Indirect Dryer Systems

The indirect dryer unit has been designed with the decades of experience of handling biomass feedstocks from the previousthermal treatment projects that the IQ Energy team worked on. The indirect dryer unit slowly dries out the dewatered wasteinput continuously moving it across serpentine belts with heat applied indirectly (the heat not contacting the product). Thisprocess significantly reduces the weight and volume of the waste input and dries it to a valuable product for agriculture,industry or as an input to the thermal treatment process. The indirect dryer unit typically takes a dewatered waste input of~80-85% moisture content and dries this down to an easy to handle ~15-20%moisture content.

Heat Recovery

IQ Energy’s Indirect Dryer Unit can effectively use various heat sources for the drying process.This can include:

  • Current onsite heat sources, like a cogeneration exhaust, flue gas or other onsite heat.
  • Diesel or gas burners
  • IQ Energy’s Carbonisation Units.

Unit Examples

Commercial G500 – Alberta

  • Successfully operated on piggery manure.
  • Moving to a commercial site in 2024 where it will process pulp sludge, biosolids & animal wastes, as well as other biomass and mixed feedstocks.
  • Will supply dried feedstock (15-20% moisture content) to the IQ Energy carbonisation unit.
