 and included a pass-through into the roof for the flare stack and exhaust routing to feed through. The design also positioned an electrical panel enclosure in the rear of the enclosure to house the automation controls components.

The purpose of the hopper is to store the biomass used to operate the Powertainer. Its location is in the back half of the container and is open to the atmosphere from above, so operators are able to load easily the fuel from above. The hopper holds enough fuel for an eight-hour run during a high load (100– to 150-kW) application. The design of the hopper uses sheet metal in layers to allow hot air to flow into the fuel to enable final drying. The “spine” at the bottom of the hopper covering the drag chain components works as a fuel-metering device. Steel beams run across the top of the hopper to allow for a tarp or soft cover to protect fuel from weather events.

 * Internal feed rate. The internal feed system can sustain a fuel transfer rate to the gasifier of up to 4.28 kilograms/minute.
 * External feed rate. The external feed system can sustain a fuel transfer rate to the gasifier of up to 4.28 kilograms/minute.
