The Effects of Moderate Die Pressure on Maize Cob Briquettes

This case study explores the impact of moderate die pressure on maize cob briquettes in Phitsanulok, Thailand, using biomass as an alternative fuel. The study focuses on the briquetting technology, including the use of molasses, pressure levels, dwell time, and moisture content. Results include data on relaxation in length, volume, impact resistance index, weight loss percentage, water resistance, elongation percentage, and increased volume with varying die pressures.

  2. PHOTOSYNTHESIS PROCESS BIOMASS AS A FUEL Biomass: alternative fuel

  3. Phitsanulok Province Located in lower part of Northern Thailand Approximate Area: 10,896 km2 Population: 846,630 Major Product: Rice, Maize, Cassava, Banana

  4. Maize in Phisanulok Approximately 103,116 acre/year has been devoted for maize plantation The productivity is over 140,000 ton/year.

  5. Maize Cob in Phisanulok Residual to Product Ratio 0.273

  6. Maize Cob in Phisanulok Approximate 38,801 tons available in this area

  7. BRIQUETTING TECHNOLOGY

  8. Molasses 23% by weight 38mm ID x 100mm H 100 g of material: 73% maize cob and 23% molasses Pressure: 7, 10 and 13 MPa Dwell time: 15 seconds Moisture content: 7.5%
