The design and operation of an inverted cone, scalable vapor condenser, drawing cooling air from beyond the boundary layer and optionally working as a part of a gastight setup, are described and discussed. Besides its main use as a reflux condenser, it can also be used in one-plate distillations.

The combination of large volumes of woody fuel needing disposal after forestry activities and evolving regulatory restrictions makes traditional methods of pile burning increasingly difficult. Alternatively, using small kilns to pyrolyze these fuels on-site yields a potentially valuable product: biochar. In this article, we describe an educational…
