  • Management process S130 In the management process S130, the delivery date of the biomass delivered to the stockyard 20 is managed. In the management process S130, by managing the delivery date of the biomass delivered to the stockyard 20, it becomes possible to manage the freshness of the biomass.
  • the delivery date may be, for example, the date on which the biomass is removed from the site where the biomass is generated.
  • the delivery date may be, for example, the date on which the biomass (EFB) is discharged from the oil palm oil mill 10.
  • the biomass fuel production system 100 according to this embodiment is provided near the oil palm oil mill 10. Therefore, it does not take a long time to transport the biomass from the oil palm oil mill 10 to the stockyard 20. Therefore, the delivery date generally coincides with the date on which the biomass is discharged from the oil palm oil mill 10.
  • the freshness of the biomass discharged from the oil palm oil mill 10 is generally constant. Therefore, by adopting the date on which the biomass is discharged from the oil palm oil mill 10 as the delivery date, the freshness of the biomass can be managed with high accuracy.
  • management process S130 is performed, for example, by the above-mentioned management device 110.
  • biomass from the stockyard 20 in the discharge step S140, for example, it is preferable to discharge biomass from the stockyard 20 within four days of the date of delivery, more preferably within three days of the date of delivery, and even more preferably within two days of the date of delivery. This allows juice to be squeezed out from the biomass more efficiently in the squeezing step S160. Note that biomass within four days of the date of delivery can also be said to be biomass that has been stored in the stockyard 20 for four days or less.
  • the dispensing process S140 is performed, for example, by the dispensing device 120 described above.
  • Primary cutting process S150 In the primary cutting step S150, the biomass discharged in the discharging step S140 is primarily cut.
  • the primary cutting step S150 is performed by, for example, the primary cutting device 130 described above.
  • compression step S160 In the squeezing step S160, the biomass discharged in the discharging step S140 and primarily cut in the primary cutting step S150 is squeezed to remove the squeezed juice (extract) from the biomass. This makes it possible to reduce the ash concentration remaining in the biomass after the second dehydration step S200 described below to a target value at low cost.
  • the target value is the upper limit of the ash concentration required in a furnace that burns biomass fuel.
  • the target value is, for example, 2000 ppm.
  • the squeezing step S160 is carried out, for example, by the squeezing device 140 described above.
  • the method for producing biomass fuel according to this embodiment does not include a heating step of heating the biomass before performing the squeezing step S160.
  • the biomass is not heated from the time it is brought into the stockyard 20 until the squeezing step S160 is performed. Note that this heating is performed using either or both of electrical energy and combustion energy, and does not include the heating of the biomass caused by sunlight while it is stored in the stockyard 20. This makes it possible to reduce unnecessary energy for heating.
  • the moisture content of the biomass to be squeezed is, for example, 50% by mass or more and 80% by mass or less. If the moisture content of the biomass to be squeezed is less than 50% by mass, the freshness is low, and the amount of juice squeezed out of the biomass is small. In that case, even if the subsequent steps from the first washing step S170 to the second dehydration step S200 are performed, the concentration of ash remaining in the biomass cannot be reduced to the target value. Furthermore, due to the nature of biomass, the moisture content of the biomass will not exceed 80% by mass. Therefore, by setting the moisture content of the biomass to be squeezed to 50% by mass or more and 80% by mass or less, the juice can be squeezed out of the biomass more efficiently in the squeezing step S160.
  • the compression force when squeezing the biomass is, for example, 30 MPa or more and 60 MPa or less. If the compression force when squeezing the biomass is less than 30 MPa, the degree of destruction of the biomass tissue is low, and the amount of juice squeezed out from the biomass is small. In that case, even if the subsequent steps from the first washing step S170 to the second dehydration step S200 are performed, the concentration of ash remaining in the biomass cannot be reduced to the target value. On the other hand, if the compression force when squeezing the biomass exceeds 60 MPa, the equipment cost of the squeezing device 140 increases.
  • the tissue of the biomass can be efficiently destroyed, and the concentration of ash remaining in the biomass after the second dehydration step S200 can be reduced to the target value at low cost.
