Onsite Biomass Gassification Powerplants
Power for the Next Century
Phoenix Energy designs and builds small scale (.5 to 2 MW) gasification powerplants fueled by biomass (wood waste, agricultural waste, or other biological waste products). By diverting more waste out of landfills, Phoenix Energy not only helps save money but it also helps to save further environmental damage.
Phoenix Energy biomass gasification power plants are seamlessly integrated with the electrical grid. This means that when you produce more power than you need, you can sell your excess power to the local utility. Similarly, when you need more power than you are generating, you can supplement by taking part of the power from your Phoenix Energy power plant, and part from the power company.
Phoenix Energy biomass gasification powerplants have a tight footprint, needing just 1250 square feet of space. Additionally, the engine can be housed separately and the entire unit is self contained, minimizing the impact on your land.
How it Works
Phoenix Energy’s model PHX-1000 converts wood into a synthetic natural gas (“syngas” or “producer gas”) through the process of gasification. This syngas is then used to fuel a specially modified natural gas genset to produce electricity and heat.
In a process very similar to manufacturing charcoal, the gasification process partially combusts wood in an oxygen starved environment. By depriving the fire of sufficient oxygen the wood does not burn, but rather gives off a flammable gas. As the wood gives off the syngas, it is transformed into biochar. The syngas is then captured, cleaned and cooled before being sent as fuel to the genset which converts the syngas into electricity.
|Normally, but not always, our systems begin with a grinder. That grinder mashes up the biomass fuel which can include things like wood chips, orchard waste, forestry slosh and thinnings. The grinder processes cut ends, culled lumber, scrap and other wood waste into a consistent size. It also removes metal from the waste stream (binding straps, soda cans, etc.) The fuel is then fed into a storage hopper by means of a belt conveyor or elevator to the top of the gasification chamber. There the fuel is dropped through an airlock into the chamber. The fuel gets dried, heated, pyrolysed, partially oxidized and reduced in this reactor as it flows through it. After the syngas has been extracted from the gasifier it is cooled and cleaned by a series of scrubbers and filters. We use sawdust and wood chips as filter media so instead of using expensive synthetic filters that need to be thrown away, the used filter media are simply placed into the fuel hopper and consumed, improving efficiency, reducing cost, and virtually eliminating negative environmental impact. Once the syngas is cooled and extracted, it is then run through a standard Caterpillar generator to create electricity. This electricity is then fed to the power grid.
Our normal proposal for electricity generation is based on natural gas gensets. Our systems are modular and can be set up for a variety of power needs, 50 or 60 Hz, 3 phase, 1000 kW (1mw). If more power is needed, our units can be stacked in a modular format allowing for addition power in increments of 100 kW.
