This is a two pot chulha with a chimney. It does not have a bottom grate, but the firemouth is deliberately kept large to provide more air to the burning fuel. In this model, about 80% of the total heat is delivered at the first pothole and only 20% at the second pothole. As a result, only the first pothole can be used for cooking, while the second pothole serves only to keep the food warm.
