Published by Elsevier Ltd.The aim of the research is to develop correlation equation to predict HHV of tropical peat based on its ultimate analysis. The Eijkelkamp peat sampler was employed to take samples of peat in five different districts in Pontianak, Indonesia. Samples were taken up to 2 m depth with 50 cm increments therefore total 20 samples were obtained. Ultimate analyses and higher heating value (HHV) of peat were evaluated in order to predict HHV based on its ultimate analyses results. It was found that C, H, O, S, N and ash contents in dry bases (in weight %) had ranges of 15.63 – 59.43%, 2.63 – 6.47%, 13.35 – 36.84%, 0.12 – 3.86%, 0.48 – 2.01% and 1.00 – 64.05%, respectively. HHV had ranges of 8.07 – 21.69 MJ/kg. Based on chemical composition of dry peat therefore new equation formulae to predict HHV peat was HHV = 17.830 + 1.508 H + 0.102 N + 0.575 S – 0.192 O-0.205 Ash, with an average absolute error and bias error of 2.18% and 0.17%, respectively.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Ash contents,Average absolute error,Chemical compositions,Correlation equation,High heating values,Higher heating value,Pontianak,Ultimate analysis[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]High heating value,Pontianak,Prediction,Tropical peat,Ultimate analysis[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1016/j.proeng.2015.11.048[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
