The scope of PSRU-JITE covers the research in Industrial Technology and Engineering, such as Computer Engineering, Logistics Engineering, Electrical Engineering, Mechanical Engineering, Civil Engineering, Electronic Engineering, Industrial and Production Engineering, Management Engineering, Science and Technology, Ceramic Innovation, Industrial Product Design, and Industrial Education. PSRU-JITE also covers all multidisciplinary research in Industrial Technology and Engineering and associated areas.</p> th-TH itepsru_journal@psru.ac.th (ผู้ช่วยศาสตราจารย์ ดร.สิริเดช กุลหิรัญบวร ) itepsru_journal@psru.ac.th (นางสาวอรณัชชา เบญจมาศ ) Mon, 27 Oct 2025 10:59:57 +0700 OJS 3.3.0.8 http://blogs.law.harvard.edu/tech/rss 60 https://ph02.tci-thaijo.org/index.php/psru-jite/article/view/261034 <p> The objective of this research was to develop a biomass briquette production system, including the design and installation of dust control equipment. The development was informed by a study on the health and environmental impacts of charcoal production and storage facilities, as reported by the Department of Health, Ministry of Public Health. Additionally, data on the biomass potential of agricultural residues suitable for renewable energy production were obtained from the Department of Alternative Energy Development and Efficiency (DEDE). Two types of agricultural residues available in Chonburi Province: rubberwood and eucalyptus wood residues were selected as raw materials. The produced charcoal briquettes were evaluated for their physical characteristics, moisture content, and heating value in accordance with the Community Product Standard (CPS) for Charcoal Briquettes. The developed production system consists of a crushing machine, a mixing unit, and a cold screw briquetting machine equipped with an automatic cutting unit. The system is powered by a 3-horsepower electric motor and includes electrical control components as well as dust suppression devices installed at the crusher and mixer. The quality of the briquettes was analyzed through Proximate Analysis following ASTM D7582, D5373, and D5865 standards. The results revealed that eucalyptus briquettes had a moisture content of 5.82% and a lower heating value (LHV) of 6,750 kcal/kg, while rubberwood briquettes had a moisture content of 5.71% and an LHV of 6,760 kcal/kg. All measured parameters complied with the relevant standards. The average combustion efficiency of the briquettes was 33.12% for eucalyptus and 33.73% for rubberwood. The developed production system effectively reduced charcoal dust dispersion and demonstrated strong potential for commercial application.</p> Korn Sitthiprapaporn, Kamonwan Jitjack, Srima Jakhom Copyright (c) 2025 PSRU Journal of Industrial Technology and Engineering https://ph02.tci-thaijo.org/index.php/psru-jite/article/view/261034 Mon, 27 Oct 2025 00:00:00 +0700
