Design Specifications

The PP20 Power Pallet is made up of a GEK Hot TOTTI multi-stage gasifier, spark fired industrial engine, generator head, and electronic controller. The system automatically adjusts syngas/air mixture via a wide band Bosch oxygen sensor, shakes the grate when needed, and removes ash via a mechanical auger. The Process Control Unit (PCU) monitors and responds to all internal reactor, filter and engine conditions, and displays the results on an LCD screen. Power Pallet genheads are configurable to single, split or three phase, at 120/208/240 Vac, 60 Hz or 50 Hz, and are also available with an Optional Grid-Tie package allowing the PP20 to work with other power generating devices–such as wind or solar, as well as with additional Power Pallets, utilities or micro-grids–to generate reliable synchronized power. The product has a continuous power rating of 15 kW at 50 Hz, and 18 kW at 60 Hz. The sound level at 30 feet is 85 dB. The biomass consumption is 1.2 kg/kWh - 2.5 lbs/kWh. The run time per hopper fill (at 250 kg/m3 fuel density) is 10 hrs at 5 kW, 5 hrs at 10 kW, and 3 hrs at 15 kW. The maximum continuous operation time is over 12 hours, and the start-up time is 10-20 minutes. Operating conditions include an ambient temperature of 5-40 °C (40-100 °F), and humidity level of 5-95% RH. The installed footprint without the ash vessel or grid tie is 1.36 x 1.36 m (53.5 x 53.5 inches). In addition, the manufacturer suggests that the product be placed in a well-ventilated protected from rain and direct sun.

Product Schematics

Technical Support

Provided by the manufacturer.

Replacement Components

Replaceable components include gaskets, vessels, and tubing. Additional components can be made available upon request to All Power Labs.

Lifecycle

This product includes warranty at the manufacturer's discretion, with an expected lifetime of over six years with routine maintenance.

Manufacturer Specified Performance Parameters

Designer specified performance targets include: minimized component architecture, compact, improved tar conversion, fuel flexibility, and improved general efficiency.

Vetted Performance Status

Testing performed by researchers at Duke University attempted to model the dynamic performance of the PP20 Power Pallet by characterizing the fuel ratio, run time, etc. of the equipment, and creating a transfer function that captured the system performance. Overall, it was found that the system has approximately a 0.34 second time delay, a 0.10 second time constant, and a 600 second delay at PP20 startup. Other characteristics of the PP20 could not be defined given their significant dependence on environmental factors.

Safety

Potential hazards related to the operation of this product include exposure to flammable gases. Additional safety handles and warnings are included on the product.

Complementary Technical Systems

Complementary technical systems include the combined heat and power (CHP) module.

Academic Research and References

Compliance with regulations

The PP20 is ROHS compliant with the Plenum UL2043 Standard and is also Title 24 Compliant.

Evaluation methods

The manufacturer cites load testing for run time, sustained power output, and low threshold tests as evaluation methods. This product has not been specifically evaluated in the field with end-users (Interview with Representative).
