PDI burner chambers are custom designed for every fuel type to ensure that they are versatile enough to accommodate the full range of fuel moistures experienced on site. Burner fuel can range from 5% to 60% moisture in our single units.
Custom designed ductwork in a PDI Energy System ensures that only hot gas at the amount required makes it over to the dryer system.
PDI burners are also supplied capable of burning 3” or less fuel. It is normal for our clients to screen the fuel only to remove very large chunks of fuel, and avoid using a hog or chipper. PDI offers fuel systems complete with cleaning screens, enabling the proper fuel feed into the burner.
The burners are equipped with full abort systems to provide a fail-safe operation during power outages and startup.
PDI burner systems are often equipped with secondary recycle gas loops, allowing for precise temperature control on the outlet. The furnace is fired based on total load on the system, and capable of providing a consistent outlet temperature, regardless of the firing rate.
These versatile units can burn dry or wet fuel or any combination, and still produce heat capacities from 1 to 60 MM BTU/hr.
PDI burners utilize a customized air-to-fuel ratio, allowing the burner to handle a full range of moisture without generating blue haze, CO, or Nox.
With high heat capacities for a single unit, the PDI Energy System provides an economic and versatile unit capable of burning virtually any typical wood waste stream as fuel. With the addition of our burner, the savings in screenings that can be turned into finished product is typically over 10% of the plant production.
