Sawdust / EFB Briquette and Sawdust Charcoal Briquette Process Technology


Published on

Sawdust / Empty Fruit Bunch Briquette and Sawdust Charcoal Briquette Process Technology. Indonesia and Malaysia have abundant resources of EFB of palm oil mill waste that potential to briquette. Then sawdust is also abundant in many places in Indonesia that potential to briquette (uncarbonised briquette) and sawdust charcoal briquette (carbonised briquette).

Sawdust / EFB Briquette and Sawdust Charcoal Briquette Process Technology

  1. 1. Production Process of Sawdust Briquette, EFB Briquette, & Sawdust Charcoal BriquetteSawdust Charcoal Briquette Eko SB Setyawan
  2. 2. Sawdust Briquette EFB (Empty Fruit Bunch) Briquette Overview Briquette Sawdust Charcoal Briquette EFB (Empty Fruit Bunch) Briquette
  3. 3. Overview Briquette • Densified products can be found as briquettes or as Pellet • The heating value, moisture content and chemical characteristics are about the same for briquettes and pellets. • Some application of sawdust/EFB briquette• Some application of sawdust/EFB briquette (uncarbonised briquette) can be found • Carbonised briquette is sawdust charcoal briquette. Higher fixed carbon means higher heating value.
  4. 4. Overview Briquette • An increased bulk density (from 200kg/m3 for sawdust to 1000-1400kg/m3 after densification), resulting in lower transportation costs, reduced storage volume and easier handling. • A lower moisture content (MC <10%), allowing a longer shelf life and minor losses of product during the storage period. • An increased energy density and more homogeneous composition, resulting in better combustion control possibilities and thereby higher energy efficiency during combustion. • Relatively high-energy cost for the briquetting process, increasing the price of the end product.
  5. 5. Overview Briquette • If the product exceeds 25 mm in diameter, it is called a briquette. • The small size for pellets makes them easy to be used in fully automatic operations, from household appliances to large-scale combined heat and power (CHP) plants.
  6. 6. Overview Briquette • Comparison between Ram/Piston dan Screw extruder briquette
  7. 7. Overview Briquette Tipe Screw Extruder Briquette Tipe Ram/Piston Briquette
  8. 8. Overview Briquette • Comparison screw press briquette, piston press briquette & pellet fuel
  9. 9. Overview Briquette • Standard Sawdust Briquette atau EFB Briquette mengacu ke : European Standard (CEN); Swedish Standards Institute, SIS-CEN/TS 14961:2005; DIN 51731; Austria ÖNORM M7135 • Sawdust from hard or soft wood, before and after extrusion (briquetting):

  11. 11. Esensi Proses Pembuatan Sawdust Briquette, EFB Briquette & Sawdust Charcoal Briquette Briquetting is compaction of biomass (biomass densification) so as to facilitate handling utilization, saving transportation costs and ease of storage. Part of the outer shell briquette partially carbonized making Sawdust briquette & Sawdust Charcoal Briquette briquette partially carbonized making it easier ignition, combustion and protect from moisture environment. Hole in the centre also make better air circulation for combustion. Sawdust briquetting will produce sawdust briquette then can be followed by carbonization to produce sawdust charcoal briquette.
  12. 12. Process Variables • Types of Raw Materials • The Size of Raw Materials • Moisture Content • Hardness • Density • The Size of Product • Product specification• Product specification • Ash Content • Single or mixed material? • Raw material chemistry • Ash chemistry • Impurity • Die Specification • Operational of the Screw Press These variables have tended to make briquetting and its carbonisation more of an “art” than a “science”, through significant strides are being made in the sophistication of this process, bringing these variables under more control.

  17. 17. Arrangement of Cellulose, Hemicellulose and Lignin in Biomass
  18. 18. Gluing characteristics in Sawdust Briquette & EFB Briquette Production Biomass densification such briquette with high pressure / compression will increase the mechanical interlocking and adhesion between particles, thus forming bonds between theforming bonds between the molecules in the contact area. On biomass raw materials such as wood can be divided into the mechanism of adhesion and cohesion adhesion force, the attraction between the particles and interlocking bonds.

  20. 20. Sawdust Briquette • Calorific value, moisture content, ash content, ash chemistry and dimension are the sawdust briquette parameters of quality. • General specification : L=490 mm; d=55 mm; w=1,1 kg
  21. 21. EFB Briquette • EFB Briquette can be used just like sawdust briquette. • Can be made from 100% empty fruit bunches of palm oil or mixed with sawdust.sawdust. • Analysis of the quality of products such as table below:
  22. 22. Sawdust Charcoal Briquette High calorific value (>7500 kcal / kg) were comparable to the high fixed carbon (~ 90%), low moisture content (<3%), low ash content, and specific dimensions of sawdust charcoal briquette is a quality parameter. Selection of the good raw material of sawdust that will determine the final product quality.

  27. 27. Market of Sawdust / EFB BriquetteMarket of Sawdust / EFB Briquette • Sawdust / EFB Briquette can be used for home appliances such as space heating or for industry up to electricity generation.generation. • Characteristics of Sawdust / EFB briquette will determine the technology of utilization such as combustion, gasification or pyrolysis.
  28. 28. Market of Sawdust Charcoal BriquetteMarket of Sawdust Charcoal Briquette • Sawdust charcoal briquette mainly used exclusively for BBQ or burning food. So sawdust briquette charcoal when burned should not smoke and do not damage the flavor of food.
  29. 29. Problem SolvingProblem Solving A. Export Palm Kernel Shell (PKS) in BulkA. Export Palm Kernel Shell (PKS) in Bulk Export palm kernel shell in bulk form is done so far, resulted in inefficient due to high transportation costs. Palm shell briquetting will increase to 2-fold density (600 kg/m3 shell -> 1200 kg/m3 briquettes), so it becomes a solution. Biomass agri- waste can be used for fluidised bed combustion for electricity production.

The renewable portfolio standard (RPS) to start in 2012 states that 2% of purchased electricity shall come from renewable energy sources at the start of the scheme. The percentage of required renewable energy will increase incrementally to reach 10% by 2022.
