Torrefaction can reduce the mass of wood by up to 30% (dry mass basis), resulting in a denser, higher-valued product that can be transported more economically than wood chips. With Heyl Patterson’s torrefaction equipment, wood retains up to 90% of its energy value. This energy-dense end-product can be used as a replacement for coal or co-fired with coal in electric power plants. This manmade coal can provide energy rates of up to 23.7 million BTU per ton. Natural coal generally provides 28.4 million BTU per ton. Download the white paper.

The increasing sophistication and cost of dryers used for bulk solids handling operations make dryer maintenance very complex, which can affect your operation’s profit. Much of a maintenance program’s effectiveness stems from keeping an accurate maintenance record and using that record for planning. That planning entails recording a dryer’s performance and normal operating conditions, and scheduling dryer inspections and regular preventive maintenance. The following paper discusses elements that should be part of a dryer’s maintenance record, with information on how to use each element when maintaining the dryer, as well as how to use the record when deciding whether to repair, rebuild or replace an older dryer.

  • What to Include in a Maintenance Record
  • How to Use Each Element When Maintaining a Dryer
  • Deciding When to Repair, Rebuild or Replace Older Dryers
