“…These models give relationship between the biomass HHV and the proximate analysis results (contents of moisture, volatile matter, fixed carbon, ash, and sulfur) or ultimate analysis (contents of C, H, O, N, S elements ) or results of both analysis respectively [11]. Ultimate analysis based models for HHV predicting were applied among others by Setyawati et al [12] for tropical peat and by Ozyuguran et al [9] for fruit juice pulps and fruit, vegetables and nut residues, stalk, stems etc. As far as proximate analysis based correlations are concerned Cordero et al [13] used it for HHV prediction of lignocellulosic and carbonaceous materials, whereas Özyuğuran and Yaman [3] applied it for different biomass sub-classes.…”

“…The design and operation of biomass combustion systems depend on such biomass characteristics as chemical composition, moisture content, ash amounts, and heating value [7,8]. Heating values of biomass, especially its higher heating value (HHV), belongs to the most important parameters that describes the fuel quality [9]. The HHV of a fuel evaluates the amount of heat released during combustion with the original and generated water that is in a condensed state.…”

The objectives of study were to investigate the ash content, carbon content and the higher heating value and modelling of HHV of forest and agricultural biomass. Five types of biomass were used for the experiments: sunflower husk pellets, wood pellets, straw and hay briquettes, and forest chips. The investigated biomass properties (their average values) change: for ash content between 1.3% (woods pellets) and 7.3% (hay briquettes), for carbon content between 37.4% (forest chips) and 52.0% (wood pellets), for HHV between 14.8 kJ/kg (forest chips) and 20.1 kJ/kg (sunflower husk pellets). Two mathematical models from literature and model proposed by the authors were used to the HHV calculation. The model proposed by the authors gave the best results in determination of sunflower husk pellets HHV.

“…The HHV of fuels can be determined experimentally by burning a specimen in a adiabatic oxygen bomb calorimeter under controlled conditions. The calorimeter measures the changes between reactants and products enthalpy [2,4]. The higher heating value can be also approximately predicted using empirical models.…”

The aim of the study was modelling of HHV of oat (grain and straw) biomass. The content of ash, carbon, hydrogen, nitrogen, moisture, volatile materials and the higher heating value of oat (grain and straw) biomass was measured. The possibility of using twenty models from the literature to describe HHV of oat was examined. The following models: HHV=19.914-0.2324A and HHV=-3.0368+0.2218VM+0.2601FC are recommended for determining of HHV of oat (RMSE of the range 0.13-0.28). The models based on ultimate analysis gave worse results in determination of HHV for oat.

The combustion chamber is one of the tools used to cultivate plantation, with fuel predetermined. Most people in rural areas the largest users of fossil fuels derived from kerosene, gasoline, petrol, LPG gas, coal and firewood. One agricultural wastes that can be utilized the candlenut shells capable of generating heat energy can help problems of crisis fossil fuel. Biomass fuel type castel space is one of main tools that can convert biomass into thermal energy can be harnessed to the needs of everyday people like cooking. The objective of this research is to know the energy of calor and fuel consumption that produced in combustion chamber of castel type biomass using fuel to hazelnut shell for patchouli oil distillation. This experimental method was conducted experimentally, with the main materials and equipment of combustion chamber biomass type, boiler, boiler water pipe, condenser, centrifugal blower, hazelnut shell, patchouli leaf. The working procedure is started from the combustion process inside the combustion chamber to heat the water in the boiler until distillation process to occur between dried patchouli leaves with water vapor. Then it is cooled from the coil type separator so that the vapor mixture turns phase to water mixture with patchouli oil, then the mixture is separated in the oil phase separator glass by water so that it is obtained pure patchouli oil. The results show that the combustion chamber type that is made have been in accordance with existing theoretical standards. Where the results of testing and data analysis recommend the feasibility to be applied to the patchouli oil industry. In the candlenut shell fuel of obtained heat energy of Qf = 9.356.59 k.cal/hr with a temperature of 795 °C, while the higher heating value of 18.446 kJ/kg and lower heating value at 17.170 kJ/kg. The conclusion of this research is that besides can get good distillation technology, also can utilize existing fuel around the residence and not yet utilized in this case biomass of candlenut shell which have high calorific value for burning process in the combustion chamber.
