== Design Criteria ==
The gasifier should be designed in such a way that it can satisfy a specific set of use cases. These use cases should consider the availability of three products produced by the gasification process, namely Heat, Ash or char and combustible gases.

Use of excess heat:
*heat air in a shelter
*dry fuel for the gasifier
Use of ash and char:
*soil amendments
*lye production for:(ash may have to much carbon for quality lye production)
**soap products
**lye stabilized earth
Use of combustible gases:
*Steam Generator
*Power Cube
*Truck
*Car
*Kiln

=== Portability ===
Unit should be available in both portable and fixed arrangements. portable configurations should enable vehicle (trailer?) mounting.
reactor module design could be impacted. Will refractory cement handle the jostling around?

=== Modularity ===
A good design should allow for flexibility in design variability without loosing compatibility between the various components. This need may be more pronounced during development.
modules include:
*fuel bin
**different Sizes
**Autoloading? (designed with this in mind not necessarily needed)
*reactor core and ash collection
**variability in configuration depending on feedstock
**hearth material may vary depending on portability
*cyclone filter
*gas cooler
*filters
*manifold for gas delivery (optional)
*flare

===Capability===
How large a generator should this unit supply? A gasifier operating above designed capacity can cause damage to the reaction chamber and grate and operating significantly below capacity can lead to high tar production, the most difficult problem facing engines ran on producer gas.

===Other Considerations===
ability to interface with:
*screw type ash cleanout
*auto fuel loader

This report documents the design and manufacturing of a continuous screw pyrolysis unit within the scope of a capstone project.

ABSTRACT:
There is currently a need to design new energy and waste management systems which are capable of mitigating climate change while maintaining commercial viability. This report documents the overall system design and subsequent detailed design undertaken in the development of a proof of concept (POC) pyrolysis bioenergy system in the context of an undergraduate mechanical engineering CAPSTONE project. The project was selected based on the current need to design new energy and waste management systems capable of mitigating climate change while maintaining commercial viability. This report along with the manufactured POC will be used as a stepping stone towards the ultimate goal of manufacturing a fully functional prototype capable of mitigating climate change through the production of sustainable energy carriers from organic waste. The commercially viability of this project will depend on the trend in global markets to start pricing externalities such as carbon dioxide emissions. If this trend continues carbon markets will continue to develop and mature over time. Once these markets are fully integrated into our economic system companies will be aggressively seeking new forms of energy in order to avoid the cost of carbon dioxide emissions. The energy carriers generated through pyrolysis can be sold as sustainable energy sources, or in the case of Biochar, can be used as a carbon sink. Pyrolysis systems can thus produce sustainable sources of energy while simultaneously sequestering carbon from the atmosphere. Early entry into this underdeveloped market is critical for strategic placement and future commercial success.
