IFB stainless liner school rocket stove
IFB stainless liner school rocket stove skirt detail

On a recent trip to Haiti, I completed the first prototype of a new school rocket stove. This one has a 26 ga 330 stainless steel firebox liner, 2½" insulating firebrick walls, and galvanized steel outer shell. The skirt is 304 stainless inside, 1" ceramic fiber in the skirt floor and walls, and galvanized steel outer. The mouth and firebox are 6½" x 6½". The pot is 40 qts with the top diameter about 1/4" larger than the diameter near the bottom, and is imported. The locally available spherical bottom pots made skirt construction extremely difficult. We hope to someday produce this stove in quantity at a combined vocational school/stove factory.

1 The Basic Mechanisms of the Rocket Stove. With the lessons from people like Rok Oblak, Richard Stanley and the Aprovecho Institute the author began learning to build the holey roket stove in his workshop at Daet, Camarines Norte. With sheer perseverance and amidst scarcity, he was able to create several models and delivered skills training to poor people in Camarines Norte, Sorsogon and recently in Bulacan.

2. Among the many feedbacks from the users are the limitation of the holey roket stove in terms of (1) fragility in handling and (2) capacity to receive bigger loads when cooking for bigger occasions and events and for food business. In response, one of the models was picked up for reinforcements.

3. The Innovations as of July 2013
