DIY: How to Build an Outdoor Smokeless Wood Stove from Brick

on

An outdoor smokeless wood stove is a great addition to your backyard, providing a reliable heat source for cooking and warmth while minimizing smoke emissions. This guide will walk you through the process of building a durable and efficient smokeless wood stove using bricks.

Materials Needed:

  • Fire bricks (approximately 100-150, depending on the size of the stove)
  • Metal grating (to fit inside the stove)
  • Metal chimney pipe (4-6 inches in diameter and 6-10 feet in length)
  • Metal cutting tools (if the chimney pipe needs to be cut)
  • Fire-resistant mortar
  • Shovel and level
  • Trowel
  • Heat-resistant sealant
  • Optional: Steel plate for cooking surface

Step 1: Choose a Location

  1. Select a flat area: Choose a level, well-ventilated area in your backyard that is clear of any flammable materials. This will be the base of your stove.
  2. Clear the ground: Use a shovel to clear away any grass or debris. Ensure the ground is flat and level.

Step 2: Create the Base

  1. Lay the first layer of bricks: Arrange the fire bricks in a rectangular or square shape, depending on your desired stove size. This will be the base of the stove. Leave a small gap at the front for the air intake.
  2. Apply mortar: Use fire-resistant mortar between the bricks to secure them in place. Ensure the base is level.

Step 3: Build the Stove Walls

  1. Continue stacking bricks: Build up the walls of the stove by stacking additional layers of fire bricks on top of the base. Use mortar between each layer to secure the bricks.
  2. Leave space for the air intake: On one side of the stove, leave a gap near the bottom (about 4-6 inches wide) to serve as the air intake.
  3. Build the chimney outlet: As you build up the walls, leave an opening at the top where the chimney pipe will be installed. This should be on the opposite side of the air intake.

Step 4: Install the Grate

  1. Position the grate: About halfway up the stove, place a metal grate inside to hold the wood. The grate should be above the air intake to allow air to flow under the fire, promoting efficient combustion.
  2. Secure the grate: Ensure the grate is stable and securely positioned within the stove walls.

Step 5: Install the Chimney Pipe

  1. Prepare the chimney pipe: If necessary, cut the chimney pipe to your desired length using metal cutting tools.
  2. Install the chimney: Insert the chimney pipe into the outlet at the top of the stove. The pipe should extend several feet above the stove to ensure proper ventilation and draw smoke away from the fire.
  3. Seal the joints: Use heat-resistant sealant to seal the joints around the chimney pipe where it meets the bricks to prevent any smoke leaks.

Step 6: Create the Cooking Surface (Optional)

  1. Install a steel plate: If you want to use the stove for cooking, place a steel plate on top of the stove walls. This plate will serve as a cooking surface where you can place pots and pans.
  2. Secure the plate: Use mortar or metal brackets to secure the steel plate in place, ensuring it is stable and level.

Step 7: Finishing Touches and Testing

  1. Allow the mortar to cure: Let the mortar cure for at least 24-48 hours before lighting a fire. This will ensure the bricks and mortar are securely bonded.
  2. Test the stove: Light a small fire inside the stove and monitor the airflow and smoke output. The air intake and chimney should work together to create a smokeless burn. Adjust the chimney height or air intake size if necessary.

Step 8: Fine-Tuning and Usage

  1. Monitor the stove's performance: If you notice smoke escaping from the stove, check for gaps or leaks in the mortar and seal them with heat-resistant sealant.
  2. Use dry, seasoned wood: For the best performance, always use dry, seasoned wood. This will reduce the amount of smoke produced and improve the stove's efficiency.

Maintenance Tips:

  • Regularly clean the chimney pipe to prevent soot buildup and ensure proper ventilation.
  • Inspect the stove for any cracks or damage and repair them as needed with fresh mortar or sealant.
  • Keep the air intake clear of debris to maintain proper airflow.

Building an outdoor smokeless wood stove from bricks is a practical and rewarding project that will provide you with a reliable outdoor cooking and heating solution. With the right materials and careful construction, you can enjoy the benefits of a smokeless fire in your backyard for years to come.
