Sago Bark

 Much research has been done on the determination of the heating value of biomass waste, but currently no research is being done on the heating value of sago bark. In Malaysia, sago bark is an abundant waste product from sago starch extraction. This study presents the moisture content and heating value determination of paddy straw, empty fruit bunch (EFB), sago bark, oil palm kernel shell (OPKS), and wood chips. The moisture content and heating value of the investigated biomass were determined according to the British Standard EN 1477-2:2009 and bomb calorimeter, accordingly. It was observed that paddy straw recorded the highest moisture content at 97.75% wt. This was followed by EFB 95.34% wt., sago bark 96.05% wt., OPKS 95.28% wt. and wood chips 11.61% wt. In the dry state, wood chips had the highest heating value, with a value recorded as approximately 22.41 MJ kg-1, followed by OPKS 21.40 MJ kg-1, sago bark 19.56 MJ kg-1, EFB 17.82 MJ kg-1 and paddy straw 15.33 MJ kg-1. Current experimental trials suggest that the heating value of sago bark makes it suitable for use for co-firing with coal power generation.

Rice husk is biomass that can be utilized as fuel for biomass gasification as a renewable energy source. In this paper, thermochemical methods were used to determine the higher heating values, moisture content, bulk density, pellet density, microstructure, and elemental composition of Thai Rice Husk (Oryza Sativa Linn). The heating energy was analyzed using a bomb calorimeter, which showed a higher heating value of 15.46 MJ/kg. Determination of pellet density through rice husk powder pelletization exhibited a value of 1.028 g/cm3, while moisture content was 5.017 wt%. The heating value and moisture content revealed good agreement with the literature values, indicating the potentiality of rice hush for energy generation. Scanning electron microscopy (SEM) showed that the raw rice husk and its ash have similar porosity types but different bulk structure.  Elemental analysis using energy dispersive X-ray (EDX) indicated that rice husk contains O, Si, C while O and C percentages were drastically decreased during combustion. The obtained heating value and moisture content proved that rice husk could be used as a bio-energy source in biomass gasification for power generation.

This work deals with determination of heating value by wood chips of waste cane of seven varieties of grape wine. The results show, that the highest values of heating power has variety Portugais Bleu (16,64 MJ . kg−1) and MOPR (16,39 MJ . kg−1). The wood chips from this varieties were at the same time with lowest values of all water volume (12,71 %–4,59 %). Opposite the lowest values of heating power were by varieties Saint Laurent (15,93 MJ . kg−1) and Petit Riesling (16,10 MJ . kg−1) with all water volume 49,09 % and 41,97 %. By the help of laboratory measurement, calculations and statistic evaluation of results was not show the influence of different varienties on funds of heating value.

The purpose of the study was to determine the influence of the steam explosion process on the change in properties of the material subjected to this process. Wood chips were used before and after the steam explosion (SE), and pellets made from wood chips subjected to steam explosions (black pellet). The scope of the study included determination of physical and chemical characteristics such as moisture content, combustion heat and calorific value, determination of lignin and hemicellulose, cellulose and hydrogen, carbon, nitrogen and sulfur content. hemicellulose compounds. After the process biomass, there are still mainly cellulose and lignin compounds that are readily biodegradable. The process results in a slight increase in material humidity and lower calorific value, but further processing in the form of agglomeration results in reversal of these effects.

Subsequent Heating

An engineering approach for the calculation of the specific mass energy consumption, which is needed for defrosting and the subsequent heating of the frozen wood chips above the hydroscopic range, (in kWh·t-1), has been suggested. Equations for easy calculation of have been derived, depending on the wood moisture content u, on the fiber saturation points of the wood species at 20 °C and at –2 °C (i.e. at 293.15 K and at 271.15 K), and respectively, on the initial chips’ temperature, T0 , and on the final temperature of the heated after their defrosting chips, T1.For the calculation of the according to the suggested approach and equations a software program has been prepared in MS Excel 2010. With the help of the program calculations have been carried out for the determination of the energy consumption , which is needed for defrosting and subsequent heating of oak, acacia, beech, and poplar frozen chips with moisture content in the range from u = 0.4 kg·kg-1 to u = 1.0 kg·kg-1, initial temperature t0 = –20 °C and t0 = –10 °C until reaching of the chips‘ mass temperature of t1 = 80 °C, t1 = 100 °C, and t1 = 120 °C at the end of the heating.
