PART1 Exstreme simple gasifier: DriZzleR mini

Introduction

This tutorial provides a step-by-step guide to building the DriZzleR mini gasifier, a simple and innovative gasifier design. This project is designed for beginners and allows for customization and experimentation, serving as a foundation for further development. The goal is to empower you to create your own gasifier and contribute to the growing community.

Step 1: Gather Materials

Collect the following materials needed for the gasifier:

• A standard 30-liter paint bucket
• A piece of stovepipe
• Two metal rings (preferably made by a blacksmith)
• Ceramic cardboard for sealing
• A grate for the burning chamber
• A reactor (recommended to purchase from a reliable source)

Step 2: Prepare the Stovepipe and Rings

1. Attach the Rings:

   • One ring should be welded to the stovepipe.
   • The second ring should be perforated to match the first and slide over the stovepipe.
   • Ensure both rings can press the lid of the paint can tightly and gas-tight.

2. Create the Fuel Tube:

   • Weld a closed ring with a 75mm opening at the bottom of the fuel tube.
   • Attach a reduction piece from 75mm to 210mm.

Step 3: Assemble the Burning Chamber

1. Insert the Grate:

   • Place the grate above the fuel tube inside the paint bucket.
   • This setup allows for airflow and combustion.

2. Install the Reactor:

   • Position the reactor, which facilitates gas expansion.
   • Ensure it is correctly aligned with the gas exit.

Step 4: Insulate the Gasifier

1. Wrap the Assembly:
   • Surround the assembled gasifier with an insulating material to retain heat.
   • This helps improve efficiency during operation.

Step 5: Perform Initial Testing

1. Flare the Gasifier:

   • Once assembled and insulated, prepare to flare the unit.
   • Monitor the flare closely; it provides valuable feedback on the gasifier's performance.

2. Observe and Adjust:

   • Take notes on the flare's behavior and make adjustments as needed.
   • Use this information to refine your design and improve functionality.

Conclusion

The DriZzleR mini gasifier is a straightforward project that can be completed in a couple of hours and requires minimal skills. By following these steps, you can build your own gasifier and begin experimenting with gasification. Remember to document your experiences and share your innovations with the community. Happy building!
