Zimmerman, H G

This patent describes a downdraft stove, a tubular grating assembly for positioning in a reaction chamber which consists of: a substantially vertically oriented central tube open at its upper end and connected at its lower end to an air inlet opening; a cap supported above the open upper end for protecting the open upper end from entry of matter, the space between the cap and the upper end constituting a primary air inlet nozzle; grating tubes radially distributed around and taking off substantially horizontally from and communicating with the central tube, thereby defining a grating, and thence turning downwardly and being open at their downward ends to thereby constitute secondary air inlets.
