Abstract:
1. A process for energy recovery and transfer, the process comprising: warming fresh air in a heat recovery and pressure control unit; feeding waste feed and the warm fresh air into a processor; reducing a moisture content of the waste feed by providing the waste feed between rotating blade assemblies of the processor to break the waste feed into a fuel powder in the warm fresh air, at least one of the blade assemblies including a plurality of blades being supported by a first shaft and another of the blade assemblies including a plurality of blades supported by a second shaft, the first and second shafts being substantially parallel and offset from one another; filtering contaminated air through an initial filter to remove the fuel powder from the contaminated air; pre-heating the contaminated air in the heat recovery and pressure control unit using contained heat exchange; raising the temperature of the pre-heated contaminated air in a chamber through fuel combustion; passing chamber discharge air from the chamber to an expansion box; passing the chamber discharge air from the expansion box to the heat recovery and pressure control unit; passing the chamber discharge air through the heat recovery and pressure control unit using contained heat exchange to pre-heat contaminated air passing on to the chamber and to warm fresh air passing on to the processor by lowering the temperature of the chamber discharge air; filtering terminal air through a terminal filter to remove particles from the terminal air, wherein a proportioning valve is adjustable to control the pressure of the chamber discharge air in the heat recovery and pressure control unit; and controlling the distribution and pressure of the chamber discharge air in the heat recovery and pressure control unit with a proportioning valve in a conduit, the proportioning valve being controlled based on at least the fresh air temperature and/or the contaminated air temperature.