  • First cleaning step S170 In the first washing step S170, the biomass compressed in the compressing step S160 is washed with water, thereby allowing the ash remaining in the biomass to be dissolved into the water.
  • the first cleaning step S170 is performed, for example, by the first cleaning device 150 described above.
  • the bubbling section 154 bubbles gas when the biomass is washed with water. This makes it possible to loosen and agitate the biomass with the bubbled gas. This makes it possible to promote the dissolution (dissolution) of ash contained in the biomass into the water. Therefore, it is possible to further remove ash compared to the conventional technology in which the biomass is washed with only water without bubbling.
  • the bubbling unit 154 preferably bubbles the combustion exhaust gas after drying the biomass in the drying device 190.
  • the combustion exhaust gas has a higher carbon dioxide (CO 2 ) content than air. Therefore, the more the combustion exhaust gas is bubbled, the more the pH of the water used to wash the biomass can be lowered to 7 or less (for example, about pH 5 to pH 6).
  • the water used to wash the biomass can be made acidic. The more acidic the washing water becomes, the more the amount of ash eluted increases, so by bubbling the combustion exhaust gas, it is possible to efficiently remove ash from the biomass.
  • one technique for lowering the pH of the water being washed is to add chemicals such as nitric acid or sulfuric acid.
  • adding chemicals will result in extra nitrogen and sulfur components being added to the biomass (biomass fuel) after washing. When these are burned, nitrogen oxides (NOx) and sulfur oxides (SOx) are produced, so adding chemicals should be avoided as much as possible.
  • the bubbling unit 154 bubbles gas containing carbon dioxide, such as combustion exhaust gas, to lower the pH of the water used to wash the biomass. This makes it possible for the bubbling unit 154 to avoid the generation of air pollutants such as nitrogen oxides and sulfur oxides even when the biomass fuel produced from the washed biomass is burned. It also makes it possible to reduce the cost of chemicals.
  • carbon dioxide such as combustion exhaust gas
  • the combustion exhaust gas after drying the biomass is at a temperature higher than room temperature (e.g., 25°C). Therefore, by bubbling the combustion exhaust gas with the bubbling section 154, the temperature of the water can be made higher than room temperature.
  • room temperature e.g. 25°C. Therefore, by bubbling the combustion exhaust gas with the bubbling section 154, the temperature of the water can be made higher than room temperature. The higher the temperature of the water used for washing, the faster the ash dissolves, making it possible to efficiently remove ash from the biomass.
  • First dehydration step S180 In the first dehydration step S180, the biomass washed in the first washing step S170 is squeezed to dehydrate the biomass, thereby making it possible to further reduce the concentration of ash remaining in the biomass.
  • the first dehydration step S180 is performed, for example, by the first dehydration device 160 described above.
  • the compression force when squeezing the biomass is, for example, 30 MPa or more and 60 MPa or less. If the compression force when squeezing the biomass is less than 30 MPa, the amount of waste liquid squeezed out from the biomass is small, and even if the subsequent second washing step S190 and second dehydration step S200 are performed, the concentration of ash remaining in the biomass cannot be reduced to the target value. On the other hand, if the compression force when squeezing the biomass exceeds 60 MPa, the equipment cost of the first dehydration device 160 increases.
  • the second cleaning step S190 is performed, for example, by the second cleaning device 170 described above.
  • the bubbling section 174 bubbles gas when the biomass is washed with water. Therefore, similar to the first cleaning step S170 described above, it is possible to promote the dissolution of ash contained in the biomass into the water. Also, similar to the bubbling section 154 described above, it is preferable that the bubbling section 174 bubbles the combustion exhaust gas after the biomass is dried in the drying device 190. This makes it possible to lower the pH of the water used to wash the biomass to 7 or less. Therefore, it is possible to remove ash from the biomass more efficiently.
  • the second dehydration process S200 is performed, for example, by the second dehydration device 180 described above.
  • the compression force when squeezing the biomass is, for example, 30 MPa or more and 60 MPa or less.

On the other hand, if the compression force when squeezing the biomass exceeds 60 MPa, the equipment cost of the second dehydration device 180 increases.
