Analysis of Fuel Properties for Peat: A Case Study Mohammad Tofayal Ahmed, Yasir Hasan, Shamiul Islam, Mominur Rahman ... Gaseous, liquid, and solid fuels; chemical and the fossil fuels are the major part not only our country but also the world energy market and these are considered the main supply of thermal energy. An important factor for peat accumulation is the chemical and structural composition of the organic material, which determines its “ability to decay.” However, water seems to be the most important external factor limiting decay. INTRODUCTION Peat is a type of soft soil with high content of fibrous organic matters. chemical properties of peat from four land management conditions undrained and drained forest, degraded (land, and managed agricultural land). PHYSICAL AND CHEMICAL PROPERTIES OF FRACTIONATED PEAT. Therefore, it is important to understand the physical, chemical and geotechnical properties of the peat. Because peat has high organic content and high natural water content, it is potentially problematic for civil engineering projects involving construction on peatland. The transformation of peat organic matter by chemical, biochemical and As the peat fibre contains a high amount Physico-chemical properties of peat in particular surface-active, sorption and ion exchanges, defining their biological function, depend mainly on the chemical composition and molecular structure of humic substances representing the major constituent of organic soil (peat). Acta Hortic. The aim of the study reported here was to investigate the properties of two Iranian peat … chemical and mechanical properties of peat fibres as well as flammability of peat-based knitted fabrics were analysed. Peat can also be defined as the accumulation of 100% pure organic material which contains at least 65% organic matter or less than 35% mineral content (Muhamad et al., 2010). behavior of peat and lead to loss of wetability caused by drying (Kwak et al., 1986). Key words: Peat, humification, physical properties, chemical properties. The structure, origin and fate of such molecular configurations are thus clearly linked to the water-retention properties of peat (Sokołowska et al., 2005). Peat chemical properties In general, approximately 80–90% of a fresh peat sample is composed of water and the remaining of solid material. The reserves of Prasad, M. and Maher, M.J. (1993). The aim of … The properties examined included thermal analysis (by T G A and DSC), IR spectroscopy and the zero point o f charge From D S C analysis it was found that the ignition point for the peat materials occurred at about 200°C. Therefore, it is important to understand the physical, chemical and geotechnical properties of the peat. The average diameter of the peat fibres is ~60 µm, but it varies in very wide ranges – 25–150 µm; however, the number of fibres with diameter more than 100 µm is very low. Peat was sampled from depths of 10–15 cm, 40–45 cm, 80–85 cm and 110–115 cm then partitioned into woody (Ø >1.5 mm), fibric (Ø 0.15–1.5 mm) and amorphic (Ø < 0.15 mm) Abstract. Peat accumulation generally takes place as a result of limited decay (decomposition) of plant material. 342, 257-264 DOI: 10.17660/ActaHortic.1993.342.29 The solid material has most of the components as organic and only 2–10% as inorganic.
