CEBCON PELLET COOLER WITH HEAT RECOVERY

Outstanding energy efficiency, flexible design and increased fire safety: CEBCON has developed an innovative, internationally patent-pending pellet cooler featuring an energy-efficient heat recovery system for use in the pellet production process.

CEBCON has developed an innovative and internationally patent-pending pellet cooler that features an energy-efficient heat recovery system for use in pellet production. Depending on the selected design, the cooler can process granules from a variety of biomass. This includes pellets made from:

  • By-products from the forestry and timber industry, sawdust, logs
  • Agricultural waste such as straw, shells, husks
  • Solid fermentation residues from biogas production
  • Whole plants such as bamboo, miscanthus, wood from short-rotation plantations.


In addition to its heat recovery, the cooler is characterised by considerable electricity savings of 45-70% as well as by fewer wearing parts than conventional pellet coolers. The cooler can be implemented either as an integrated component for new pellet production facilities or as a stand-alone module to replace existing facilities. 

The innovative CEBCON pellet cooler improves energy efficiency in pellet production, increases operational safety and achieves significant cost reduction. In addition, thanks to its special design as a containerised cooler, it increases flexibility: This facilitates transport and assembly, while reducing the amount of space required. The newly developed pellet cooler is a shaft cooler, the walls of which consist of heat exchanger plates. Due to the special arrangement of these cooling elements, the wood pellets or other solid, bulk biofuels are cooled particularly effectively and gently, in particular avoiding dust formation and large quantities of exhaust air. 

ADVANTAGES OVER CONVENTIONAL COOLERS:

  • Special design features of the cooler enable very energy-efficient operation compared to conventional coolers, while nevertheless achieving the same cooling capacity and throughput.
  • The recovered heat of 91 kWh or approx. 600 MWh/a (assuming 6,500 production hours per year and a press capacity of 4 to/hour) can be used for drying and conditioning the raw material before pressing.
  • The electricity consumption of the cooler is around 45-70% lower than that of the comparable systems. For a conservatively calculated number of production hours of 6,500 h/a and a press capacity of 4 to/h, the electricity savings amount to approximately 11.6 kWh or 75 MWh/a. 
  • This enables a significant reduction of energy costs during production, resulting in savings of around EUR 23,000 per year (depending on the electricity and heat prices at the location in question). Unlike conventional systems, the cooler pays for itself quickly due to the above-mentioned energy savings.
  • Maintenance costs are also reduced due to the design features. It was possible to dispense with bag filters and large blowers, while using simpler components. Because of the few moving parts, the wear and the risk of failure, as well as the operating expenses (lubrication, etc.) are low. 
  • In addition, the cooler is safer to operate as a result of the avoidance or minimisation of explosion and fire risks during cooling. The risk of fire is negligible compared to counter-stream coolers.
  • And finally, the pellet cooler is flexible and easy to use: It is equipped with necessary temperature and level sensors as well as control technology and can be integrated into the upstream plant control system for automated operation. In addition, the cooler is designed in standard container format, which reduces the transport and installation costs. Pre-assembly and testing are carried out at the factory before delivery to the customer: These result in a shorter assembly time (by up to 80%) and accelerated commissioning.

 

COOLING CAPACITY: 

  • Depending on the chosen design, the plant has a cooling capacity of 2-5 to. pellets/h.
