HHV) is one of the most important properties of fuels which explain the higher energy content and determine the efficient use of ...
