The Full Solution: PP30 Power Pallet

The Power Pallet is a complete biomass power generation solution that converts dense biomass like wood chips and nut shells into electricity and heat. It is a compact, integrated system – from biomass in, to power out.

The Power Pallet is comprised of the 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, displaying the results on an LCD screen. The PP30 also comes standard with Grid/Paralleling and Combined Heat and Power (CHP) systems for very high-efficiency operation.

Power Pallet genheads are configurable to single, split or three phase, at 120/208/240Vac, 60hz or 50hz.

Combined Heat and Power (CHP)

Our Combined Heat and Power (CHP) system more than doubling the Power Pallet’s total system efficiency by adding the thermal output to the electrical output. APL’s CHP System uses a flat plate heat exchanger (HX) to capture heat from the engine’s cooling system in stage one, a second stage with a custom-built HX capturing heat from the syngas, and a third stage exhaust HX.

This is possible because only 20% of the energy contained in the feedstock is able to be converted to electricity by our genset. Most of the other 80% is normally lost via heat in the engine’s cooling system and exhaust. By recovering some of this heat, the CHP allows 80% total efficiency for the whole system by delivering up to 50 kW of thermal energy in addition to the 25 kW of electrical energy. This heat can be pumped via the working fluid to other locations where it can used for radiant floor heating and numerous other processes.

Optional Accessory: Continuous Feed Airlock

To eliminate manual refilling of the hopper, ALL Power Labs is now offering a Continuous Feed Airlock as an option on all Power Pallets. Controlled by an Electronic Control Unit (ECU) with an array of sensors, this system allows a store of feedstock at ground level to be automatically fed, via a standard agricultural feed transport (not included), into the hopper through an automated gate valve on the hopper lid. The horizontal motion of the linear drive operating the gate valve is converted into a vertical sealing force by an innovative leaf spring system, ensuring an airtight seal and reliable operation.

The custom ECU, using an open-source processor with an APL-designed circuit board, reads data from sensors installed in the hopper and opens the gate valve when the feedstock is low, then signals the motorized feed transport to reload the hopper. Once it detects the hopper is full, the ECU shuts off the feed transport then closes the gate valve. This smart automation also reads gate position and motor-current sensors to assure safe operation for both operators and the Power Pallet. If problems are detected, the ECU will set the Continuous Feed system into various safe and stable modes and trigger alarms to alert the operator.

Powertainer PT150

The ALL Power Labs 150kW Powertainer is a compact and cost-optimized biomass power generation system, enclosed within a standard 20’ shipping container. The system is fully automated and complete: from biomass hopper, gasifier and gas filtering, to engine, generator and electrical output control – all within the shipping container envelope. The goal is a total-system-in-a box, drop it off the truck and go – no onsite construction required.

The Powertainer was originally developed as part of a US Dept of Energy project with the University of Minnesota, Morris, Cummins Power, and the Diesel Research Lab of U of Minnesota, Twin Cities. On January 23, 2015, All Power Labs received a $2M USD grant from the California Energy Commission to begin work on commercializing the Powertainer. Along with project partners UC Berkeley, Sierra Pacific Industries, and the Placer County Air Pollution Control District, APL will be working to make a modular power plant able to convert forest fire remediation waste into on-demand clean energy. Pricing has yet to be determined.
