Density Equation of Cassava-Stalk Briquettes Under Moderate Die-Pressure
American Journal of Applied Sciences 7 (5): 698-701, 2010 ISSN 1546-9239 © 2010Science Publications Density Equation of Cassava-Stalk Briquettes Under Moderate Die-Pressure Patomsok Wilaipon Department Mechanical Engineering, Faculty Engineering, Naresuan University, Phitsanulok, Thailand 65000 Abstract: Problem statement: Agricultural residues seem to be the most promising energy resources for developing countries. However, the majority of them have low energy density. One of the favorable technologies for enhancing that property is briquetting. For the case of Phitsanulok, a province in Northern Thailand, cassava is one of the most important crops. Therefore, a large amount of cassava stalk is left in the field after harvest. This study was aimed to investigate the quantity of cassava stalk in this province and to study cassava stalk briquette production. Approach: The potential energy from cassava stalk was calculated based on the productivity, residue-to-product ratio, residue returned to soil ratio and its heating value. Besides, the effects of moderate-range compression pressure, 70-110 bar, and the binder ratio, 10-20%, on briquette density were investigated. An empirical model was also developed and validated. Results: Base on the estimation, the quantity of usable cassava stalk in this area was approximately 18 kton year−1. The heating value of cassava stalk was found to be 16.39 MJ kg−1. Therefore, the total energy over 289 TJ year−1 can be obtained from this agricultural waste. According to the experiment, briquette density was in the range of 0.40-0.77 g cm−3. The coefficient of multiple determination for prediction of the proposed model was about 94.7%. -

E-mail: [email protected] ABSTRACT Fusarium wilt disease (FWD) is caused by the soil-borne fungus Fusarium oxysporum f. sp. cubense (Foc) and results in severe devastation of global commercial banana production. Foc-resistant banana genotypes show promise for sustainable effective control of FWD. ScaU1001 and ScaS0901 markers and their putative banana cultivars were evaluated for FWD resistance under greenhouse conditions after artificial infection by Foc race 1 (Foc1). The Foc1 genotype was characterized from six Fusarium fungi isolated from the pseudostem of banana cv. ‘Kluai Namwa’ (ABB genome) using specific primer (Foc1), resulting in two Foc isolates (PL3 and PL6) with an expected 354 bp PCR product. Both ScaU1001 and ScaS0901 markers were amplified as a unique PCR product (1694 bp and 1429 bp, respectively) in two banana cultivars ‘Kluai Khai Kasetsart 2’ (AA genome) and ‘Kluai Hom Khiew’ (AAA genome), indicating that both cultivars probably carried a Foc-resistant DNA fragment. -

The Project for Flood Countermeasures for Thailand Agricultural Sector in the Kingdom of Thailand Final Report
Japan International Cooperation Agency Ministry of Agriculture and Cooperatives THE PROJECT FOR FLOOD COUNTERMEASURES FOR THAILAND AGRICULTURAL SECTOR IN THE KINGDOM OF THAILAND FINAL REPORT Appendix II: Technical Papers July 2013 SANYU CONSULTANTS INC. NIPPON KOEI CO., LTD. RD JR 13-074 Preface and Acknowledgement “The Project for Flood Countermeasures for Thailand Agricultural Sector” is a part of a comprehensive assistance program from the Japan International Cooperation Agency (JICA) to the Royal Thai Government concerning the damage sustained in Thailand, during the 2011 flood. Serious damage was caused to the business and agricultural sectors in the Chao Phraya River Basin. The JICA assisted in emergency response by dispatching portable pump units, experts on disaster management and goods and supplies, for both medium and long-term support. It was identified that the preparation of an Integrated Flood Mitigation Plan needed to be undertaken. To support the Thai agriculture and rural sector, the JICA dispatched a preliminary study mission in early 2012, following this it was decided to conduct the main Project from March 2012 up until July 2013. This Project consisted of the three components, i.e. 1) support for the reproduction of pastures, 2) rehabilitation and reinforcement of damaged irrigation/drainage facilities, and 3) a guideline for disaster-resilient agriculture and agricultural community. This paper is one of a series of technical papers, relating to component number three (3), “Guideline for Disaster-Resilient Agriculture and Agricultural Community”, which consists of a general guideline and five thematic guidelines for five sectors. In the process to formulate the guideline, seven Tambons and a District were selected from five provinces, namely Phitsanulok, Chainat, Ayutthaya, Pathumthani and Nakhon Pathom, as the model areas for research and activities to be conducted. -

Density Equation of Bio-Coal Briquettes and Quantity of Maize Cob in Phitsanulok, Thailand
American Journal of Applied Sciences 5 (12): 1808-1811, 2008 ISSN 1546-9239 © 2008 Science Publications Density Equation of Bio-Coal Briquettes and Quantity of Maize Cob in Phitsanulok, Thailand Patomsok Wilaipon Department of Mechanical Engineering, Engineering Faculty, Biomass Energy Research Unit, Naresuan University, Phitsanulok, Thailand 65000 Abstract: One of the most important crops in Phitsanulok, a province in Northern Thailand, is maize. Base on the calculation, the quantity of maize cob produced in this region was approximately 220 kton year−1. The net heating value of maize cob was found to be 14.2 MJ kg−1. Therefore, the total energy over 874 TJ year−1 can be obtained from this agricultural waste. In the experiments, maize cob was utilized as the major ingredient for producing biomass-coal briquettes. The maize cob was treated with sodium hydroxide solution before mixing with coal fine. The ratios of coal:maize were 1:2 and 1:3, respectively. The range of briquetting pressures was from 4-8 MPa. The result showed that the density was strongly affected by both parameters. Finally, the relationship between biomass ratio, briquetting pressures and briquette density was developed and validated by using regression technique. Key words: Biomass binder, maize cob binder, coal briquette, biomass-coal briquette INTRODUCTION handling characteristics are improved. Therefore, it is crucial that this fine material should be economically Biomass, particularly agricultural residues, seems compacted into the regular shape and size. Several to be one of the most promising energy resources for researches about coal-briquette production have been developing countries. The idea of utilizing the residues carried out.
