Evaluasi Prediksi Nilai Higher Heating Value (HHV) Biomassa Berdasarkan Analisis Ultimate [PDF]

Jurnal Jejaring Matematika dan Sains, 2019
Biomassa merupakan energi terbarukan yang sangat penting, dimana keberadaannya dapat menggantikan bahan bakar fosil baik padat maupun cair. Sebagai bahan bakar tentu perlu adanya analisis-analisis untuk mengetahui karakteristik dan kualitas biomassa sehingga kita dapat mengklasifikasikan biomassa yang potensial digunakan sebagai bahan bakar.

A Novel Method for the Estimation of Higher Heating Value of Municipal Solid Wastes

Energies, 2022
The measurement of the higher heating value (HHV) of municipal solid wastes (MSWs) plays a key role in the disposal process, especially via thermochemical approaches. An optimized multi-variate grey model (OBGM (1, N)) is introduced to forecast the MSWs’

Modeling the Higher Heating Value of Spanish Biomass via Neural Networks and Analytical Equations

Energies
Accurate estimation of biomass higher heating value (HHV) is crucial for designing efficient bioenergy systems. In this study, we developed a Backpropagation artificial neural network (ANN) that predicts HHV from routine proximate/ultimate composition ...

Determination of higher heating values (HHVs) of biomass fuels

, 2012
Current 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 ...

Multitechnique Physicochemical Characterization of Horse Hoof Trimmings as Sustainable and Untapped Keratin Source. [PDF]

ChemistryOpen
Horse hoof trimmings, cruelty‐free and traceable keratin‐rich waste, were characterized for particle size, morphology, thermal stability, composition and metal contamination. Results show a high higher‐heating value and promising upcycling paths for energy and materials, but variable metal contamination (shoeing‐ and milling‐dependent) requires ...

Prediction of HHV (Higher Heating Value) of Different Biomass Samples

The primary indicator of the fuel value of a biomass sample is its heating value. Based on the chemical and elemental composition results, it is possible to calculate the approximate calorific value of any fuel using the appropriate formulas. The aim
